How do you call multiple constructors with single object?

Answer 1

You can have any number of constructors for a class. All we need to do is implement constructor overloading.

Ex: let us say we want to create multiple constructor for a class Test

Public class Test {

Public Test() {

//code

}

Public Test(int vals) {

//code

}

Public Test(String val) {

//code

}

}

Answer 2

Multiple constructors are overloaded versions of the class constructor. They are chosen based on their argument types.

The default constructor takes no arguments.

The copy constructor takes one argument of reference type to a const variable of the class.

The conversion constructor takes one argument of different type than the copy constructor.

Other constructors take two or more arguments and can be used for special initialization. Often, these other constructors can be built as one, using default values for arguments so, for instance, one of them could function as the default constructor if needed.

Answer 3

To give multiple options of how you can create an object of the current class

Answer 4

Derive the object from multiple classes.
