Java Programming using Linux Record programs

  1. Write a Java program to find the number of and sum of all integers greater than 100 and less than 200 that are divisible by 7

  2. Write a Java program to check whether a number is palindrome? Using Command Line arguments

  3. Write a Java program to perform Constructor Overloading

  4. Write a Java program to calculate the volume of different objects using method overloading

  5. Write a program to implement a class called Square with a method area(double a) that finds the area of the square. A class Cube which is a subclass of Square and an overriding method area(double a) that finds the surface area(6a^2) of a cube

  6. Write a program to implement a class with a method to find the area of a rectangle and a subclass to find the volume of a rectangular shaped box

  7. Program to implement an abstract class Perfect with abstract method void special(int n).A subclass of this class be Square and implement the special(int n) that finds the numbers that are perfect squares from 1 to n

  8. Write a Java program to implement dynamic method dispatch

  9. Create a class called Alpha with int x as instance variable, a constructor and a method alphaShow() to display x .Beta is a subclass of Alpha with with 2 intance variables float p and float q,a constructor and a method betaShow() to display p and q. (use superkeyword to invoke base class constructor)

  10. Program to implement an interface called Exam with a method pass(int mark) that returns a Boolean. Write another interface called Classify with a method Division(int average) which returns a string.Write a class called Result which implements both Exam and Classify.The pass() method should return true if the mark is greater than or equal to 50 else false.The Division() method must return “FIRST” when the parameter average is 60 or more, ”SECOND” when average is 50 or more but below 60, “NO DIVISION” when average is less than 50

  11. Create a class StringSort which contains a string array as data member.Include member functions to read an array of strings, to display the array and sort the array

  12. Write a complete java program to find whether the string “t” is contained in the given string.If so it returns the offset of first match. If not it returns -1

  13. Java program to print salary slip of n employees using user defined packages

    javac salarypack/Salary.java
javac Employee.java
java Employee

  14. Create a class Account with the data members account number, balance, name and any other required. Create a Menu driven application to perform the following

    i) Deposit
    ii) Withdraw
    iii) Display the details

    The program should work for n accounts

  15. Create a class Matrix which contains a two dimensional integer array m, n (order of matrix) as data members. Include the following member functions.

    i) to read the matrix
    ii) to display the matrix
    iii) to find the tranpose of the matix

  16. Program to create a package named shapes and define abstract class Shape inside it. The Shape class should have an abstract method getArea(). Define two subclasses Rectangle and Circle that extends the Shape class and implements the getArea() method. Create a class FindArea in a different package and use the Rectangle and Circle classes to find the areas of a reactangle and a circle

    javac shapes/Shape.java
javac shapes/Rectangle.java
javac shapes/Circle.java
javac finalpack/FindArea.java

java finalpack/FindArea
