如何调用私有方法并传递参数

import java.lang.reflect.Method;

public class MyClass {
    private void privateMethod(String param) {
        System.out.println("Private method called with parameter: " + param);
    }

    public static void main(String[] args) throws Exception {
        MyClass obj = new MyClass();
        Method method = MyClass.class.getDeclaredMethod("privateMethod", String.class);
        method.setAccessible(true);
        method.invoke(obj, "Hello");
    }
}

class MyClass:
    def __private_method(self, param):
        print("Private method called with parameter:", param)

obj = MyClass()
private_method = getattr(obj, "_MyClass__private_method")
private_method("Hello")

function MyClass() {
    var privateMethod = function(param) {
        console.log("Private method called with parameter: " + param);
    };

    return {
        publicMethod: function(param) {
            privateMethod(param);
        }
    };
}

var obj = MyClass();
obj.publicMethod("Hello");
