java 分割字符串后放入List中

public static void main(String[] args) {
        String str="单机游戏,网络游戏,小游戏";
        List<String> list=new ArrayList<String>();
        StringTokenizer st=new StringTokenizer(str,",");
        while(st.hasMoreTokens()){
            list.add(st.nextToken());
        }

        for(String s:list){
            System.out.println(s);
        }
    }
