 ### Type of Inheritance
 
-* Single inheritance
+## 1. Single Inheritance
 
-    When a child inherits properties from a single parent
-
-* Multiple inheritance
-
-    When a child inherits its properties from two or more parents.
-
-* Hierarchical inheritance
-
-    When multiple children inherit properties from a parent
-
-* Multilevel inheritance
-
-    When a parent properties are inherited by a child which again get interited by another child. For example, B is inherited from A and C is inherited from B. 
-
-    A -> B -> C
-* Hybrid inheritance
-
-    Hybrid inheritance is a combination or two or more inheritance types.

+## 2. Hierarchical inheritance
+
+When multiple children inherit properties from a parent
+
+Below is an example of hierarchical inheritance
+
+```java
+
+class A {
+	public void print_A() 
+  { 
+    System.out.println("Class A"); 
+  }
+}
+
+class B extends A {
+	public void print_B() 
+  { 
+    System.out.println("Class B");
+  }
+}
+
+class C extends A {
+	public void print_C() 
+  {
+    System.out.println("Class C");
+  }
+}
+
+class D extends A {
+	public void print_D() 
+  {
+    System.out.println("Class D");
+  }
+}
+
+public class Test {
+	public static void main(String[] args)
+	{
+		B obj_B = new B();
+		obj_B.print_A();
+		obj_B.print_B();
+
+		C obj_C = new C();
+		obj_C.print_A();
+		obj_C.print_C();
+
+		D obj_D = new D();
+		obj_D.print_A();
+		obj_D.print_D();
+	}
+}
+
+```
+
+## 3. Multilevel inheritance
+
+When a parent properties are inherited by a child which again get interited by another child. For example, B is inherited from A and C is inherited from B. 
+
+A -> B -> C
+
+```java
+
+class A {
+	public void printA()
+	{
+		System.out.println("Class A");
+	}
+}
+
+class two extends one {
+	public void printB() 
+  { 
+    System.out.println("Class B"); 
+  }
+}
+
+class three extends two {
+	public void printC()
+	{
+		System.out.println("Class C");
+	}
+}
+
+// Drived class
+public class Main {
+	public static void main(String[] args)
+	{
+		three g = new three();
+		g.printA();
+		g.printB();
+		g.printC();
+	}
+}
+
+```
+
+## 4. Multiple inheritance
+
+When a child inherits its properties from two or more parents. It can be done by the help of Interface.
+
+Below is an example of multiple inheritance.
+
+```java
+
+interface one {
+	public void printA();
+}
+
+interface two {
+	public void printB();
+}
+
+interface three extends one, two {
+	public void printC();
+}
+class child implements three {
+	public void printA()
+	{
+		System.out.println("Interface");
+	}
+
+	public void printB() 
+  { 
+    System.out.println("Class B"); 
+  }
+
+  public void printC() 
+  { 
+    System.out.println("Class C"); 
+  }
+}
+
+public class Main {
+	public static void main(String[] args)
+	{
+		child c = new child();
+		c.printA();
+		c.printB();
+		c.printC();
+	}
+}
+
+```
+
+
+## 5. Hybrid inheritance
+
+  Hybrid inheritance is a combination or two or more inheritance types.
+
+  Below is the example of hybrid inheritance.
+
+  ```java
+
+public class ClassA 
+{
+
+}
+public class ClassB extends ClassA
+{
+
+}
+public class ClassC extends ClassA 
+{
+
+}
+public class ClassD extends ClassB 
+{
+
+}
+
+  ```
