java处理超级

Question

我不完全理解这个话题以及它是如何运作的。我写了一个代码示例，它看起来正确吗？因为当我运行它时，它不断地给我错误

class team {
    public team(String[] name, String[] lastname, int year) {
    private String[] name;
    private String[] lastname;
    private int[] year;
}

public class Player extends team {
    Patrolman(String first, String last, int y){
        super(first,last,y);
        name first = new name{Road};
        lastname last = new lastname{Runner};
        year y = new year{5};
}

Answer 1

由于不知道您会遇到什么错误，我猜这是由于Player类中的Patrolman构造函数造成的

试试这个

public class Team {
   private String[] name;
   private String[] lastname;
   private int[] year;

   public Team(String first, String last, String y) {
      name = first.getBytes();
      lastname = last.getBytes();
      year = y.getBytes();
   }
}

public class Player extends Team {
    Player(String first, String last, int y) {
        super(first,last,y);
    }
}

由于您将first、last和y传递到super中，您可能不需要在Player构造函数中对它们执行任何操作
