Question

Write and document a set of Java classes implementing the time-series storage and analysis system described in Assignment 1. The data files from which time-series are derived are textfiles in which the first row specifies the number of rows and columns and the remaining rows specify a matrix in which all rows (columns) are of the same length. On such data file data1.txt is as follows:

9 3

1 10 3

2 9 3

3 8 4

4 7 6

3 6 8

2 5 9

5 4 9

6 5 9

7 6 2

This and data files data2.txt and data3.txt can be used for testing. The data-dictionary will be modeled as a file in which each line consists of four hash-mark ("#") separated fields, namely a data-file name, one of "row" or column, a row or column number, and units in which that row or column's values are expressed. A data-dictionary need not have entries for all rows or columns in a data-file. One such example data-dictionary file ddict1.txt is as follows:

data1.txt # column # 2 # mm

data1.txt # column # 3 # m/s

data2.txt # row # 1 # kg

data2.txt # row # 2 # mm

data2.txt # row # 3 # m/s

data3.txt # column # 4 # rainfall (mm/year)

This and data-dictionary file ddict2.txt and On system startup, the data-dictionary to be used will be specified as a command-line argument. You may assume that specified files exist and are formatted correctly.

I don't know how to get it started, any hints?
