Question

I m creating a program that generates 100 random integers between 0 and 9 and displays the count for each number  I m using an array of ten integers  counts  to store the number of 0s  1s       9s    When I compile the program I get the error       RandomNumbers java 9  error  method generateNumbers in class RandomNumbers cannot be applied to given types                  generateNumbers         required  int        found generateNumbers         reason  actual and formal argument lists differ in length   I get this error for the lines of code that I call the methods generateNumbers   and displayCounts   in the main method       public class RandomNumbers           public static void main String   args                   declares array for random numbers         int   numbers   new int  99              calls the generateNumbers method         generateNumbers               calls the displayCounts method                 displayCounts                                                                                         private static int generateNumbers int   numbers            for int i   0  i  lt  100  i                 int randomNumber              randomNumber    int  Math random    10               numbers i    randomNumber          return randomNumber                                                                                                  private static void displayCounts int   numbers           int   frequency   new int 10            for int i   0  size   numbers length  i  lt  size  i                  System out println  i      counts       frequency i                      end of displayCounts         end of class

The generateNumbers int   numbers  function definition has arguments  int   numbers that expects an array of integers  However  in the main  generateNumbers    doesn t have any arguments  To resolve it  simply add an array of numbers to the arguments while calling thegenerateNumbers   function in the main

I think you want something like this   The formatting is off  but it should give the essential information you want     import java util Scanner  public class BookstoreCredit        public static void computeDiscount String name  double gpa              double credits        credits   gpa   10        System out println name    quot  your GPA is  quot             gpa    quot  so your credit is   quot    credits                public static void main  String args                String studentName        double gradeAverage        Scanner inputDevice   new Scanner System in         System out println  quot Enter Student name   quot          studentName   inputDevice nextLine          System out println  quot Enter student GPA   quot          gradeAverage   inputDevice nextDouble                   computeDiscount studentName  gradeAverage

call         generateNumbers numbers    your         generateNumbers    expects int   as an argument ans you were passing none  thus the error

User · Answer

generateNumbers   expects a parameter and you aren t passing one in   generateNumbers   also returns after it has set the first random number - seems to be some confusion about what it is trying to do
