How to pass a class name to the constructor of another class?

user543623Jul 22 2023

Hello,

How to pass a class name to the constructor of another class?

I have three classes below: A, B, and Main. I would like the Class A constructor to accept a class name as a parameter. When I create an object of class A, I should be able to pass the name of the actual class (B, in this case). Then, obj should be able to access the methods of class B.

How can I achieve it? Thank you!

class A{

// constructor with param
A( "add param here"){

}

// Add getter method

public className getClassName(){

return className;

}

}

class B{

// method 1

// method 2

}

class Main{

A obj = new A("B");

// obj.method1();
// obj.method2();

}
