BUILD OUTPUT DESCRIPTION

========================

When you build an Java application project that has a main class, the IDE automatically copies all of the JAR files on the projects classpath to your projects dist/lib folder. The IDE also adds each of the JAR files to the Class-Path element in the application JAR files manifest file (MANIFEST.MF).

To run the project from the command line, go to the dist folder and type the following:

java -jar "TraceMethod.jar"

OR

You can run it manully also from repo

To distribute this project, zip up the dist folder (including the lib folder) and distribute the ZIP file.

Notes:

• If two JAR files on the project classpath have the same name, only the first JAR file is copied to the lib folder.

• Only JAR files are copied to the lib folder. If the classpath contains other types of files or folders, these files (folders) are not copied.

• If a library on the projects classpath also has a Class-Path element specified in the manifest,the content of the Class-Path element has to be on the projects runtime path.

• To set a main class in a standard Java project, right-click the project node in the Projects window and choose Properties. Then click Run and enter the class name in the Main Class field. Alternatively, you can manually type the class name in the manifest Main-Class element.

Prerequisite:

1. The java program should be compiled.

2. https://adoptopenjdk.net/ -- OPENJDK

3. JFreeChart if you want to edit the code. For Bar-chart prepration

Steps

Step1: Open the TraceMethod.jar file by double click.

Step2: Choose the ".class" file you have to analyze or compare.

Step3: Click from the below two options if "Compare" clicked then go to Step 4 or else go to step 5.

Step4:

Step4.1: Run all 4 commands on cmd from anywhere and click  and click proceed.

Step4.2: The output is the two tables with 2 trace data.

Step5:

Step5.1: Run the 2 commands on cmd from anywhere and click  and click proceed.

Step5.2: The output is the two table trace data.

Step5.3: Click on Barchart to get the bar chart of the frequency of the methods.

NOTE : You can run the cmd command from anywhere.

The code is in TraceMethod.rar file named as TraceMethod-CODE.rar you have to extract it to see whole code and work in java.

Please delete a.trc, b.trc, a.log, b.log from your class file locations.
