java---实现数组的输出

简单的字符串与变量的输出，，，

class ArrayShow {public static void main(String[] args) {int a[][] = {{1,2,3},{4,5,6},{7,8,9}};int a2[][] = new int [3][];//输出数组for (int i = 0; i < 3; i++){for (int j = 0; j < 3; j++){System.out.print(a[i][j]);}System.out.println();}//具体输出System.out.println("具体输出");for (int i = 0; i < 3; i++){for (int j = 0; j < 3; j++){System.out.println("a["+i+"]["+j+"]="+a[i][j]+" ");}}//复制并输出a2 = a.clone();System.out.println("输出复制后的值：");for (int i = 0; i < 3; i++){for (int j = 0; j < 3; j++){System.out.println("a2["+i+"]["+j+"]="+a[i][j]+" ");}}}}
