21. What would have been the output of the preceding program if the third method had contained the following
statements?
public static void third() {
first();
second();
System.out.println("Inside third method");
}
22. What would have been the output of the Strange program if the main method had contained the following
statements? (Use the original version of third , not the modified version from the most recent exercise.)
public static void main(String[] args) {
second();
first();
second();
third();
}
23. What is the output of the following program? (You may wish to draw a structure diagram first.)
1 public class Confusing {
2 public static void method2() {
3 method1();
4 System.out.println("I am method 2.");
5 }
6
7 public static void method3() {
8 method2();
9 System.out.println("I am method 3.");
10 method1();
11 }
12
13 public static void method1() {
14 System.out.println("I am method 1.");
15 }
16
17 public static void main(String[] args) {
18 method1();
19 method3();
20 method2();
21 method3();
22 }
23 }
