Exercise 1: New Sales Tax in Metro Atlanta Area (10pt) Starting from April 1, 2018, the sales tax rates in the metro Atlanta area have been increased to the following: County Inside City of Atlanta? Sales Tax Rate Yes 8.9% Fulton No 7.75% Yes 8.9% Dekalb No 8.0% Cobb N/A 6.0% C. Command Prompt C:\test>javac Hw3_Ex1.java C:\test>java Hw3_Ex1 County (1. Fulton; 2. Dekalb; 3. Cobb): 1 Inside City of Atlanta? (1. Yes; 2. No): 1 The sales tax rate is: 8.9% C:\test>java Hw3_Ex1 County (1. Fulton; 2. Dekalb; 3. Cobb): 2 Inside City of Atlanta? (1. Yes; 2. No: 2 The sales tax rate is: 8.0% C:\test>java Hw3_Ex1 County (1. Fulton; 2. Dekalb; 3. Cobb>: 3 The sales tax rate is: 6.0% C:\test> Exercise 2: Input Validation: Exercise 1 Revisited (10pt) In all exercises up until now, we simply assume all user inputs follow the supposed format and will always be valid. In real software applications, we need to account for possible invalid user inputs and make sure our programs are robust enough. In this exercise, let us revisit Exercise 1 (Sales Tax Rate) and add input validation to the program you just wrote. Save the improved program in a separate file as Hw3_Ex2.java. Your program needs to do the following input validations: (i) If the user's entry for the county is NOT an integer, display an error message and terminate the program immediately; (ii) If the user's entry for the county is an integer, but not between 1 and 3, then display an error message and terminate the program immediately; (iii) If the user's entry for whether inside Atlanta is NOT an integer, display an error message and terminate the program immediately; (iv) If the user's entry for whether inside Atlanta is an integer, but not 1 or 2, then display an error message and terminate the program immediately; C:\.
