Question 1. Collect two integer values from the user. Based on these values display the sum, difference, product, average, distance (absolute difference), maximum and minimum. Sample output is provided below:
C:\Users\aaron\Desktop>java
Enter two integers:
10
20
Sum:30
Difference:-10
Product:200
Average:15.0
Distance:10
Maximum:20
Minimum:10
C:\Users\aaron\Desktop>java
Enter two integers:
101 52
Sum:153
Difference:49
Product:5252
Average:76.5
Distance:49
Maximum:101
Minimum:52
Do the same work outlined above BUT have the output aligned in the following manner:
C:\Users\aaron\Desktop>java
Enter two integers:
101 52
Sum: 153
Difference: 49
Product: 5252
Average: 76.5
Distance: 49
Maximum: 101
Minimum: 52
Question 2. Write a program that prompts the user to enter three number grades. The program then computes the average of the three grades and displays the letter grade for the three original grades and for the average. Letter grades are computed as follows:
• A+: 90-100
• A: 80-89
• B: 70-79
• C: 60-69
• D: 50-59
• F: < 50
See the sample output below for clarification.
C:\Users\aaron\Desktop>java question2
Please enter three number grades...
First grade: 80
Second grade: 76
Third grade: 68
First Grade: A
Second Grade: B
Third Grade: C
Average: B
Question 3. Write a Java application that is designed to help you determine the winner of a video game contest. The program takes in the names and points-scored of three competitors. Then it prints out who came in first (highest score), who is second and who is third (lowest score). If any of the scores are < 0, stop the program with an error immediately. See my example output below:
C:\Users\aaron\Desktop>java question3
Please enter the three competitor's names, separated by a new line:
John
Sally
Mark
Please enter John's score: 10000
Please enter Sally's score: 12000
Please enter Mark's score: 9750
First place: Sally!
Second place: John!
Third place: Mark!
Amend your program so that if there is a tie, that is taken into account. For example, if the top two players are tied, they are both awarded first place and the remaining player gets third. If the last two players are tied they both get second. If all three players are tied they all get first, and so on.
Note: Do not use Arrays, ArrayLists, or sorting algoritms to solve this question.
Question 4. Consider a cell phone provider with three data plans.
Plan A: $30 per month, 250 MB included. $10 per 250 MB above that.
Plan B: $40 per month, 1 GB included. $10 per 500 MB above that.
Plan C: $65 per month, 6 GB included. $10 per 1 GB above that.
Prompt the user to enter their plan letter and then the total number of GBs of data they used that month. If the total data used was less than 0 GB, quite the program immediately. Otherwise, compute and display their total charges.
C:\Users\aaron\Desktop>java
Please enter the letter corresponding to your plan: B
Please enter the amount of data you used (in GB): 2.5
Your total charges are $70
Arguably, for high data users, Plan A is the worst! If the user selected Plan A, show them how much they could have saved if they were using Plan B and C. If they selected Plan B, show them how much they could have saved using Plan C. Note: If NO savings could have been realized, do not show them the alternate plans.
Question 5. Write a java application that determines whether a user-entered integer is odd or even and whether it is evenly divisible by 3, 4, both 3 and 4 or neither 3 nor 4 (see my output below for clarification).
Assume the user will enter a positive integer. The output from my solution is shown below. Do your best to duplicate my output. Below is my output from running the program 5 times. Use boolean operators (&& or ||) in your solution.
C:\Users\aaron\Desktop>java
Enter an integer:12
12 is even.
12 is divisible by 3 and 4.
C:\Users\aaron\Desktop>java
Enter an integer:9
9 is odd.
9 is divisible by 3.
C:\Users\aaron\Desktop>java
Enter an integer:16
16 is even.
16 is divisible by 4.
C:\Users\aaron\Desktop>java
Enter an integer:13
13 is odd.
13 is neither divisible by 3 nor 4.
C:\Users\aaron\Desktop>java
Enter an integer:132
132 is even.
132 is divisible by 3 and 4.
Question 6. Write a program that collects three Strings from the user. Display the three strings in alphabetical order regardless of the order in which they were input.
Use boolean operators && and/or || in your solution.
(Hint: If you are having a hard time getting this to work with Strings try it with integers first. The logic is the same but the syntax is a bit different.)
C:\Users\aaron\Desktop>java
Please enter three Strings-
John Sally Victor
John
Sally
Victor
C:\Users\aaron\Desktop>java
Please enter three Strings:
John Victor Sally
John
Sally
Victor
