Compile the Source Code
Assuming that you have a file named MediaPlayer.java (or an equivalent name), use the following command line to compile its source code at a command prompt (such as the Windows MS-DOS command prompt):javac MediaPlayer.java
Assuming successful compilation, the following class files will be created:
MediaPlayer.class (the starting class)
MediaPlayer$1.class (the window listener anonymous inner class)
If you encounter compiler error messages, keep the following points in mind:
You might have entered incorrect source code.
You might have declared the MediaPlayer class public and not saved the source code in a file named MediaPlayer.java.
You might have forgotten to include a .java file extension with the filename when specifying the javac command line.
