2. Draw the sequence diagram for the following code. public class SeqDiag { public static void main (String [] args) { func(); } public void func() { public class ClassA { ClassA objA = new ClassA(); ClassA objB = new ClassA(); int val = objA.get(); int val1 = objB.get(); objA.put(val + 1); objB.put(val1 - 1); static private int num = 10; public int get() { return num; } public void put(int val) { num = val; }
