如何在Java的列表数组中存储三个不同的对象 [英] How do you store three different objects in a list array in Java

问题描述

我需要在Java中创建一个列表数组，该列表数组可以容纳三个不同的对象(姓，名，结果)，并且想知道如何做到这一点

I need to create a list array in java that can hold three different objects (Surname, forename, Result) and was wondering how to do that

推荐答案

最好也是面向对象的方法是创建一个具有姓，名和结果作为属性(实例变量)的类，如下所示:

The best and also Object Oriented approach is to Create a class with surname, forename and result as attributes(instance variables) like below:

class Student{
private String surname;
private String forename;
private String result;
public Details(String surname, String forename, String res){
   //initialize properties here
  }
}

现在，创建一个仅接受Student对象的列表.

now, create a List which only accepts Student Object.

List<Student> list = new ArrayList<Student>();
list.add(new Student("surname", "forname", "pass"));
