Java中Arrays類別的兩個方法：deepEquals和equals

deepEquals和equals是Java中Arrays類別的兩個靜態方法，可是它們之間有什麼樣的區別呢?

代碼一、

import java.util.Arrays;public class Test {	public static void main(String[] args) {		String[][] name1 = {{ "G","a","o" },{ "H","u","a","n"},{ "j","i","e"}};		String[][] name2 = {{ "G","a","o" },{ "H","u","a","n"},{ "j","i","e"}};		System.out.println(Arrays.equals(name1, name2));    // false		System.out.println(Arrays.deepEquals(name1, name2));// true	}}

代碼二、

import java.util.Arrays;public class Test {	public static void main(String[] args) {		String[] name1 = {"G","a","o","H","u","a","n","j","i","e"};		String[] name2 = {"G","a","o","H","u","a","n","j","i","e"};		System.out.println(Arrays.equals(name1, name2));      // true		System.out.println(Arrays.deepEquals(name1, name2));  // true	}}

總結：

代碼二、

用1於判定兩個指定數組彼此是否深層相等，此方法適用於任意深度的嵌套數組。

2、equals用於判定兩個數組是否相等，如果兩個數組以相同順序包含相同元素，則傳回true，否則傳回false。

3、透過比對「代碼一」和「代碼二」我們可以得出這樣一個結論：如果兩個數組使用equals返回true，則使用deepEquals也傳回true，也就是說在比較的兩個數組均在一維數組的前提下，equals和deepEquals的比較結果沒有差別；

4、如果要比較多為數組，則需要使用deepEquals方法；
