利用instanceof操作符判断Java数组的类型

public class Test
{
    public static void main(String[] args)
    {
        int[] a = new int[4];
        int[] b = new int[4];
        int[] c = a;
        int[][][] d = new int[2][3][4];

        System.out.println(a instanceof Object);
        System.out.println(a instanceof int[]);
        System.out.println(d[0] instanceof int[][]);
        System.out.println(d[0][2] instanceof int[]);

        System.out.println(a.equals(b));
        System.out.println(a.equals(c));
    }
}

public class Test 
{
	public static void main(String[] args)
	{
		int[] a = new int[4];
		int[] b = new int[4];
		int[] c = a;
		int[][][] d = new int[2][3][4];
		
		System.out.println(a instanceof Object);
		System.out.println(a instanceof int[]);
		System.out.println(d[0] instanceof int[][]);
		System.out.println(d[0][2] instanceof int[]);
		
		System.out.println(a.equals(b));
		System.out.println(a.equals(c));
	}
}

 

 

输出结果为：

true
true
true
true
false
true
