如何返回我用来调用方法的对象？

public class MyClass {
    private int value;

    public void setValue(int value) {
        this.value = value;
    }

    public int getValue() {
        return this.value;
    }
}

class MyClass:
    def __init__(self, value):
        self.value = value

    def get_value(self):
        return self.value

my_object = MyClass(10)
print(my_object.get_value())

function MyClass(value) {
    this.value = value;
}

MyClass.prototype.getValue = function() {
    return this.value;
};

var myObject = new MyClass(10);
console.log(myObject.getValue());
