The command "javac MyClass.java" is used to compile the file "MyClass.java" into a Java class file. In order for the command to work, you must first make sure you are in the same directory or folder where the file is located. Saving with a .comp extension or executing the java.sun.com program are not necessary for this command to work, and closing all other windows on your computer system is also not relevant.
