I. Intro

1. project introduction

Project ProblemShooter is a java project that

1. reads problem bank files,
2. chooses random problems out of them,
3. and print it as a .txt file

notification : this project is not about troubleshooting; this program literally 'shoots problems' to the output file.

2. project motivation

This project was first suggested by corpral Cho. He wanted to study with sample exams, which was unavailable in the market. He already had the problem bank; the only problem was that he had to choose problems himself and make the exam sheet. It was both bothering and time-taking. That's when I heard this story. I thought it will be a great chance to revive my Java coding skills and keep it sharp. I was quite confident about it, for in my highschool years, I had developed one just like it. It was a program that erases given keywords from the passage to make a fill-blanks exam sheet.

3. keyword Definition

1) big index, small index

This is my own comprehension of naming category levels. For example, this part is in big index 1, small index 3. The bank Mr.Cho provided had only two levels.

2) (to) shoot problems

This term means this project is "exporting each problem content to the output channel.' By problem content, I mean (1) question, (2) answer, (3) and a list of wrong choices.

3) IterateIndex

In this project, each index chosen is driven by objects named IterateIndex. This object has bigIndex,smallIndex as attributes, and some methods for driving them.

II. Project Overview

process #1. get grasp of bank status

In the directory, a .txt file named chapters.txt has the number of small indexes for each big indexes.

process #2. choose random small indexes

process #3. load random problems of chosen indexes

process #4. export them
