What is Java?

Java is considered one of the most popular programming languages. Java is a typed object-oriented programming language developed by Sun Microsystems (and subsequently acquired by Oracle). Development is mainly performed by a community organized through the Java Community Process. The language and the main technologies that implements it are distributed under the GPL but the trademark rights are owned by Oracle Corporation. Code written in Java (using the JVM – Java Virtual Machine) is transformed into bytecode and due to this, programs can run on any system where the JVM is installed. Therefore, Java is often called a cross-platform language. Most often, Java is used to develop backend programs and android applications.

Java JDK and Java JRE

There are two packages needed to install Java, the Java JDK and Java JRE.

• Java JRE (Java Runtime Environment) – is necessary for running programs on computers and contains JVM, class libraries (Java Class Library), console commands. JRE is not enough for programming and creating programs. Install JRE only for programs that need to use Java in their projects.
• Java JDK (Java Development Kit) – is necessary for developers and it includes JRE, javac compiler and other tools necessary for development in Java. If you plan to use Java in development, you need to use this version of the package.

Java SE and Java EE.

There are 2 main classifications of Java platforms, Java SE and Java EE. These are defined below.

• Java SE – This is the Java Standard Edition. It is the main Java edition that contains the compiler, API, JRE and is suitable for creating custom applications, primarily for desktop systems.
• Java EE – This is the Java Enterprise Edition. It includes a set of specifications used mainly for creating enterprise-level software.

Java versions.

Currently, the latest version is Java 13, however, the most popular and widely used version is Java 8. In many circumstances, it is not always the best choice to use the latest versions in programming languages. The reason being because many times, there are functions that are introduced in later versions which do not always work well with older versions.

OpenJDK

We will use OpenJDK as this software is a project created to be an open-source, fully compatible Java JDK consisting exclusively of free and open-source code. By installing this package we can use it for free, but other implementations of Java may require a paid option.

SDKMAN

One other thing, if you are planning to use Java in a development environment, we would advise the use of SDKMAN. This is a command-line utility which allows us to install multiple versions of Java, and it handles the variable settings for us. It is convenient to use, but we will try to do accomplish the installation without it first, and then show the process using the help of SDKMAN.

Installation on Ubuntu 18

Install OpenJDK

Let’s begin by installing Java OpenJDK 13 on Ubuntu 18.04. First, we need to check and see if we have Java installed using the following command.

This indicates that Java is not currently installed.

Download Java SDK 13

Our next step includes downloading the Java SDK (or software developer kit). We will accomplish this by using the wget command.

Working Directory

Java Download On Mac

Next, we will create a working directory where Java will reside, change directories into that folder, copy the downloaded file into that directory, and finally, extract the tar.gz file into its directory.

Set Environment Variables

The Set Environment Variables step is necessary because when using Java, Ubuntu needs to know where the program is located to run it from, and which Java version to use by default. To modify this, we will use the nano text editor. First, open the file in Nano.

How To Download And Install Java On Mac Os

Next, scroll to the bottom of the file and paste this information.

Finally, we press ctrl + O + Y + Enter then ctrl + X + Enter to save and close the file.

Finishing the Configuration Setup

Our last step involves updating the information in our system to point the new program and its options. In this case, we update the information regarding the Java installation.

Version Check

As a final verification, we can check the installation and the version using the following command.

Installation on Windows 10.

In order to install the Windows version of Java, we need to visit the official Java website and download the Windows executable. Once at the site, the licensing options are outlined in green. It states “The new Oracle Technology Network License Agreement for Oracle Java SE is substantially different from prior Oracle JDK licenses. The new license permits certain uses, such as personal use and development use, at no cost — but other uses authorized under prior Oracle JDK licenses may no longer be available. Please review the terms carefully before downloading and using this product. An FAQ is also available.

Commercial license and support is available with a low cost Java SE Subscription.” We will scroll down to see the available downloads.

We will be downloading the jdk-13.0.2_windows-x64_bin.exe version.

After we click on the selected version, we must accept the user agreement.

Once the download completes, run the executable.

Click next and agree with the selected folders by default. Click Close when complete.

Setup Environment Variables

JAVA_HOME is a variable that points to the directory in which Java is installed. Programs use it to determine where Java is located.

Click on the keyboard combination Win+R, the Run window will pop up, and we then enter the command control / name Microsoft.system.

Next, select Advanced system settings

Now, click on Environment Variables.

Now, choose Path, and then click on New.

Enter the name: JAVA_HOME. Next, specify the path. If you selected the default path, you will see the path C:Program FilesJavajdk-13.0.2

Next, select PATH edit.

Then, we click New and enter the following.

%JAVA_HOME%bin

And click OK in all open windows.

Now, to verify everything, we will open the run console with the Windows+r command and enter cmd and then press enter.

Now, we will enter the following command to check if everything works as expected.

Next, we will check the Java version using the following command.

Excellent! Let’s move on.

