Answers for "method overloading java"

method overriding java

Method Overloading: 
Access modifier can be same or different, 
Return-Type can be same or different, 
Parameters MUST be different, Method name MUST be same, 
any method can be overloaded

Method Overriding:
After a method is inherited it is possible to change 
the implantation of the method in the child class. 
This concept is called overriding. 
Method name, Parameter, and Return-Type MUST be same
access modifier MUST be same or more visible, 
MUST happen in the sub class, 
ONLY the instance methods can be overridden
@Override annotation MUST be applicable. 
Static and Constructor cannot be override.
We can use the @Override annotation before the method 
to declare the overriding.
EXAMPLE: get method WebDriver driver = new ChromeDriver(); 
driver.get("URL") ==> opens the url from chrome

method overloading in java

/*A class having multiple methods with
same name but different parameters 
is called Method Overloading*/

public class Names{
	static void name(String fname,String lname){
		System.out.println("My firstname is "+fname+" and lastname is "+lname);
	}
	static void name(String fname,String mname,String lname){
		
		System.out.println("My firstname name is "+fname+" and middlename is "+mname+" and lastname is "+lname);
	}
	public static void main(String[] args){
		Names.name("Khubaib","Ahmed");
		Names.name("Khubaib","Imtiaz","Ahmed");
	}
}

Method overloading in Java

public void Square ( int number ) 
{
 int square = number * number;
 System.out.printIn(“Method with Integer Argument Called:“+square);
 }
public void Square(double number)
 {
 double square = number * number; 
System.out.printIn(“Method with double Argument Called:“+square);
}
public void Square(long number)
 { 
long square = number * number;
System.out.printIn(“Method with long Argument Called:“+square);
}

java overloading

class CalculateSquare
 { 
public void square()
 { 
System.out.println("No Parameter Method Called");
 } 
public int square( int number )
 {
int square = number * number;
System.out.println("Method with Integer Argument Called:"+square); 
}
public float square( float number ) 
{
 float square = number * number;
 System.out.println("Method with float Argument Called:"+square); 
}
public static void main(String[] args)
  {
    CalculateSquare obj = new CalculateSquare();
    obj.square();
    obj.square(5);   
    obj.square(2.5);
