Take the following example: In the above example we are overloading the method “area” to find the area for different figures (rectangles, squares, circles). The argument lists of all three methods are different. Because they all have different argument lists, they are all overloaded methods. They also have different return value. Overloading is the simpler concept. These are the key takeaways from the exam. Any number of overloaded method can exist in the same sub-class or class. However, the argument lists of the overloaded methods must be different. Overloaded methods can be considered different methods. They have the same name, but different argument lists, return types, and access modifiers.
