Problem 22) Below is the outline of a simple class called Busywork. In the blank space provided in e elass add two methods to the class. The two methods that you add can make use of the two gven methods setNumber() and getNumber(). (a) Add a method increment() that adds 1 to the value of m. (b) Add a method decrement() that returns a Busywork object whose value of m is one less than the value stored in the calling object. This method should not modify the m in the object the method is called on class Busywork private int m e; public void setNumber(int newM) thism newM; = public int getNumber() return this.m; // write the methods increment() and decrement() )//BusyWork
