Java Method Overriding

class Animal {
   public void displayInfo() {
      System.out.println("I am an animal.");
   }
}

class Dog extends Animal {
   @Override
   public void displayInfo() {
      System.out.println("I am a dog.");
   }
}

class Main {
   public static void main(String[] args) {
      Dog d1 = new Dog();
      d1.displayInfo();
   }

method overloading in java

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.
In my framework==
I use implicit wait in Selenium. Implicit wait
is an example of overloading. In Implicit wait
we use different time stamps such as SECONDS, MINUTES, HOURS etc.,
A class having multiple methods with
same name but different parameters 
is called Method Overloading

Method Overriding in java

public class Multi{ //Super class
public void multi(){
………………
}
}
 
Public class Multiplication extends Multi(){
Public void multi(){
………..
}
Public static void main(String args[]){
Multi multiplication = new Multiplication(); //Polimorphism is applied
multiplication.multi(); // It calls the Sub class add() method
}
}

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

Java Method Overloading

static int plusMethodInt(int x, int y) {
  return x + y;
}

static double plusMethodDouble(double x, double y) {
  return x + y;
}

public static void main(String[] args) {
  int myNum1 = plusMethodInt(8, 5);
  double myNum2 = plusMethodDouble(4.3, 6.26);
  System.out.println("int: " + myNum1);
  System.out.println("double: " + myNum2);

Method 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));
    }

what is method 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.
