Create an abstract class called Plan, which comprises of a data member called ‘rate’ of type double, one member method called getRate(), which is to be implemented, and another member method called calculateBill(int units), which takes a parameter called ‘units’ of type integer. The calculateBill(int units) method will display the total amount of bill.



package javaapplication24;

abstract class plan {

        public double rate;
        abstract public void getrate();
        double b;

        //System.out.println("hello");
           
            b = units*rate;
           
        }
         public void get()
        {
        System.out.println("the value is"+b);
        }
    //public static void main(String[] args) {

        {
            domestic_plan d;
            d = new domestic_plan();
            d.getrate();
            d.calculate_bill(unit);
            d.get();
           
        }
        else if((plantype.equals("cp")))
        {
            commercial_plan c;
            c = new commercial_plan();
            c.getrate();
            c.calculate_bill(unit);
            c.get();

Write a java program to create an abstract class named Shape that contains two integers and an abstract method named printArea(). Provide three classes named Rectangle, Triangle and Circle such that each one of the classes extends the class Shape. Each one of the classes contain only the method printArea( ) that prints the area of the given shape.

package javaapplication3; abstract class shape { int a=3,b=4; abstract public void print_area(); } class rectangle extends shape { public int area_rect;         @Override public void print_area() { area_rect=a*b;                 System.out.println("The area of rectangle is:"+area_rect); } } class triangle extends shape { int area_tri;         @Override public void print_area() { area_tri=(int) (0.5*a*b);                 System.out.println("The area of triangle is:"+area_tri); } } class circle extends shape { int area_circle;         @Override public void print_area() { area_circle=(int) (3.14*a*a);                 System.out.println("The area of circle is:"+area_circle); } } public class JavaApplication3 {     /**     ...

Create Employee Class with Method getdata and setdata. Create following subclasses to generate biodata. i) Personal record ii)) Professional record iii) Academic record Assume appropriate data members and member function to accept required data & print bio-data. Use Overriding at suitable places.Create bio-data using multilevel inheritances.

Exception_Handling Program

Create an exception class named NegativeNumberException extended from the class Exception. This class should contain a parameterless constructor to call the Exception class constructor with the message “You should enter a positive number”. Create a class named exercise3 that contains: a) A method named M1 that accepts a double variable as argument and returns its square root. The method should throw the NegativeNumberException exception defined above. b) The main method to prompt the user to enter a number and then to call the method M1 (insert a try-catch block to handle the NegativeNumberException exception). package javaapplication5; import java.util.*; class NegativeNumberException extends Exception { public NegativeNumberException() { super("You should enter a Positive Number."); } } public class JavaApplication5 { public static void main (String[] args) {         Scanner s;               ...
