Answer:
- What two classes are defined in this code?
- HelloObject and HelloTester
- What method is in the first class?
- A
HelloObjectobject has aspeak()method.
- A
HelloObject object 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.
Methods in classes you define can return values
just as do methods from library classes.
The return statement
is used to hand back a value to
the caller.
If you want a method that does something, but does not return a value 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!");
}
Examine this method
void greeting()
{
System.out.println( "Good Day" );
return;
}
Is it correct? (Assume it is defined in a class that is otherwise OK.)
