- When you run a Java application, the system locates and runs the main method for that class.
- The main method must be public, static, and void.
- The main method must accept a single argument of type String[].
- The arguments in the String array passed to main are program arguments, or command-line arguments.
- An application can have any number of main methods, because each class can have one.
- This is good, because each class can have a main method that tests it's own code.
