Non void methods - there are 2 things there
- The method header indicates its non void - it has int / double / string / bool / float etc as returntype
- it has a return statement as last statement in method
public int getArea(int hello); ^ that is the method header ( it is non void ) Non void methods HAVE to have a return statement return statement ends method
You call a non void method with a variable to grab what it returns int a = mySquare.getArea(30); ^ a == 300
public void setlength(int rectlength); ^ returns nothing ^ does not need a return statement ^ just does stuff
mySquare.setlength(15); ^ square length is now 15
