How to Setup Java on Windows

Here are the steps to set up Java on a Windows operating system:

1. Download the latest version of Java from the Oracle website (https://www.oracle.com/java/technologies/javase-downloads.html).

2. Run the downloaded installer package and follow the instructions to install Java on your computer.

3. Once the installation is complete, open the command prompt and type "java -version" to verify that Java has been installed properly.

4. Next, set the JAVA_HOME environment variable to the location of the installed Java. You can do this by: a. Right-clicking on the Computer icon on the desktop or in the Start menu and selecting Properties. b. Click on Advanced system settings. c. Click on Environment Variables. d. Under System variables, click on New. e. Type JAVA_HOME for the variable name and the path to your Java installation for the variable value. (e.g. C:\Program Files\Java\jdk{version})

5. Finally, add the Java bin folder to your system's PATH environment variable by: a. Under System variables, scroll down to find the Path variable, and click on Edit. b. Click on New and type %JAVA_HOME%\bin.

6. Verify the setup by opening a command prompt and typing "javac" (without quotes). This should display the options for the Java compiler.

Note: These instructions are for Windows operating system. The steps may vary slightly for other operating systems.

Additionally, you may want to install an Integrated Development Environment (IDE) such as Eclipse or IntelliJ IDEA, to make it easier to write, run and debug your Java code.
