Java Array Program

CODE:

public class Main {
	public static void main(String[] args) {
		int a[]=new int[3];
		a[0]=5;
		a[1]=15;
		a[2]=50;
		
		System.out.println(a[0]);
		System.out.println(a[1]);
		System.out.println(a[2]);
		System.out.println("Array length : "+a.length);
		
		//2d array 
		System.out.println("\n2D Array ");
		int a2[][] = new int[2][3]; 
		a2[0][0]=100;
		a2[0][1]=200;
		a2[0][2]=300;
		a2[1][0]=400;
		a2[1][1]=500;
		a2[1][2]=600; 
		
		System.out.println(a2[0][0]); 
		System.out.println(a2[0][1]);
		System.out.println(a2[0][2]);
		System.out.println(a2[1][0]);
		System.out.println(a2[1][1]);
		System.out.println(a2[1][2]);
		
		
		//jagged array 
		System.out.println("\njagged Array ");
		int a3[][] =new int [3][];
		a3[0]=new int [3];
