在java中比较数组 [英] comparing arrays in java

问题描述

int [] nir1 = new int [2];
nir1[1] = 1;
nir1[0] = 0;


int [] nir2 = new int [2];
nir2[1] = 1;
nir2[0] = 0;

boolean t = nir1.equals(nir2);
boolean m = nir1.toString().equals(nir2.toString());

为什么两个M和T假的？什么是Java中比较2阵列的正确方法？

Why are both m and t false? What is the correct way to compare 2 arrays in Java?

推荐答案

使用<一个href=\"http://download.oracle.com/javase/6/docs/api/java/util/Arrays.html#equals%28int%5B%5D,%20int%5B%5D%29\">Arrays.equals方法。例如：

boolean b = Arrays.equals(nir1, nir2); //prints true in this case
