如何檢查兩個數組是否相等？

解決方法

下麵的示例演示如何使用數組的equals()方法來檢查兩個數組相等與否。

import java.util.Arrays;

public class Main {
   public static void main(String[] args) throws Exception {
      int[] ary = {1,2,3,4,5,6};
      int[] ary1 = {1,2,3,4,5,6};
      int[] ary2 = {1,2,3,4};
      System.out.println("Is array 1 equal to array 2?? "
      +Arrays.equals(ary, ary1));
      System.out.println("Is array 1 equal to array 3?? "
      +Arrays.equals(ary, ary2));
   }
}

結果

上麵的代碼示例將產生以下結果。

Is array 1 equal to array 2?? true
Is array 1 equal to array 3?? false
