Java Constructor Overloading

Question

I\'m new with Java and I\'m having trouble understanding the constructor issue, I have looked at many tutorials and still I\'m having difficult to understand why we use construc

Answer 1

a) is it because the constructors have to be with the same name as the class and we need to distinguish between them ?

Yes constructors are always the name of the class without any return type, and in order to distinguish between them, you can have different parameters.

b) what if i want to add a third constructor ? it can be also int type ?

Yes, you can add any no. of overloaded constructors but those all should be different in no. and/or type of parameters.

Like :-

public User() // default constructor
{
}

public User(int age) // overloaded constructor with int
{
}

public User(String name) // // overloaded constructor with String
{
}

public User(String name, int age) // // overloaded constructor with String and int
{
}
