尝试在switch语句中使用类

public class MyClass {
    private int value;

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

    @Override
    public boolean equals(Object obj) {
        if (this == obj) {
            return true;
        }
        if (obj == null || getClass() != obj.getClass()) {
            return false;
        }
        MyClass myClass = (MyClass) obj;
        return value == myClass.value;
    }

    public static void main(String[] args) {
        MyClass obj1 = new MyClass(1);
        MyClass obj2 = new MyClass(2);

        switch (obj1) {
            case obj1:
                System.out.println("obj1");
                break;
            case obj2:
                System.out.println("obj2");
                break;
            default:
                System.out.println("default");
                break;
        }
    }
}
