• Overloading :(same function name but different signature)
  1. Two or more methods having the same name with different arugment in same class is known as Overloading.
  2. Overloading is used when you want to extend the functionlity.
  3. Overloading is known as compile time polymorphism

  Overriding :(same function name but same signature)
  1. Two or more methods having the same method name and same arugment in parent class and child class in known as overriding.
  2. Overriding is used when you want to reuse the existing functionlity.
  3. Overriding is known as run time polymorphism

• 1)method overloading :  Two or more methods having the same name with different arugment in same class is known as Overloading.
  eg: public class Line {

           void draw(int x1, int y1, int x2, int y2) {
          // draws the line with integer coordinates
      }

           void draw(float x1, float y1, float x2, float y2) {
          // draws the line with real coordinates
      }
  }

  2)method overriding:  Two or more methods having the same method name and same arugment in parent class and child class in known as overriding.
  eg: class Animal
  {
  public void move() {
  System.out.println("Animals can move");
  }
  }
  class Dog extends Animal
  {
  public void move()
  {
  System.out.println("Dogs can walk and run"); }
  public void bark() {
  System.out.println("Dogs can bark"); }
  }
  public class TestDog {
  public static void main(String args[]) {
  Animal a = new Animal(); // Animal reference and object Animal b = new Dog(); // Animal reference but Dog object a.move(); // runs the method in Animal class b.move(); // runs the method in Dog class b.bark();
  }
  }

• same class with the same name overloading...........overriding means having two methods with the same arguments, but different implementation

  ---

• 1.Overloading -- two or more methods having same name but different number of parameters or different types of parameters is called method overloading .It is known as compile time polymorphism. 2.Overriding -- two or more method having the same number of argument and same type of argument and define defined in child class as well as parent class is called as method overriding. It is also called runtime polymorphism.

• overloading same function name but different signature. overriding same function name but same signature

  ---

• Overloading:
  Two or more method having same name but different argument in same class is known as overloading.
  overloading is:1.The change in the number of parameters that are accepted
  2.he change in the type of the method parameters that are accepted
  3. The change in the positions of the parameters that are accepted
  4.compile time polymorphism
  Overriding:
  Two or more method having the same method name and same argument but different class is known as overriding.it is also kown as run time polymorphism,dynamic polymorphism,dynamic binding.

• Overloading:-1) Different no of parameters 2) Overloading known as compile time polymorphism Overloading:-1) same no of parameters 2) it is run time

  ---

• Method Overloading- 1)Performed within class. 2) parameters must be different. 3) example- compile time polymorphism. Method Overriding- 1)Performed in 2 classes having inheritance. 2) parameters must be same. 3) example- run time polymorphism

• Overloading done at compile time and Overrinding done at runtime.

  ---

• overloading is being done in the same class while for overriding base and child classes are required. Overriding is all about giving a specific implementation to the inherited method of parent class.

  ---

• Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding means having two methods with the same method name and parameters (i.e., method signature). One of the methods is in the parent class and the other is in the child class.

• overloading:- overloading is the method where two or more method in same class with different argument it is called overlooding overridding:- overriding is the method where two or more method in same class with same argument it is called overridding

• Overloading is a compile time polymorphism and overriding is a run time polymorphism.

• overloading is compile time polymorphism and overriding is run time polymorphism if functions name are same and parameters are different , according to parameters functions are differential to each other , all functions are contained in same class knows as function overloading if functions name and parameters are same but functions contain in different classes , knows as overriding

• Overloading concept is in polymorphism and overriding in inheritance Overloading is when a class contains more than one function of same name along with different arguments And overriding is when an object contains reference of more than one function having same name along with same arguments

  ---

• Overloading means same function name but different in signature.for e.g.,we may have the same function name call area(),but code written in this function may differ. Overriding means the same function name with same signature.In this case we cannot change the code inside of that function.

  ---

• overloading is also known as compile time polymorphism. In which the value will not change at run time. overriding is also known as run time polymorphism. In which the value will change at run time.

• Imagine you have a goods carrying vehicle that will only transport boxes as doTransport(Package package) method in a Transport Vehicle class If you get a new requirement to transport liquid containers, then the doTransport can be overloaded as doTransport (Package package, Container container) [Assume Package and Container classes are two different entities]. Now Imagine they want to transport xyz of Misc type, then a new method can be added as doTransport (Package package, Container container, Misc miscItem) or doTransport (Package package, Misc miscItem) or doTransport (Misc miscItem) as per your requirement. The above concept is overloading, we have modified the method to make it feasible and usable based on the inputs. A must thing for overloading is the Arguments must change, they method can become no-arg method or var-args method, it doesn't matter. The arguments must change and along with it, return type can change. So TransportVehicle class will have more than one method with same name and different arguments. Overriding is the concept in which inheriting Class can change the implementation of the parent class's method. if a new class ElectricTransportVehicle is inherited from TransportVehicle, then the doTransport method can be overridden to have a different implementation like -> check if the Package or Container or Misc is conductive -> check if they spills -> check if there are leaks to prevent Short Circuit or Electric mishaps. Assume our vehicle is a high Voltage operated vehicle with overhead electric lines or something similar. The method arguments shouldn't change else it will become overloading, not overriding. there are also other rules which requires a deep dive into internals. Finally #Overriding is implementing our own version of a inherited method without changing method skeleton #Overloading is implementing a different version of method in same class with mandatory change in the arguments.

• overloading
  method names are same but signatures are different. you can define more than one method with same name but there signature must be different.
  overriding
  when we define or re-define methods of parent class or intefaces then we must use the same method name and signature which were present in parent class.
