Java中数组的地址问题(hashCode解析):
代码语言:javascript
复制import java.util.Arrays;
public class Action1 {
public static void main(String[] args) {
//1、初始数组
int [] array0= {5,9,9,9,65,65,95,9,5,6,69,6,65,899};
System.out.println("0->生成地址:t" array0.hashCode());
//2、赋值数组
int [] array1=array0;
System.out.println("1->未生成新地址:t" array1.hashCode());
//3、创建数组相当于new
int[] array2 = Arrays.copyOf(array0, array0.length);
System.out.println("2->生成新地址:t" array2.hashCode());
//4、new创建数组,相当于array2的Arrays.copyOf
int[] array3 = new int[array0.length];
for (int i = 0; i < array0.length; i ) {
array3[i]=array0[i];
}
System.out.println("3->生成新地址:t" array3.hashCode());
}
}
效果:
