Java: Programming - Flip Name

Name ______________________

Write a method, flipName, which has a string parameter which contains a name in last, first format. It should return the name in first last format as a string, or "ERROR" if the argument was not correctly formed.

For example, the following main program.

public static void main(String[] args) {
    System.out.println(flipName("Maus, Michael"));
    System.out.println(flipName("Einstein, Albert"));
    System.out.println(flipName("Prince Albert"));
    System.out.println(flipName(null));
}

The output would be.

Michael Maus
Albert Einstein
ERROR
ERROR

Method only. You only have to write the method, not an entire program.

Error processing If the parameter is null, or if there is no ", ", return the string "ERROR".
