Here is the Code:

1. import java.io.*;
2. class Main {
3. public static void main (String[] args) {
4. int[] a = {1, 2, 3};
5. System.out.println(a[2]);
6. for(int i=0;i<a.length;i++)
7. {
8.     System.out.println(a[i]);
9. }
10. int[] b = new int [5];
11. for(int i=0;i<b.length;i++)
12. {
13.     b[i]=5;
14.     System.out.println(b[i]);
15. }
16. }
