Answer 1

Constructor Overloading is a technique in Java in which a class can have any number of constructors.

public class Demo
{ 
public Demo()           
                {   
System.out.println("Welcome to the java"); 
 } 
public Demo(String Hello)       
        { 
  System.out.println("I am " + Hello); 
}
  public Demo(String Hello, int Weight) 
    {   
 System.out.println("My name is " + Hello + " and I weigh " + Weight); 
 }
  public static void main(String args[]) 
 { 
Demo A = new Demo();     
Demo B = new Demo("A weapon");   
Demo C = new Demo("John cena", 396);    
  }
}
