overriding methods java code example
Example 1: what is method overloading and method overriding 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.
Method overriding means defining a method in a child class that is already defined in the parent class with the same method signature, same name, arguments, and return type

}
}
class Dog extends Animal {
public void move() {
System.out.println("Dogs can walk and run");
}
}
public class TestDog {
public static void main(String args[]) {
Animal a = new Animal();
Animal b = new Dog();
a.move();
b.move();
}
}
