Question
Consider the following class Sample and the method foo. Indicate whether the following statements are true or false
with a brief explanation.
1. public class Sample
2. {
3. public void foo(int x, int y)
4.{
5. if (x == 2) {
6. System.out.println("x" + "y");
7. }
8. else {
9. double z = 3.0;
10. if (y == 3) {
11. z = 1.0;
12. }
13. System.out.println(x + y + z);
14. }
15. }
16. }
1. Calling foo(0,2) will print 5.0 as a result.
2. Calling foo(2,3) will print 6.0 as a result.
3. Calling foo(4,2) will print 9 as a result.
4. Calling foo(2,3) will print xy as a result.
5. Calling foo(-2,3) will print 3.0 as a result.
