Inheritance, polymorphism, abstraction, encapsulation,over riding, over loading all implemented in single program. The file name must be MainClass.java Program: class One { public void display() { System.out.println("One"); } } //inheritance class Two extends One { @Override public void display() { System.out.println("Two"); } public int add(int x, int y) { return x+y; } //Overload public double add(double x,double y) { return x+y; } } //encapsulation example class EncapTest { private String name; public String getName() { return name; } public void setName(String newName) { name = newName; } } //abstraction abstract class TwoWheeler { public abstract void run(); } class Honda extends TwoWheeler{ public void run(){ System.out.println("\nbike is Running.."); } } class MainClass { public static void main(String[] args) { One a=new One(); a.display(); Two b=new Two(); b.display(); System.out.println(b.add(4,2)); System.out.println(b.add(5.,2.)); //polymorphism EncapTest encap = new EncapTest(); encap.setName("Sandeep's"); System.out.print("Name : " + encap.getName() ); TwoWheeler test = new Honda(); test.run(); } } Output: One Two 6 7.0 Name : Sandeep's bike is Running.
