How to run a java program


Compiling and running a java program is very easy after JDK installation. Following are the steps −

  • Open a command prompt window and go to the directory where you saved the java program (MyFirstJavaProgram.java). Assume it's C:\.

  • Type 'javac MyFirstJavaProgram.java' and press enter to compile your code. If there are no errors in your code, the command prompt will take you to the next line (Assumption: The path variable is set).

  • Now, type 'java MyFirstJavaProgram' to run your program.

  • You will be able to see the result printed on the window.
