}- A method returns to the code that invoked it when it completes all the statements in the method, reaches a return statement, or throws an exception, whichever occurs first.
- You declare a method's return type in its method declaration. Within the body of the method, you use the returnstatement to return the value.
- Any method declared void doesn't return a value. It does not need to contain a return statement, but it may do so. In such a case, a return statement can be used to branch out of a control flow block and exit the method.
- The data type of the return value must match the method's declared return type.