Installation on MacOS

There are several options on how to do it. We can do the same way as we did in Ubuntu or Windows. Since we are installing the JDK version for developers, and in the future we will need to be able to install some programs, we will install through the console. We launch the console. If you do not know how to enter the terminal, open the directory below, then in Applications -> Utilities -> Terminal.

How To Download And Install Java On Mac Windows 10

For macOS we will use the SDKMAN utility, it is often used when you need to install several versions and configure it, SDKMAN does everything by itself. Conveniently, this installation can be used on macOS and Ubuntu.

Add SDKMAN Repository

In the initial step, we will install the SDKMAN repository.

Set Environment Variable

Next, we will set the environment variable.

Now, we can check to ensure SDKMAN is installed.

Now, we can review a list of Java versions.

Install JDK 13

Next, we will select the version JDK 13 and install it.

Install Java For Mac

Now we can set the default Java version to use.

Verify Version

Lastly, we can check the version of Java using the following command.

And that’s it! We installed Java on macOS.

Conclusion

In this tutorial, we learned what Java is, which versions are available to install on multiple platforms. Finally, we learned how to install, configure and run Java on Ubuntu, Windows and MacOS.

How To Download And Install Java On Mac Catalina

Installing Eclipse

1. If you already have Eclipse installed on your Mac, you need to get rid of it. To do so, first quit Eclipse if you're currently running it. Then, go to your workspace folder (probably in Documents/workspace) and save anything there that you want to keep, because you're about to get rid of this folder. Next, drag the workspace folder to the Trash.

   Go to your Applications folder. One way to get there is, from the Finder, type command-shift-A. You'll a folder named eclipse in there; drag the eclipse folder to the Trash. If you have an Eclipse icon in your dock, remove it from the dock.

2. Now you're ready to download and install the newest version of Eclipse. Go to this website. You'll see a window like this:

   Scroll down until you see 'Eclipse IDE for Java Developers' and click where it says 64 bit under Mac OS X.

3. You will see this window:

   Click on the yellow download button. If asked, click on 'Open with Archive Utility (default)' and then click OK. The download might take a few minutes. You should not feel compelled to donate.

4. After the download completes, folders should automatically expand. If they don't, double-click on the .tar file. When that's done, you should see a folder named eclipse in your Downloads folder. When you open your Downloads folder, if you see Applications under the Favorites on the left side of the window, you should drag the eclipse folder into Applications. If you don't see Applications, then open a new window for Applications (from the Finder, command-shift-A), and drag the eclipse folder into Applications.

5. Open your Applications folder, and then open the eclipse folder. You'll see an item named Eclipse; if you like, drag its icon into the dock so that you'll be able to launch Eclipse easily.

6. Launch Eclipse. If you're asked whether you want to open it, of course you do; click Open. You'll see a window like this:

   It will have your user name rather than mine (scot). Select where you want your workspace to be; I recommend the default of your Documents folder. Click the checkbox for using this location as the default, and then click OK.

7. You'll see a window like this:

   Click on the Workbench arrow in the upper right that I've circled. You shouldn't see this screen again, even if you quit Eclipse and relaunch it.

8. You'll get an empty workbench like this:

   We won't be using the 'Task List' and 'Connect Mylyn' windows. Click the 'x' on each to close it. Press the mouse on the Window menu item, then choose 'Perspective', and finally choose 'Save Perspective as...'. Enter 'cs10' for the name of this perspective and press return. Your workbench will now look like this:

   You have now installed Eclipse!

Configuring Eclipse

You don't have to configure Eclipse the way I do, but you'll probably avoid some confusion if you do. Here's how.

How To Install Java On Mac

1. In the Eclipse menu bar, click on the Eclipse menu and then on 'Preferences...'. You'll see a window with two panes. On the left pane is a list of types of things you can configure.

2. Click on the triangle to the left of General. Then click on the triangle to the left of Appearance. Then click on 'Colors and Fonts.' You should see a window like this:

3. In the window in the middle, click on the triangle next to Java. Then double-click on 'Java Editor Text Font':

4. You'll see this window:

   On the right, where you can select the size, click 12. Then close this window by clicking on the window's close button.

5. Close up the General preferences by clicking on the triangle to the left of General. Click the triangle next to Java and then click the triangle next to 'Code Style.' Then click Formatter. Here's what you should see:

6. Click the button that says 'New...'. You'll see a window such as this one:

   You can type in any profile name you like. I used 'CS 10':

   Click OK.

7. You should see a window like this:

   Change the tab size to 2:

   You'll see that the indentation size automatically changes as well.

8. Click on 'Blank Lines,' and after 'Between import groups' and 'Before declarations of the same kind,' change the values 1 to 0:

9. Click on 'Control Statements,' and check the first four boxes as I've done here:

   Click OK.

10. Now click on triangles to close up Java. Click on the triangle next to Run/Debug, and then click on Console:

11. Click on the green color sample next to 'Standard In text color.' You'll get a color picker:

12. Slide the slider on the right down, so that you get a dark green. (You're at Dartmouth. What other color could you possibly want?)

    Close the color picker window by clicking its close button, and click OK again to close the Preferences window.

And you're done!
