Problem1: Assume you own a grocery shop where clients always buy 3 items (all prices are in dollars). To facilitate the billing process you write a program that reads the item names and prices and generates an invoice. For example, if a client buys Chocolate (at $0.5), Gum (at $1), Water (at $0.5), the program output should look as follow: Please enter the first item name: Chocolate Please enter the first item price: 1.5 Please enter the second item name: Gum Please enter the second item price: 1.5 Please enter the third item name: Water Please enter the third item price: 1.5 Invoice is: Chocolate $1.5 Gum $1.5 Water $1.5 Total $4.5 Note that all prices are in dollars and you should use number formats to generate the invoice (do not use string concatenation to add the dollar sign).

Then the code will display the maximum grade, minimum grade, and average of the. Then compute the average letter grade using the conditional statement(if else) and print the class average. Please enter the grades: 85 98 72 64 53 Then, your program should print: Maximum: 98 Minimum: 53 Average: 74.4 The Class Average is: C+ Solution: http://www.javaproblems.com/2013/12/calculating-minimum- maximum-and-average.html Problem 3: Write a program that takes the name and the age of the user. The program should check the age of the user and then prints out if the person can get his driver license or not. If the age is under 18 then you should print “ ……. Too young to get his/her driving license” If the age is greater than or equal to 18 then the program should print “……. can have his/her Driving License”. The program should look as follows: Enter Name: Talal Enter Age: 16 Talal is too young to get his driving License Solution: http://www.javaproblems.com/2013/12/legal-age-calculator-in- java.html
