二维数组的遍历

import java.util.Random;


public class test {

	public static void main(String[] args) {
		Random random=new Random();
		int [][] array=new int[5][5];
		for(int i=0;i<5;i++){
			for(int j=0;j<5;j++){
				array[i][j]=random.nextInt(100);
				System.out.print(array[i][j]+"  ");
			}
			System.out.print("\r");
			
		}
		for(int i=0;i<array.length;i++){
			for (int j = 0; j <array[i].length; j++){
				System.out.println(array[i][j]);
			}
		}
		
	}

}
