Help Java

Im using JCreator. and im getting an error when i compile this.

public static char computeLetterGrade(float percentGrade) {
if (percentGrade < 50) {
return 'F';
else if ((percentGrade >= 50) && (percentGrade < 60))
return 'D';
else if ((percentGrade >= 60) && (percentGrade < 70))
return 'C';
else if ((percentGrade >= 70) && (percentGrade < 80))
return 'B';
else
return 'A';
}
}

The error is:

'class' or 'interface' expected
public static char computeLetterGrade(float percentGrade) {
^

What should be changed?

What you have there is just a method. You either need to convert it to a class or write a class around it. Any file Blah.java must contain a public class Blah.
