方法的参数是二维数组
public class ArrayTest { public static void main(String[] args) { //二维数组 int [] [] a ={{65,76,2,12},{23,45,5},{12,23,4}}; Array(a); } public static void Array(int[][] a){ for (int i = 0; i <a.length ; i++) {//负责纵向3层 for (int j = 0; j <a[i].length ; j++) {//负责横向 System.out.print(a[i][j]+" "); } System.out.println(); } } }
