Int[] a={1,2,3};
 for (int i:a)
 System.out.print (i+ "");

Two-dimensional arrays:

Import Java.util.Scanner;

public class Tet {public
	static void Main (string[] args) {
		//int[][] b={{1,2,3},{4,5,6}}; line
		int[][] A=new int[5][];//must specify the number of rows for
		(int i=0;i<5;i++)
			a[i]=new int[3];//explicit Columns
		} for
		(int[) i:a)
			(int j:i)
				System.out.print (j+ "");
