Setting your Java environment

Get your hands on your keyboard and type Oracle Java installation in google search bar or follow the steps here below.

  1. Go to “”
  2. Chose your machine’s version of installer and download. It is a good practice to choose an installation directory rather than your program Files in Windows so windows security feautures would not block your java processes.
  3. Once you finish installation define a system environmnet variables from system properties on Windows machines. Add a user variable as JAVA_HOME and continue defining installation directory. As in the example here : you can check your Java installation file path from your commandline. Type “java -version” to check if your java installation is integrated with the system, if not you may again need a restart of your machine. If all is well type “echo %JAVA_HOME%” to see your java installation path which needs to be entered as variable value above in the window for your JAVA_HOME variable name entry. If above echo code does not work try these : “where java” in windows or “which java” for unix based systems like MacOs or Linux. Another method you can use in CMD in Windows is “for %i in (javac.exe) do @echo. %~$PATH:i”
  4. Then edit Path in your System variables and add a new environment variable entry. This is simply your Java bin folder you can find it in the installation path. A sample entry would as below.
