Java - function

Java - Assignment 04 (100 pts)

Instructions

• Write each exercise in its own method. Uncomment the function calls in main() to activate each

exercise. Refer to "Assignment01" if necessary.

• For each exercise, use comments to write pseudocode with at least one additional refinement

step. Include the pseudocode at the beginning of each method.

• Submit only one file containing all of your code. Multiple files not allowed!
• The knowledge required for this assignment is in the textbook / slides and your notes. You are

not allowed to use any additional resources, websites, external help... Doing so will be

considered plagiarism and / or cheating! If you need help, talk to a CIS tutor or to the professor.

• But you are allowed to assist your friends during the lab session in the presence of the professor.
• If you are having problems unrelated to the assignment (for example, you are unable to find a

specific function in your IDE, …), you can go ahead and check it on the Internet.

• Do not use functions/techniques that have not been covered in class yet. Doing so might be

mistaken for plagiarism and/or defeats the purpose of the exercise and will be graded 0.

• You are required to perform at least one submission at the end of the lab session, even if it’s

incomplete. You can complete it later and resubmit it; the latest one will be graded.

• Test all your methods at least 3 times in main() by calling them with different parameters

Exercise 01 (25 pts)

Write a method public static void distinct(int[] arrNumbers) that receives an array

of ten numbers and displays the number of distinct numbers and the distinct numbers separated by exactly

one space (i.e., if a number appears multiple times, it is displayed only once). (Hint: Read a number from

the input array and store it in a local array if it is new. If the number is already in the local array, ignore

it.) At the end, the local array will contain the distinct numbers. Here is a sample run of the program:

(assuming that the input array contains 1 2 3 2 1 6 3 4 5 2)

The number of distinct number is 6

The distinct numbers are: 1 2 3 6 4 5

Exercise 02 (30 points)

Use the following formula to compute the standard deviation of n numbers:
