实现可比较类的泛型类

// 定义一个泛型类，类型参数T必须实现Comparable接口
public class GenericClass<T extends Comparable<T>> {
    private T data;

    // 构造函数
    public GenericClass(T data) {
        this.data = data;
    }

    // 获取数据
    public T getData() {
        return data;
    }

    // 设置数据
    public void setData(T data) {
        this.data = data;
    }

    // 比较两个对象
    public int compareTo(GenericClass<T> other) {
        return this.data.compareTo(other.data);
    }

    public static void main(String[] args) {
        // 创建两个GenericClass实例，类型参数为Integer
        GenericClass<Integer> obj1 = new GenericClass<>(10);
        GenericClass<Integer> obj2 = new GenericClass<>(20);

        // 比较两个对象
        int result = obj1.compareTo(obj2);
        if (result < 0) {
            System.out.println("obj1 is less than obj2");
        } else if (result > 0) {
            System.out.println("obj1 is greater than obj2");
        } else {
            System.out.println("obj1 is equal to obj2");
        }
    }
}

public class MyComparableClass implements Comparable<MyComparableClass> {
    private int value;

    public MyComparableClass(int value) {
        this.value = value;
    }

    @Override
    public int compareTo(MyComparableClass other) {
        return Integer.compare(this.value, other.value);
    }
}
