How to compile a java program

Compiling 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. Assume it's C:\.

  • Type 'javac' 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).

The file is compiled and you can see MyFirstJavaProgram.class file generated in the same folder.
