Given the code fragment:
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 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. }
14. }
15. }
