Bank Line Implementation in Java using Multi threading - ITEC 3150, Spring, 2016

By Hassnain Jamil -
Implement a bank line of credit account.  The account will have two primary attributes, the credit limit and current credit balance.  The line of credit class should also contain a lock and a sufficient credit limit condition.  When initialized the current credit balance will be zero.  The credit limit should be determined at construction time.  The owner of the credit line can get money up to the credit limit and make payments until the balance is zero.   If a request is made for money than is available, the credit limit will return up to the limit, but not beyond it.  So the getMoney method should have a return value of how much money is returned.

 The credit line program should have two threads:  one to get more money from credit line and a second to make payments.  The thread to get more money increases the credit balance up to, but not beyond the credit limit.  The make payment thread decreases the current credit balance. 

The make payment thread should make random payments between $0 and $500 every 2 seconds for a total of 50 payments.  It should print payment made and new credit balance. The credit balance should not go below $0 so if an unneeded attempt at payment is made, it will not be accepted.

The get money thread should attempt to get more money of random amounts between $1 and $500 every 3 seconds for a total of 50 attempts to get money.  It should print requested amount and amount received.

Create a tester program to run the two threads.  The LineOfCredit class should have appropriate protections on increments and decrements of the credit balance.

[SOLVED] Tape for a Turing Machine using Doubly-linked List in Java with full source code

By Anonymous -
Tape for a Turing Machine (Doubly-linked List) Short exercise in which you will code part of an existing project. In this case, you will be working with a doubly-linked list. To make this topic more interesting, the list that you work on will be part of a Turing Machine. A Turing Machine is a kind of very simple, abstract computing device that was introduced in the 1930's by Alan Turing as a way of studying computation and its limitations. The classes that you need for the lab are in a package named turing. You will define a new class named Tape in this package. You can find the Java source in the code directory. You should copy this directory into an Eclipse project. There will be errors, since the existing classes depend on the Tape class, which you have not yet written. Don't forget the Javadoc comments. A Class for Turing Machine Tapes A Turing machine works on a "tape" that is used for both input and output. The tape is made up of little squares called cell

[SOLVED] Branch Coverage, Statement Coverage and Path Coverage | Java Unit Testing

By Anonymous -
Create a directory called “TestClassValue” Hereafter, we call this directory <dir>. Create a Java class com.work.sample.FlawedClass in directory <dir>/src. (The actual path will obviously reflect the package structure.) 100% Branch Coverage & 100% Statement Coverage Add to the class a method called flawedMethodl that contains a division by zero fault such that it is possible to create a test suite that achieves 100% branch coverage and does not reveal the fault every test suite that achieves 100% statement coverage reveals the fault. Conversely, if you were able to create the method, then create two JUnit test classes com.work.sample.FlawedClassTestBCl and com.work.sample.FlawedClassTestSCl for class FlawedClass as follows: FlawedClassTestBCl should achieve 100% branch coverage of flawedMethodl and not reveal the fault therein. FlawedClassTestSCl should achieve 100% statement coverage of flawedMethodl and reveal the fault therein. Both classes should be
