How do you call multiple constructors with single object?
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 } }
What is the difference between default constructor and parameterized constructor?
A default constructor is one that has no parameters (C++ also calls constructors with all default parameters a default constructor), while a parameterized constructor is one that has at least one parameter without a default value. Default constructors can be provided by the compiler if no other constructors are defined for that class or any class the class inherits from, while parameterized constructors must always be defined by the developer.
When do you get a default constructor When the class has no other constructors When you define at least one constructor When you define a class None of the above?

Whati is Constructor overloading?
Constructor overloading is the feature by which we declare multiple constructors for a single class. 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 } }
Can constructor have one or more parameters?
Yes, a constructor can have one or more parameters. This allows for the initialization of an object with specific values at the time of its creation. By using parameters, you can create multiple instances of a class with different states based on the provided arguments. Additionally, constructors can also be overloaded, meaning you can have multiple constructors with different parameter lists in the same class.

What are different type of constructor in java?
Every class, including abstract classes, MUST have a constructor. The different types are: a. Regular constructors b. Overloaded constructors and c. Private constructors
Why you use constructors?
To create an instance of the class that implementing that constructor
When do you get a default constructor When the class has no other constructors When you define at least one constructor When you define a class None of the above?

What is the order of constructors and destructors of object?
The order of constructors is determined by the sequence they are called in the code, starting with the base class constructor and moving to the derived class constructor. Destructors are called in the reverse order of constructors, starting with the derived class destructor and moving to the base class destructor.
What is different between constructor and method?
Constructors have no return type and their names must exactly match the class name. Apart from this constructors and methods are similar to one another.

What is concession constructor?
Constructors are basically used to evoke methods of a class creating its object..and as far as i know there is no constructor called concession constructor..
Can we have more than one constructions in a class?
Yes, a class in programming can have multiple constructors, a feature known as constructor overloading. This allows a class to be instantiated in different ways, with varying parameters to initialize the object. Each constructor can have a different parameter list, enabling flexibility in object creation. However, the constructors must have distinct signatures to avoid ambiguity.
How are parametrized constructor different from non parametrized constructor?
Parameterised constructors accept arguments while non parameterised constructors do not. Example : class A { A(){ // non parameterised ... } A(int b){ // parameterised ... } }
