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：

1
2
3
4
5
[1, 4, 5]
