Given the code fragment:
Consider below codes of 3 java files:
1. //M.java
2. package com.sampleproject.oca;
3.
4. public class M {
5. public void printName() {
6. System.out.println("M");
7. }
8. }
1. //N.java
2. package com.sampleproject.oca;
3.
4. public class N extends M {
5. public void printName() {
6. System.out.println("N");
7. }
8. }
1. //Test.java
2. package com.sampleproject.oca.test;
3.
4. import com.sampleproject.oca.*;
5.
6. public class Test {
7. public static void main(String[] args) {
8. M obj1 = new M();
9. N obj2 = (N)obj1;
10. obj2.printName();
11. }
12. }
What will be the result of compiling and executing Test class?
Which of the following are Java Exception classes?
Select 3 options.
Given the code fragment:
Below is the code of Test.java file:
1. package com.udayan.oca;
2.
3. import java.util.ArrayList;
4. import java.util.List;
5.
6. public class Test {
7. public static void main(String [] args) {
8. List
9.
10. list.add(27);
11. list.add(27);
12.
13. list.add(new Integer(27));
14. list.add(new Integer(27));
15.
16. System.out.println(list.get(0) == list.get(1));
17. System.out.println(list.get(2) == list.get(3));
18. }
19. }
What will be the result of compiling and executing Test class?
