Question

I get this java.util.MissingFormatArgumentException error. I'm not sure how to round the value if print f doesn't work in this way.

SumofWeights2 = (Exam1Weight + Exam2Weight + FinalExamWeight + LabsWeight + ProjectsWeight + AttendanceWeight + QuizzesWeight);  
   SumofWeightxScore = (Exam1Weight*Exam1Score + Exam2Weight*Exam2Score + FinalExamScore*FinalExamWeight + LabAvg*LabsWeight + ProjectAvg*ProjectsWeight + QuizAvg*QuizzesWeight + AttendanceAvg*AttendanceWeight);
       CurrentScore = (SumofWeightxScore/SumofWeights2);
       x = (HundredxFinalOverallScore - SumofWeightxScore);
       y = (100 - SumofWeights2);
       AvgToFinalLetterGrade = (x/y);
       System.out.printf("Current Grade Score:%1.2f " + CurrentScore);
       System.out.println();

ERROR CODE BELOW:

Current Grade Score:Exception in thread "main" java.util.MissingFormatArgumentException: Format specifier '%1.2f'
   at java.util.Formatter.format(Unknown Source)
   at java.io.PrintStream.format(Unknown Source)

Explanation / Answer

Please correct this: "  System.out.printf("Current Grade Score:%1.2f " + CurrentScore); "

in to

" System.out.printf("Current Grade Score:%1.2f " , CurrentScore); "

Instead of '+' use ',' beacause if you are using printf you need to specify the placeholders as printf parameters.

That is instead of using string concatenation, specify the value to replace the placeholder.
