Inheritance in Java

Inheritance is one of the feature of Object-Oriented Programming . Inheritance allows a class to use the properties and methods of another class. When a class "ABC" can access 
the properties and method of a class "XYZ" then the "XYZ" class is called "Parent/Super" class and the "ABC" class is called "Sub/Derived" class . Syntax is 
  
class XYZ{
      //  write your logic here
   }

 class ABC extends XYZ{
    // write  your logic here
}

Example :

class A
 {
    int x;

     public void display()
     {
          System.out.println("Value of X is :"+x);
     }
}

public class B extends A{
 
  public static void main(String []args)
  {
     A obj=new A();
     obj.x=10;
     obj.display();
  }
}

Output :  
            Value of X is :10
