Retail Transaction Programming Project The skills you have

Retail Transaction Programming Project The skills you have developed in using tools such as Java, NetBeans, and UML and applying Java programming constructs such as selection, looping, classes, objects, and arrays will be crucial in the development of your first programming project. Programming Project 1 provides you with the opportunity to apply all of the concepts you have covered in the first 5 weeks to create a program that emulates a system for handling purchases and other transactions at a retail store.Carefully review the requirements in the attached Retail Transaction Programming Project document. You will then create a new project in NetBeans to implement Programming Project 1. Submit your completed Programming Project 1 by creating a zip archive of your Programming Project 1 NetBeans project folder and submitting the zip archive.Rubric:Program ClassesThe program includes the two classes LineItem and Transaction, each with the specified instance variables.LineItem class MethodsThe LineItem class includes all specified methods, including constructor and accessor methods, and each method performs the function described in the instructions.Transaction class MethodsThe Transaction class includes all specified methods, including constructor and accessor methods, and each method performs the function described in the instructions.toString MethodThe toString method of the Transaction class displays the transaction information as a single string, formatted precisely as described in the instructions.Form and StyleThe program adheres to Java programming conventions, including (but not limited to) proper indentation and spacing, appropriate commenting, and readable code.

Assignment 2

I need to make a custom memory appender for java using log4j.

Here is some specifications.

MemoryAppender stores all log entries in a list, they are not printed at theconsole
logs can be accessed using the following API:
java.util.List<org.apache.log4j.spi.LoggingEvent> MemoryAppender.getLogs()
c. the list returned by getLogs() should not be modifiable
MemoryAppender has a property maxSize , if the number of logs reaches
maxSize , the references to old logs are moved to a secondary list. getLogs()
returns the merged content of both list (primary and secondary). The use of the
secondary list should be transparent, i.e., it should not be visible to the outside,
and must not create memory leaks. I.e., if the amount of information logged
becomes so large that the JVM might run out of memory, log entries should be
culled automatically.
e. the constructor of MemoryAppender can be used to set the (primary) list to be
used to store logs
