The use of enhanced for loops in one-dimensional and two-dimensional arrays in Java _java

One-dimensional arrays:

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

Output: 1 2 3

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)
		{for
			(int j:i)
			{
				System.out.print (j+ "");

}}}}

Output:

0 0 0
0 0 0
0 0 0
0 0 0
0 0 0

The above is the small series for you to bring to the Java enhanced for loop in one-dimensional array and two-dimensional array of the full content of the method, I hope to help you, a lot of support cloud Habitat Community ~
