java与js给数组去掉重复字符串

我在去重之前首先是将原有数组进行排序，然后再进行去重操作。

1.java去重代码：

　　

public static void main(String[] args) {
		String []str=new String[]{"123","abc","sdfadf","123","3434","abc","87878","123","sss","sss","ssssssssss"};
		String Str2="";
		Arrays.sort(str);//排序方法
		for(int i=0;i<str.length-1;i++){
			System.out.println("str=="+str[i]);
			if(str[i]==str[i+1]){
				//i++;
				continue;
			}
			Str2+=str[i]+",";
		}
		Str2+=str[str.length-1];
		System.out.println(Str2);
		//System.out.println(Str2.indexOf("123"));
	}

２.js去重代码：

<script type="text/javascript">
    $(function(){
        var str=["aaa","aaa","ccc","aaa","bbb","ddd",1212,999,77,1212];
        var Str2="";
                str=str.sort();//排序方法
            alert('去重前：'+str);
           
           for(var i=0;i<str.length-1;i++){
               //alert(members[i]);
               if(str[i]==str[i+1]){
                //i++;
                 continue;
              }
               Str2+=str[i]+",";
           }
           Str2+=str[str.length-1];
           alert('去重后：'+Str2);
        
    });
 
 
  </script>
