overriding in java

Overriding means same method name and same parameter, 
occur in different class that has 
inheritance relationship. 
we use method overriding to implement 
specific functionality to the method. 

Examples are get and navigate methods
of different drivers in Selenium .

Example: get method
WebDriver driver = new ChromeDriver();
driver.get("URL") ==> opens the url from chrome

WebDriver driver = new FireFoxDriver();
driver.get("URL") ==> opens the url from Firefox

we can only override instance methods and method override 
takes place in sub class.
instance method that we are going to override cannot be private and final
Example: get method
WebDriver driver = new ChromeDriver();
driver.get("URL") ==> opens the url from chrome

WebDriver driver = new FireFoxDriver();
driver.get("URL") ==> opens the url from Firefox

we can only override instance methods and method override 
takes place in sub class.

override cannot be private and final

method overloading

Method overloading is providing two separate methods in a class 
with the same name but different arguments, while the method return type 
may or may not be different, which allows us to reuse the same method name.

// Java program to demonstrate working of method
// overloading in Java. 
  
public class Sum { 
  
    // Overloaded sum(). This sum takes two int parameters 
    public int sum(int x, int y) 
    { 
        return (x + y); 
    } 
  
    // Overloaded sum(). This sum takes three int parameters 
    public int sum(int x, int y, int z) 
    { 
        return (x + y + z); 
    } 
  
    // Overloaded sum(). This sum takes two double parameters 
    public double sum(double x, double y) 
    { 
        return (x + y); 
    } 
  
    // Driver code 
    public static void main(String args[]) 
    { 
        Sum s = new Sum(); 
        System.out.println(s.sum(10, 20)); 
        System.out.println(s.sum(10, 20, 30)); 
        System.out.println(s.sum(10.5, 20.5)); 
    } 
}

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 
Method overloading is providing two separate methods in a class 
with the same name but different arguments, while the method return type 
may or may not be different, which allows us to reuse the same method name.
1) Method Overloading occurs with in the same
class
2) Since it involves with only one class inheritance
is not involved.
3)In overloading return type need not be the same 
4) Parameters must be different when we do
overloading
5) Static polymorphism can be acheived using
method overloading
6) In overloading one method can’t hide the
another

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);
}
