Question

If we have class A & B, and class A’s constructor is private, and we want to use an instance of A in B, how to do that ? I see an answer that says “provide a static method or variable that allows access to an instance created from within the class ” but I didn’t understand that.

Answer 1

A needs to have a public method that provides an instance of the class A, eg:

class A {
  /*Constructors and other methods omitted*/
  public static A getInstance() {
    return new A();
  }
}
