java数组去掉重复数！

import java.util.ArrayList;

public class Try {

/**
* @param args
*/
    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)); 

}
}
