compare the cpu efficiency among 3 data structures used in merging 2 data files

Objective: Compare the CPU efficiency among 3 data structures used in merging 2 data files.

Input data files: finalData.csv and finalNew.csv

The number of records in the input files is unknown.

Every input line consists of 4 fields, separated by commas:

date, email, phone number, password

Listed below are 2 sample lines:

12/02/2014,de@rigado.mt,(481) 228-1228,Y$L0g9knad@

12/10/1922,maw@bisfic.bo,(444) 384-1163,Jz*B7@HSN)Zq2VPy)Hmy


Please develop a Java program to show the CPU time needed to merge two input data files:

1. Display the CPU time used to read finalData.csv and finalNew.csv into java.util.HashMap

2. Display the CPU time used to read finalData.csv and finalNew.csv into java.util.SortedMap

3. Display the CPU time used to read finalData.csv and finalNew.csv into java.util.TreeMap

Hint: This program generates 3 lines of output.
