For this Assignment, you will update an existing Java program using
 the NetBeans IDE. You will use the NetBeans Integrated Development 
Environment to make changes to an existing NetBeans Java Project. This 
existing program correctly sorts the data without using threads and 
contains a method (threadedSort) that you will update to sort the data 
using threads. To prepare: Read this week’s Resources. Download and 
Install NetBeans: Visit the NetBeans download page from this week’s 
Resources. Download the Java SE bundle. ( Note: Select the most recent 
release version, not a Beta version.) Run the downloaded package to 
install it. Choose the default options for installation. Unzip and open 
the Unthreaded Program: Download and unzip the file Week2_Project.zip. 
This will create a folder containing a NetBeans Project with the 
non-threaded java program. Note the location of this folder. Launch the 
NetBeans IDE. Click the Open Project... button (Or click the File 
drop-down menu and select Open Project… ). Navigate to the project 
folder, select it, and click Open Project . The Java Project contains 
three class files: MergeSort.java, Sort.java, and SortTest.java. 
Double-click each file in the Project section (at the left of the 
NetBeans IDE window) to display the file’s contents. Each of the Java 
class files contains comments explaining the purpose of the class and 
the purpose of the class’ methods. By Day 7 , modify the Java program by
 adding threads, and analyze the performance of both the threaded and 
non-threaded versions. Modify the Program: Improve the performance of 
the Java program by adding threads to the Sort.java file. Implement the 
threadedSort() method within the Sort class. Reuse any of the existing 
methods by calling them as necessary from your threadedSort method. You 
may add additional methods to the Sort class, if necessary. Analyze the 
Program: When running the provided SortTest program, the output presents
 data to support analyzing the performance of the threaded and 
non-threaded sort methods. Analyze your threaded implementation by 
comparing its performance to the original non-threaded implementation 
and explain the measured behavior. Document your analysis as a short 
paper (1–3 pages), using APA format. Be sure to discuss the relative 
performance improvement you expect for your threaded implementation and 
how the expected performance compares to the measured performance.
