Exercises

Exercise No.	Description	Filename
Exercise 2.10	Write an application that displays the number 1 to 4 on the same line, with each pair of adjacent numbers separated by one space.	Exercise0210.java
Exercise 2.11	Write an application that asks the user to enter two integers, obtains them from the user and prints their sum, product, difference and quotient (division).	Exercise0211.java
Exercise 2.12	Write an application that asks the user to enter two integers, obtains them from the user and displays the larger number followed by the words "is larger". If the numbers are equal, print the message "These numbers are equal".	Exercise0212.java
Exercise 2.13	Write an application that inputs three integers from the user and displays the sum, average, product, smallest and largest of the numbers.	Exercise0213.java
Exercise 2.19	Write an application that reads five integers, determines and prints the largest and smallest integers in the group.	Exercise0219.java
Exercise 2.20	Write an application that reads an integer and determines and prints whether it is odd or even.	Exercise0220.java
Exercise 2.21	Write an application that reads two integers, determines whether the first is a multiple of the second and prints the result.	Exercise0221.java
Exercise 2.22	Write an application that inputs from the user the radius of a circle as an integer and prints the circle's diameter, circumference and area using the floating-point value 3.14159 for π.	Exercise0222.java
Exercise 2.23	Write an application that inputs one number consisting of five digits from the user, separates the number into its individual digits and prints the digits separated from one another by three spaces each.	Exercise0223.java
Exercise 2.24	Using only the programming techniques you learned in this chapter, write an application that calculates the squares and cubes of the numbers from 0 to 10 and prints the resulting values in table format	Exercise0224.java
Exercise 2.25	Write a program that inputs five numbers and determines and prints the number of negative numbers input, the number of positive numbers input and the numbers of zeros input.	Exercise0225.java
