Below is the code of Test.java file:
1. package com.udayan.ocp;
2.
3. class Outer {
4. static class Inner {
5. static void greetings(String s) {
6. System.out.println(s);
7. }
8. }
9. }
10.
11. public class Test {
12. public static void main(String[] args) {
13. /*INSERT*/
14. }
15. }
Which of the following 2 options can replace /*INSERT*/ such that there on executing class Test, output is: HELLO!?
Given code of Test.java file:
1. package com.udayan.ocp;
2.
3. public class Test {
4. private static void div(int i, int j) {
5. try {
6. System.out.println(i / j);
7. } catch(ArithmeticException e) {
8. throw (RuntimeException)e;
9. }
10. }
11. public static void main(String[] args) {
12. try {
13. div(5, 0);
14. } catch(ArithmeticException e) {
15. System.out.println("AE");
16. } catch(RuntimeException e) {
17. System.out.println("RE");
18. }
19. }
20. }
What will be the result of compiling and executing Test class?
Consider the code of Test.java file:
1. package com.udayan.ocp;
2.
3. class Player {
4. String name;
5. int age;
6.
7. Player() {
8. this.name = "Yuvraj";
9. this.age = 36;
10. }
11.
12. public String toString() {
13. return name + ", " + age;
14. }
15.
16. public Class getClass() {
17. return super.getClass();
18. }
19. }
20.
21. public class Test {
22. public static void main(String[] args) {
23. System.out.println(new Player());
24. }
25. }
What will be the result of compiling and executing Test class?
Given code of Test.java file:
1. package com.udayan.ocp;
2.
3. import java.util.Arrays;
4. import java.util.Comparator;
5. import java.util.List;
6.
7. public class Test {
8. public static void main(String[] args) {
9. List
10.
11. System.out.println(list.stream().max(Comparator.comparing(a -> a)).get()); //Line 1
12.
13. System.out.println(list.stream().max(Integer::compareTo).get()); //Line 2
14.
15. System.out.println(list.stream().max(Integer::max).get()); //Line 3
16. }
17. }
Which of the following statement is true?
