MODULE CLASS

METHODS | ERROR | SOLUTION | Module | Sem2Credits = sem1; | Sem2Credits = sem2; | getTotalCredits() | return sem2Credits+ sem3Credits; | Return sem1Credits + sem2Credits+ sem3Credits; |

* The Sem2Credits should be equals to sem2 because sem1 is equals to Sem1Credits. * The return in getTotalCredits() should have sem1Credits in it because the total credits requires adding the student’s results from semester 1 to semester 3.

This is testing the corrected Module Class. This shows that everything is correct now.

In checkModuleSelection() method, the System.out.println ("The value of sem1Credits is: " + sem1Credits); shouldn’t be inside the for loop. Also, the System.out.println should have another 2 for semester 2 and semester 3 credits.

In check getQualification() method, the return method for Merit and Distinction was the other way around.

This is the result of the correct code.

Testing

When I was testing the code. I had to debug it to make it that they all work properly.

I had to set up the breakpoint before I start debugging. This can be done by double left clicking the left side of the code which is shown in the picture.

I’m using this information which I typed in the Test.java to find out if the methods are working properly. By running the debug, I will keep clicking the Step Into button in order to process each line of the code to see if they are all correct. At the end of debugging this should come up which shows what happened to the code and I will get an output to see if the code is correct or not.

This shows that my code was wrong as I was supposed to get an output of 25. I will correct it by looking at the method that I debug and fix the code. This is how I debug for all the codes for this project and I believe that it went very well because I tried to test each method by using the correct and wrong inputs just to make sure that I will not get the wrong output of the code. I also used a lot of System.out.println for each methods to give me a chance to find out if I get the expected output which was very effective for this project. I believe that my testing and debugging strategies were very good as I was able to spot all the codes that were incorrect. By using the Step Into for debugging, it helped me find out which line of codes went wrong as it allows me to give me an output for each line of code that gets processed.
