EXPERTY DESIGNED 1Z0-808 PRACTICE TEST

Given code of Test.java file:

1. package com.sampleproject.oca;

2.  

3. public class Test {

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

5.         try { //outer

6.             try { //inner

7.                 System.out.println(1/0);

8.             } catch(ArithmeticException e) {

9.                 System.out.println("INNER");

10.             } finally {

11.                 System.out.println("FINALLY 1");

12.             }

13.         } catch(ArithmeticException e) {

14.             System.out.println("OUTER");

15.         } finally {

16.             System.out.println("FINALLY 2");

17.         }

18.     }

19. }

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

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.         /*INSERT*/ x = 7, y = 200;

6.         System.out.println(String.valueOf(x + y).length());

7.     }

8. }

Which of the following options, if used to replace /*INSERT*/, will compile successfully and on execution will print 3 on to the console?

Select 3 options.
