A good answer might be:

• What two classes are defined in this code?
  • HelloObject and HelloTester
• What method is in the first class?
  • An object of HelloObject type has a speak() method.

Method definitions look like this:

returnType methodName( parameterList )
{
  // Java statements

  return returnValue;
}

The returnType is the type of value that the method hands back to the caller of the method. Your methods can return values just as do methods from library classes. For example the length() method of class String returns an int type. The return statement is used by a method to hand back a value to the caller.

If you want a method that does something, but does not hand a value back to the caller, use a return type of void and do not use a return value with the return statement. The return statement can be omitted; the method will automatically return to the caller after it executes. Here is the method from the example program:

  // method definition
  void speak()
  {
    System.out.println("Hello from an object!");
  }

QUESTION 8:

Does this method have a parameter list?
