Formatting toString method

I have a toString() method from my class that takes the information from the object and puts it into a string to be printed.

This is what it should look like:

Susan         70     <Average   C
Alexander     80     >Average   B

, but I'm having trouble formatting my toString() method. This is what it looks like this right now which is very unorganized.

public String toString() {

    return ("\n" + fullName + 
            "            " + relativeScore +
            "            " + testScore);

}

I would normally use printf, but since it's a return statement I can't use it. Any help would be much appreciated.

you're doing it wrong way. Susan is 5 letter word and Alexander is 9 letter word. So if susan is followed by 10 white spaces then alexander should be followed by 10-9+5= 6 white spaces. You should consider the length of fullname in your code.

Depending on what you want to achieve, you could simply use String#format, for example:

System.out.println(String.format("%-10s %d %10s %5s", "Susan", 70, "<Average", "C"));

Which outputs

Susan      70   <Average     C

String.format method returns a new String object, so you can use it rather than printf, for instance:

public String toString() {
    return String.format("%s\t%3d\t%s", fullName, relativeScore, testScore);
}

You could use String.format() and do it just like you would do with printf()

return String.format("whatever comes here");
