Java PairT,N 类实现[关闭]

使用Java编程语言进行开发时，经常会遇到需要将两个相关的对象绑定在一起的情况。为了解决这个问题，Java提供了一个Pair类。Pair类是一个泛型类，可以让我们将两个不同类型的对象绑定在一起。

java
public class Pair {
    private T first;
    private N second;
    public Pair(T first, N second) {
        this.first = first;
        this.second = second;
    }
    public T getFirst() {
        return first;
    }
    public N getSecond() {
        return second;
    }
    public void setFirst(T first) {
        this.first = first;
    }
    public void setSecond(N second) {
        this.second = second;
    }
}

java
public class Person {
    private String name;
    private int age;
    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }
    public String getName() {
        return name;
    }
    public int getAge() {
        return age;
    }
    public void setName(String name) {
        this.name = name;
    }
    public void setAge(int age) {
        this.age = age;
    }
}
public class Main {
    public static void main(String[] args) {
        Pair personPair = new Pair<>("John", 25);
        Pair personAgePair = new Pair<>(new Person("Alice", 30), 40);
        String name = personPair.getFirst();
        int age = personPair.getSecond();
        System.out.println("Name: " + name + ", Age: " + age);
        Person person = personAgePair.getFirst();
        int personAge = personAgePair.getSecond();
        System.out.println("Person: " + person.getName() + ", Age: " + personAge);
    }
}
