11.              System.out.println("ONE");

12.          } catch (FileNotFoundException ex) {

13.              System.out.println("TWO");

Question 2

What will be the result of compiling and executing Test class?

package com.udayan.oca;

public class Test {

     static String msg; //Line 2

     public static void main(String[] args) {

         String msg; //Line 4

         if(args.length > 0) {

             msg = args[0]; //Line 6

         }

         System.out.println(msg); //Line 8

     }

}


Answer: C
Question 3

Given code:

package com.udayan.oca;

 

public class Test {

    public static void main(String[] args) {

        /*INSERT*/

        arr[1] = 5;

        arr[2] = 10;

        System.out.println("[" + arr[1] + ", " + arr[2] + "]"); //Line n1

    }

}

And below statements:

1. short arr [] = new short[2];

2. byte [] arr = new byte[10];

3. short [] arr; arr = new short[3];

4. short [2] arr;

5. short [3] arr;

6. int [] arr = new int[]{100, 100};

7. int [] arr = new int[]{0, 0, 0, 0};

8. short [] arr = {};

9. short [] arr = new short[2]{5, 10};

How many above statements can be used to replace /*INSERT*/, such that on execution, code will print [5, 10] on to the console?


Answer: C
Question 4

Consider below code:

1. package com.udayan.oca;

2.  

3. public class Test {

4.     public static void main(String[] args) {

5.         StringBuilder sb = new StringBuilder();

6.         try {

7.             for(;;) {

8.                 sb.append("OCA");

9.             }

10.         } catch(Exception e) {

11.             System.out.println("Exception!!!");

12.         }

13.         System.out.println("Main ends!!!");

14.     }

15. }

What will be the result of compiling and executing Test class?

Question 5

Consider below code of Test.java file:

1. package com.sampleproject.oca;

2.  

3. public class Test {

4.     public static void main(String[] args) {

5.         String [][] arr = { {"%", "$$"}, {"***", "@@@@", "#####"}};

6.         for(String [] str : arr) {

7.             for(String s : str) {

8.                 System.out.println(s);

9.                 if(s.length() == 4) //Line n1

10.                     break; //Line n2

11.             }

12.             break; //Line n3

13.         }
