java如何修复集合的compareTo方法？

1 年，3 月 Questions & Answers

然而，当我打印出布景的大小时，有128支足球队。。。我只有114分。有人能帮我修复compareTo方法来修复此错误吗。我甚至比较了多个字段，但它不能适应这个错误

这是足球课

    System.out.println(teams.size());

共 (2) 个答案

  1. # 1 楼答案

    但你只读了114行

     for(int i=0;i<114;i++)
    {
        String team=sc.nextLine();
        Integer ...

    每行没有多个团队，也没有需要解析的代码。您可以将其动态化，而不是硬编码以读取114行

  2. # 2 楼答案

    您可能希望定义一个常量（例如MAX_TEAMS=128），而不是使用整数文本。然后您可以在循环/比较中使用它

    参考循环的计划类

    for(int i=0;i<114;i++)
