There are numerous opportunities for errors in any program, many times in places that seem too simple to require close attention.

Questions: Introduce the following errors, one at a time, in the program TempConverter.java. Write in your own words any error messages that the compiler produces. Fix the previous error each time before you introduce a new one. If no error messages are produced, try to run the code and explain what happens. If still no errors are produced, explain why.

a) Change TempConverter to tempConverter.

b) Remove the first quotation mark in the first string literal in the first System.out.println( ) statement.

c) Remove the semicolon at the end of the first println( ) statement.

d) Remove the last brace in the program.

e) Change the variable name fahrenheitTemp to fahrenheit in any one place in the code.

Part #2 - Arithmetic Expressions

Include the answers to these questions as comments above your code for Part 3 below.
1. Assume that you have a program that contains the following three lines of code. What is the value stored in the variable mystery after each line in the following code segment (You should have an answer like a) mystery has the value . . . b) mystery now has the value . . . )? Each line below assumes the previous ones have been executed.

a) int mystery = 5;

b) mystery = mystery - mystery / 2;

c) mystery = mystery + 1;

2. Assume that you have the following variables declared:
int a = 3, b = 10, c = 7;
double w = 12.9, y = 3.2;
What do the following expressions evaluate to in Java?

a) a / b

b) (double) b / a

c) a - b / c

d) w / (int) y

e) y / w

f) b % c / a

g) b % a

Part #3 - Programming
Write a Java program called Assignment1.java that will calculate the tip to leave at a restaurant. Your program must ask the user for the amount of the bill (this could contain decimals), and the percent they want to tip. The user will enter the percent they want to tip as an integer, e.g. 15 for 15%. Then your program should calculate and display the tip amount and the total bill after including the tip. To calculate the tip amount, multiply the bill amount times the percent divided by 100 (be careful of integer division). Make sure to use the following to get full credit:
• Comments explaining the main parts of the code (Getting input, calculating results, etc)
• Descriptive variable names with appropriate types
• Appropriate indentation between braces
• Use the NumberFormat class to format the output to be display as currency as demonstrated in the Coding Sample video.
For this and all subsequent assignments, provide a heading (in comments) described above and demonstrated in Part #1. Make sure your program is called Assignment1.java.

Sample Output
Below is sample output with input in bold. Your output does not need to match directly.

Sample 1
Enter the bill amount: $100.00
What percent would you like to tip: 15
Tip Amount: $15.00
Total amount with tip: $115.00

Sample 2
Enter the bill amount: $15.50
What percent would you like to tip: 10
Tip Amount: $1.55
Total amount with tip: $17.05
