Assignment 6 –
How to submit: upload solution file to Blackboard
This assignment focuses on Java’s Lambdas and Streams discussed in Chapter 17 and generic classes discussed in Chapter 20. You will need to implement the four methods declared in the provided Java file.
For this assignment, you must use Java’s streams with intermediate and terminal operations (e.g.
𝑓𝑖𝑙𝑡𝑒𝑟, 𝑚𝑎𝑝, 𝑙𝑖𝑚𝑖𝑡, 𝑠𝑢𝑚 …). You are not allowed to use any looping structures (i.e. For, While, and Do‐While). For file input, you must use the 𝑗𝑎𝑣𝑎. 𝑛𝑖𝑜 package and not the 𝑗𝑎𝑣𝑎. 𝑖𝑜 package. However, you may use any of the exception classes from 𝑗𝑎𝑣𝑎. 𝑖𝑜 since there aren’t any in 𝑗𝑎𝑣𝑎. 𝑖𝑜!
Consult each method’s Javadoc for a description of that method’s task.
Note:
ü This is an individual assignment; please do your own work, sharing and/or copying code and/or solution ideas with/from others will result in a grade of 0 and disciplinary actions for all involved parties. If you run into problems and have done your best to solve them, please contact me before/after class or by e-mail.
ü A 20% grade deduction for every day the assignment is late.
