Difference between Method Overloading and Method Overriding

Method Overloading: 

• If a class have multiple methods by same name but different parameters(method signature), it is known as Method Overloading. 
• Overloading happens at compile-time. The binding of overloaded method call to its definition has happens at compile-time.
• Static methods can overload which means that a class can have more than one static method of the same name. 
• Overloading is being done in the same class. 
• Static binding is used for overloaded methods. 
• Overloading gives better performance as compared to overriding, the reason is that the binding of overridden methods  is being done at runtime. 
• Private and final methods can be overloaded. It means a class can have more than one private or final methods of same name.
• Return type of methods doesn't matter in case of overloading, it can be same or different but argument list should be different.  
• Java Method overloading example 

                    public  class OverloadingExample {

                           public int sum (int a, int b){

                                    return a+b;

                           }

                          public int sum (int a, int b, int c){

                                     return a+b+c;

                          }

                    }

Method Overriding:

•  If a subclass (child class) has the same method as declared in the parent class, it is known as method overriding. 
• Overriding happens at runtime. The binding of overridden method call to its definition happens at runtime. 
• Static methods can't be overridden, even if you declare a same static method in child class it has nothing to do with the same method of parent class. 
• Overriding is all about  giving a specific implementation to the inherited method of parent class. 
• Dynamic binding is used for  overridden methods. 
• A child class cannot override the private and final methods of their base class. 
• Overridden methods should be more specific return type  and argument list should be same. 
• Java Method overriding example: 

                    class Animal{

                        void eat(){

                             System.out.println("Eating"); 

                          }

                    }

                    public class Cat extends Animal{

                          void eat(){

                              System.out.println("Eating Meat"); 

                           }

                    }
