Class CommandReader

java.lang.Object
  stockportfolio.CommandReader

All Implemented Interfaces:

java.lang.Runnable

public class CommandReader

extends java.lang.Object

implements java.lang.Runnable

Simple text-based shell for stock portfolio manager. Class CommandReader is a text-based UI for the stock portfolio project. It implements a very simple shell with four commands:

BUY stockname quantity price date
SELL stockname quantity price date
REPORT
EXIT

All commands are case insensitive, but the stockname case sensitivity depends on the underlying portfolio implementation. quantity and price are doubles and date should be in mm/dd/yyyy format. Any unrecognized entry will print a usage string, so HELP and ? will both provide help (as will ASDFASDFASDF.) There are only three methods, setIn, setOut and run. This should be enough to provide simple console-based or file- based exercising of the portfolio functions. The main method simply hooks in to System.in, out to System.out and calls run.
