如何使用默认访问修饰符创建构造函数是参数化构造函数的类的对象

Question

I am working enhancement project.
Here they created some classes using parameterized constructor using default access modifier. I want to create those classes object and use the methods for call business functionalities. packages are different.

public class CheckAmount {

    private double balance;

    CheckAmount(double balance){
        this.balance = balance;
    }
    .....
}

so how to create the object of classes. Please provide different approches.. if possible. Thanks

Answer 1

Default access means that access is allowed within same package. So you need the public modifier. Another possibility is to introduce an indirection like a factory and dependency injection, but this is more advanced.
