Lab Objectives
This lab was designed to reinforce the following programming concepts:
Using repetition structures.
Using decision making
Using /0 files.
Exercise#1: Counting Number of Digits
Write a Java program that inputs one integer number from the user, determine the number af individual digits and prin
the number of digits and the digits separated from one another by a tab space. For example, if the user types in the numbe
42339, the program should print "There are 5 digits, which are 4 2339",
Sample Input/Output
Enter an integer value: 12345678
There are(8 aigite, wrich are(1)2 3 45676
num/13
Exercise#2: Sales
A mal-order house sells five products whose retail arices are as follows: Procuct 1. $2. sa; product 2, 54.50;
product 3, 34. 481 Eroduct 4. $4.99 and product 5. $6.87. Write a Java program that reads a series of pairs
as foliows: product number and product name. The quantity sold is generated at randam between O and 50. Your program
should n a svitch statem.ent to deternine the retail price for each product. It should calculate and display the total retall
vair ol af praducts sold as shown in the sample auraut. The loop should stop laoping when there is no inout. The input is
stared in an inout file.
