Java 删除String[] 数组中的多个元素

最近遇到一个问题，比较有意思的是要删除String[]中的多个元素，而要删除元素的数组是double[] 型的:

String items[] = {"1","2","3","4","5"};
double[] need_del_items =  {2,3};

完整代码：

       String items[] = {"1","2","3","4","5"};
        for(String a:items)
            System.out.println(a);      
        double[] need_del_items =  {2,3};
        
        List<String> list1=Arrays.asList(items);
        List<String> arrList = new ArrayList<String>(list1); //这句话的重要性在上一节blog中有讲到
        
        /* 主要是下面两行 */
        java.text.NumberFormat NF = java.text.NumberFormat.getInstance();
        //设置数的小数部分所允许的最小位数，避免小数位有多余的0
        NF.setMinimumFractionDigits(0);
        
        for(double a:need_del_items)
        {
                String b = NF.format(a);
                arrList.remove(b);
        }
        
        arrList.toArray();
        System.out.println(arrList);

运行结果：
