Java，检查两个字符数组是否相等

Question

我在 Java 中有两个字符数组:

orig_array 和 mix_array。我需要检查它们是否不相等。

这是我到目前为止所拥有的:

sample data
orig_team=one
mix_team=neo

while(!Arrays.equals(mix_team, orig_team))
{

    if (Arrays.equals(mix_team, orig_team))
    {

        System.out.println("congradulations! you did it");
        System.exit(0);
    }

    else {

        System.out.println("enter the index");
        Scanner scn = new Scanner(System.in);
        int x = scn.nextInt();
        int y = scn.nextInt();
        char first=mix_team[x];
        char second=mix_team[y];
        mix_team[x]=second;
        mix_team[y]=first;
        for (int i = 0; i < mix_team.length; i = i + 1) 
        {
            System.out.print(i);  
            System.out.print(" ");
        }
        System.out.println();
        System.out.println(mix_team);
    }
}       

如何判断两个数组是否相等？

Answer 1

while 循环的 block 仅在两个数组不相等时执行，因此使用相同的相等性检查启动该 block 是没有意义的。换句话说，该行:

if (Arrays.equals(mix_team, orig_team))

...将始终为false。
