what is overloading in java

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.
instance method that we are going to
override cannot be private and final

//https://www.geeksforgeeks.org/overloading-in-java/ // 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)); } }

/*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"); } }
