+
+In this tutorial, we will see the method overriding in Java.
+
+When **a child class provides a specific implementation for the method already declared in parent class**, it is called a method overriding.
+
+So both parent class and child class will have the same method but with different implementation.
+
+Example:-
+
+```java
+/**
+ * A Java Program to explain method oeverriding.
+ * @author coderolls.com
+ *
+ */
+public class Test {
+	public static void main(String[] args) {
+        Dog dog = new Dog();
+        Cat cat = new Cat();
+
+        dog.printSound();
+        cat.printSound();
+    }
+
+}
+class Animal {
+
+    public void printSound() {
+        System.out.println("Print sound of animal");
+    }
+}
+
+class Dog extends Animal {
+	
+    @Override
+    public void printSound() {
+        System.out.println("Dogs bark..!");
+    }
+}
+
+class Cat extends Animal {
+	
+    @Override
+    public void printSound() {
+        System.out.println("Cats meow..!");
+    }
+}
+```
+
+1. In above example `Animal` is the parent class. It has `printSound()` method with it's own implementation.
+2. Next, we have created a child class `Dog` by extending the parent class `Animal`. We know dogs do bark so we can provide specific implementation for the  `printSound()` method in `Dog` class.
+3. Also, we have created a child class `Cat` by extending the parent class `Animal`. We can again provide cat specific implementation for the  `printSound()` method in `Cat` class.
+4. In Test class, we have created objects of Dog and Cat class and invoked their `printSound()` method. We can see, when we invoke the  `printSound()` method on Dog obejct `d`og, it is printing the `Dogs bark..!` i.e. dog specific implementation. And when we invoke the  `printSound()` method on Cat obejct `cat`, it is printing the `Cats meow..!` i.e. dog specific implementation
