Constructor
Constructor is a particular member of the specified class which is used to initialize the state of an object. It gives the values to the data members on the time of object creation that’s the reason it is named constructor.
It does not have any explicit return type but it returns current instance of the specified class.
Example
public class Main { Main(){} public static final void main(String[] args) { Main obj1 = new Main(); System.out.println(obj1 instanceof Main); } } |
Output
true |
