How many String objects are there in the HEAP memory, when control is at Line 9?

1. package com.udayan.oca;

2.  

3. public class Test {

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

5.          String s1 = new String("Java"); //Line 3

6.          String s2 = "JaVa"; //Line 4

7.          String s3 = "JaVa"; //Line 5

8.          String s4 = "Java"; //Line 6

9.          String s5 = "Java"; //Line 7

10.  

11.          int i = 1; //Line 9

12.  

13.      }

14. }

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. }
