Assignment #4 Instructions
- 10.1 Exercise 3:
- Write a method called removeEvenLength that takes an ArrayList of strings as a parameter and removes all of the strings of even length from the list.
- Given the list ["1", "12", "123", "1234"] your method will modify the list leaving ["1", "123"].
- NOTE: this is not a method being added to your ArrayIntList class ... it is a static method that works on an ArrayList.
- Name your new class <your name>_Assign4a.java.
- Your program must EXACTLY match the designated output found in Assign4aOutput.txt.
- Use the provided Assign4aTester.java main program tester to verify your method is correct.
Add your removeEvenLength() method to this tester program.
- 11.2 Exercise 6:
- Write a method countUnique that accepts a list of integers as a parameter and returns the number of unique integer values in
the list. Use a set as auxiliary storage to help you solve this problem. For example, if a list contains the values [3, 7, 3, -1, 2, 3, 7, 2, 15, 15]
your method should return 5. The empty list contains 0 unique elements.
- NOTE: this is not a method being added to your ArrayIntList class ... it is a static method that works on an List.
- Name your new class <your name>_Assign4b.java.
- Your program must EXACTLY match the designated output found in Assign4bOutput.txt.
- Use the provided Assign4bTester.java main program tester to verify your method is correct.

Assignment Grading
The assignment is worth 35 points.
This is pretty simple...you get 100% if your output exactly matches the expected output...and...0% if it has ANY differences.
Make sure you get all the spelling, capitalization, punctuation, spacing, etc. correct! Hint: copy-n-paste is a wonderful thing! :)
