CSC 236 – Data Structures in Java – Lab 7

Lab 7 is due Monday., 5/9 by 11:59 pm.

Submit ONE PDF file with your source code and for the output only, it should be screenshots.

DO NOT COPY CODE FROM THE INTERNET!

Lab Standards:

You should adhere to the following rules in the programs that you submit:
 Avoid using global variables.
 Global constants are fine to use in programs.
 Put a comment with your name and the lab number at the top of every lab.
 Put a comment at the beginning of every method except simple constructors.
 Comment any complex section of code inside a method.
 When prompting a user in a loop, tell the user what to enter to exit the loop.
 Do not give an error message after the user enters a code that should exit from a loop.
Use priming read to avoid this.
 Use meaningful variable names. Names such as i, j, or k should only be used for loop
counters. Variable names like x and y should only be used for x and y in
mathematical programs.
 Do not write infinite loops with a break inside. Use the condition, which causes the
break as the loop condition. Infinite loops with breaks make your code very difficult
to read.

Lab Assignments:

 The labs are a critical part of the course. The only way to improve your ability to code
is to practice writing code. If you are having problems with the labs, you are strongly
encouraged to contact your instructor via e-mail. Most likely, you will find the labs in
data structures a bit more challenging than in your previous Java courses. This is
because we are not just learning about specific data structures, we are also working
on building our programming skills.
 Using the Internet to ask questions or “get ideas” is strongly discouraged. “Getting
ideas” online means you are not learning to program; you are dependent upon outside
help. Questions should be directed to your instructor. Copying code found online is
cheating; see the Honesty Policy section below.
 Make sure that you follow the requirements in the assignment. Do not change the
input values or format; do not change the output format.
 Labs will be submitted through Canvas as one PDF file. Labs are not accepted late
through e-mail.
 All labs should be written in TextPad, Eclipse, NetBeans, BlueJ, jGRASP (freeware),
Greenfoot, or run in an appropriate SDK. You may use any Java SDK. Moreover, you
may work in the Linux environment.
 If your lab “appears” copied or shared, then you will receive NO credit for the lab. A
second offense will result in an “F” for the course grade.

 You need the following comments at the top of each program:

//NAME

//CSC 236-IN

//For example, for lab 1, say, Lab 1-A or 1-B or 1-C, etc.
