字符串数组(String []) 去掉重复值的方法

import java.util.ArrayList;

public class Try {

/**?
* @去掉重复值
*/?
??? public static void main(String[] args) {?
??? String test="100,120,166,1555,120,150,100";?
???????? String[] test1=test.split(",");?
???????? ArrayList list=new ArrayList();?
??????? for(int i=0;i<test1.length;i++)???
?????? ?{?
???????????? if(!list.contains(test1[i]))?
??????????? ?list.add(test1[i]);???????
?????????}?

???????? System.out.println("hehe"+list.size()+"haha");??
???????? for(int i=0;i<list.size();i++)?
???????? System.out.println("hehe"+list.get(i));?

}?
}

这个方法是很好,但是还有更加简单的

?

String[]?s?=?request.getParameterValues("noattRid");
List?list?=?Arrays.asList(s);
Set?set?=?new?HashSet(list);

String []?rid=(String?[])set.toArray(new String[0]);
