    Question How to align text? Printf?

    Ok,

    I have a CS assignment due tomorrow and I am missing one of the requirements for the project.
    I have to write a program that asks a student for a list of information and then generates a report.
    It should display something like this:
    image.jpg

    So, I finished writing the code. But, I was not able to align the text properly.

    Here's a part of my code that I want to align (the whole thing is huge):

    System.out.print (subj1 + "\t"); //Subject 1
     
    System.out.printf ("%03d",gradesubj1); // Mark for Subject 1
     
    System.out.println (subj2 + "\t" + gradesubj2 + "%"); // Subject and Mark for Subject 2
     
    System.out.println (subj3 + "\t" + gradesubj3 + "%"); // Subject and Mark for Subject 3
     
     System.out.println (subj4 + "\t" + gradesubj4 + "%"); // Subject and Mark for Subject 4   
     
    System.out.println ("\nAverage : " + gradeavg + "%"); // Grades Average         
     
    System.out.println ("\nTotal money earned : $" + workmoneytotal); 
     
    System.out.println ("Number of affordable tutoring hours: " + tutoringhours_int + " hours");

    As you can see, I tried to align with System.out.printf ("%03d"....);
    The program compiles correctly. But when I run it, I get this:

    (part of the output)

    java.util.IllegalFormatConversionException: d != java.lang.Double
    	at java.util.Formatter$FormatSpecifier.failConversion(Unknown Source)
    	at java.util.Formatter$FormatSpecifier.printInteger(Unknown Source)
    	at java.util.Formatter$FormatSpecifier.print(Unknown Source)
    	at java.util.Formatter.format(Unknown Source)
    	at java.io.PrintStream.format(Unknown Source)
    	at java.io.PrintStream.printf(Unknown Source)

    	at java.lang.reflect.Method.invoke(Unknown Source)
    	at edu.rice.cs.drjava.model.compiler.JavacCompiler.runCommand(JavacCompiler.java:271)

    What's wrong?

    Thanks in advance

    IllegalFormatConversionException: d != java.lang.Double
    Look up the definitions for the formatting control letters.
    The program is telling you that d is not for doubles.
