使用自定义类的实例对数组进行排序

import java.util.Arrays;
import java.util.Comparator;

public class CustomSort {
    public static void main(String[] args) {
        // 创建一个自定义类的实例数组
        MyClass[] myArray = new MyClass[5];
        myArray[0] = new MyClass("Alice", 25);
        myArray[1] = new MyClass("Bob", 30);
        myArray[2] = new MyClass("Charlie", 20);
        myArray[3] = new MyClass("David", 28);
        myArray[4] = new MyClass("Eva", 22);

        // 使用自定义类的实例对数组进行排序
        Arrays.sort(myArray, new Comparator<MyClass>() {
            @Override
            public int compare(MyClass o1, MyClass o2) {
                return o1.getAge() - o2.getAge();
            }
        });

        // 打印排序后的数组
        for (MyClass obj : myArray) {
            System.out.println(obj.getName() + " - " + obj.getAge());
        }
    }
}

class MyClass {
    private String name;
    private int age;

    public MyClass(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public String getName() {
        return name;
    }
