第八章第二十九题(相等的数组)(equal array)
-
8.29(相等的数组)如果两个二维数组m1和m2具有相同的内容,则认为它们是相同的。编写一个方法,如果m1和m2是相同的话,返回true。使用下面的方法头:
public static boolean equals(int[][] m1,int[][] m2)
编写一个测试程序,提示用户输入了两个3x3的整数数组。显示两个矩阵是否是严格相同的。下面是一个运行示例:
Enter list1:51 22 25 6 1 4 24 54 6
Enter list2:51 25 22 6 1 4 24 54 6
The two arrays are identical
8.29(equal array)Two two dimensional arrays M1 and M2 are considered identical if they have the same content. Write a method that returns true if M1 and M2 are the same. Use the following method header:
public static boolean equals(int[][] m1,int[][] m2)
Write a test program to prompt the user to input two 3x3 integer arrays. Shows whether the two matrices are exactly the same. Here is a running example:
Enter list1:51 22 25 6 1 4 24 54 6
Enter list2:51 25 22 6 1 4 24 54 6
The two arrays are identical -
参考代码:
