Compiler error class interface or enum expected

Question

I have been troubleshooting this program for hours  trying several configurations  and have had no luck  It has been written in java  and has 33 errors  lowered from 50 before   Source Code     This program is named derivativeQuiz java  stored on a network drive I have permission to edit The actual code starts below this line  with the first import statement     import java util Random  import java Math    import javax swing JOptionPane  public static void derivativeQuiz String args             a bunch of code     The error log  compiled in JCreator    --------------------Configuration   lt

Process completed    I feel like this is a basic error  and yet I can t seem to find it  If it makes a difference  I am using JCreator to compile and everything is installed correctly   UPDATE  I have fixed the errors involved  Class declaration and incorrect import statements  someone went back and deleted a few semicolons    Working code   import java util Random  import javax swing JOptionPane  import java lang String  public class derivativeQuiz source  public static void main String args            a bunch more code       Thanks for all the help

Look at your function s definition  If you forget using      after function declaration somewhere  you ll get plenty of errors with the same format             class  interface  or enum expected       And also you have forgot closing bracket after your class or function definition ends  But note that these missing bracket  is not the only reason for this type of error

Every method should be within a class  Your method derivativeQuiz is outside a class   public class ClassName        your methods

class  interface  or enum expected  The above error is even possible when import statement is miss spelled  A proper statement is  import com company HelloWorld    If by mistake while code writing editing it is miss written like   t com company HelloWorld    compiler will show  class  interface  or enum expected

the main method should be declared in the your class like this    public class derivativeQuiz source         bunch of methods            public static void main String args                     code
