What will be the Output?

class Parent
{
   static void show()
{
System.out.println("static show in Parent");
}
   void show1()
{
System.out.println("Parent show1");
}
}

class Child extends Parent
{
   static void show()
{
System.out.println("static show in Child");
}
   void show1()
{
System.out.println("Child show1");
}
   public static void main(String rk[])
{
Parent p = new Child();
p.show();
p.show1();
}
}

Predict the output and draw a conclusion from that regarding the invocation of static and non-static methods.

  1. output:static show in Parent
    Child show1
    conclusion:static method show() in child class is overriden by the show() method in parent class:while non static method show1() in child class can't be overriden by the
    method show1() in parent class:::::: it conclude that only static method can be overriden and not the non-static methods or members.

Practice Set

1. Write a program to create a class Voter which contains attributes name, date_of_birth and voter_id and voter has a Voter_Card. Provide appropriate constructor to initialize all the attributes of the Voter but voter id must be assigned automatically only when the age of the voter is greater than or equal to 18 years. VoterCard is a nested class with attributes voter_id and Voter_name. Make sure that voter card is created only when user is a valid voter and if it is already created then must not be assigned the new voter id. 2. Write a program to define two interfaces UGC and AICTE both having a default method int getAdmission() to take the admission and an abstract method String payFee(). getAdmission() in UGC must ask the percentage in qualifying exam and if the percentage >= 60 then generate the registration number and return. getAdmission() is AICTE must ask the user to join the counseling after 5 days and display the date of counseling and return the counseling token numb
