经经常使用到,有时候不仅仅是简单的基本类型,那种能够用set集合去重,好多时间用到的是我们自己定义的类型,以下举个样例(我这儿就那int举例了): 方法一. 这样的类似与选择排序算法,首先我们取i值,然后将i之后的全部反复的去掉.详细实现例如以下: import java.util.List; import java.util.concurrent.CopyOnWriteArrayList; /** * 创建时间:2014-11-18 下午3:26:35 * * @author zhangtia…

一.源码 public class Test1 { public static void main(String[] args) { // Student[] arrs = new Student[] { new Student() { id = "22" } }; C# 可以简写法,Java不支持 Student[] arrs = new Student[1]; Student st = new Student(); st.id = 12; st.name = "qwe&q…
