A Java method enabling performance analysis of code: currentTimeMillis()

import java.io.*;
...
//currentTimeMillis() returns the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC
long startTime = System.currentTimeMillis();
...
long stopTime = System.currentTimeMillis();
long elapsedTime = stopTime-startTime;


Please begin and familiarize yourself with the following steps:

  1. Download (Right click/Save As...) the java files PointCP.java and PointCPTest.java to a specific directory you wish to work from (e.g. LAB1\).

  2. Start up Eclipse using the windows start button. Find the Eclipse application in the list of programs.

  3. Go to File, New -> Project.

  4. Select Java Project and click Next.

  5. Call your project 'lab1' and 'Create project from existing' browsing to the working directory your created in step 1. Click next.

  6. In the next window, you are able to modify the output folder as shown below and click Finish.
    (You don't have to, but I like to separate source and compiled code, so I set the output folder to be 'lab1\bin')

  7. You should now be in your editing environment. If you expand the folders shown bellow within the 'Package Explorer' window, you should see your respective java files.

  8. To run the code, select the Run option from the menu bar, then the 'Run...' option under that.

  9. Next, click Java Application on the left panel, and click the 'New' button at the top left.

  10. The 'Run' window will appear. Fill in the information corresponding to your main class (i.e. the class to run).

  11. The program will run in a little window (i.e. console) at the bottom of the screen as part of the IDE. If you want to run the program again, you can click the toolbar button showing a play button. Your run configuration will be displayed as an option.

  12. Proceed to the lab1 instructions
