# Inheritance

### Java Inheritance:

* **Definition:**
  * Inheritance is an Object-Oriented Programming (OOP) concept that allows creating a new class (subclass) from an existing class (superclass).
* **Syntax:**

  ```java
  class Subclass extends Superclass {
      // fields and methods of Subclass
  }
  ```
* **Example:**

  ```java
  class Animal {
      String name;
      public void eat() {
          System.out.println("I can eat");
      }
  }

  class Dog extends Animal {
      public void display() {
          System.out.println("My name is " + name);
      }
  }

  class Main {
      public static void main(String[] args) {
          Dog labrador = new Dog();
          labrador.name = "Rohu";
          labrador.display();
          labrador.eat();
      }
  }
  /*
  Output:
  My name is Rohu
  I can eat
  */
  ```
* **Inheritance Types:**
  1. **Single Inheritance:**
     * One subclass extends one superclass.
     * Example: `Class A extends Class B`.
  2. **Multilevel Inheritance:**
     * Subclass extends another subclass, creating a chain.
     * Example: `Class B extends Class A` and `Class C extends Class B`.
  3. **Hierarchical Inheritance:**
     * Multiple subclasses extend a single superclass.
     * Example: `Class B extends Class A` and `Class C extends Class A`.
  4. **Multiple Inheritance:**
     * One subclass extends multiple superclasses.
     * Note: Java does not support multiple inheritance directly.
  5. **Hybrid Inheritance:**
     * Combination of two or more types of inheritance.
