This section will help you download Java and set it up on your computer. These are the steps for setting up the environment.
Java SE can be downloaded from the link Download Java. A version that is compatible with your operating system can be downloaded.
Follow these instructions to download Java. Run the.exe file to install Java on your computer. After Java has been installed on your computer, you’ll need to configure environment variables so that the correct installation directories are pointed to.
Windows Path Configuration
Assuming Java has been installed in the c:Program filesjavajdk directory
Right-click on “My Computer” and choose “Properties“.
Click the “Environment variables” button under the “Advanced” tab.
Change the ‘Path” variable to include the path to the Java executable. Example, if the path is currently set to ‘C:\WINDOWS\SYSTEM32’, then change your path to read ‘C:\WINDOWS\SYSTEM32;c:\Program Files\java\jdk\bin’.
The Path to Linux, UNIX and Solaris
The environment variable PATH should point to the location where Java binaries are installed. If you need help, refer to your shell documentation.
For example, if bash is your shell, you’d add the following line at the end of your “.bashrc”: export PATH =/path/to/java.$PATH.
Popular Java Editors People are Used
A text editor is required to write Java programs. There are many more advanced IDEs on the market. For now, however, consider the following:
Notepad – You can use any text editor on Windows, such as TextPad or Notepad (recommended for this tutorial)
Netbeans – A Java IDE that is open-source and free which can be downloaded from https://www.netbeans.org/index.html.
Eclipse – Eclipse is a Java IDE that was developed by the Eclipse open-source community. It can be downloaded here
Java Developer Kit (JDK), and Java ID
We will now be presenting steps for Windows Operating Systems as listed.
Steps-by-step Windows’ Environment Setup.

Step 6: Click OK to save the settings and you’re done! To verify that the installation was successful, open the command prompt. Type javac -version. You’ll see that Java is running on your computer.
Note: Type javac at the command prompt to verify that the compiler has been set up. A list will appear that is related to javac.
A Java IDE (Integrated Development Environment) is recommended if you intend to work more with Java. An IDE includes a code editor that supports syntax highlighting, code completion and code generation. It often integrates with version control systems. A IDE makes it simple to compile and execute Java code from within the IDE.
Top Three Java IDEs.
Eclipse
IntelliJ IDEA
NetBeans
All three IDEs in the past and they are all very good today. IntelliJ IDEA offers a free community edition that will allow you to get started in Java. Eclipse and Netbeans can be downloaded completely free.
