method in class cannot be applied to given types

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

Answer 1

call generateNumbers(numbers);, your generateNumbers(); expects int[] as an argument ans you were passing none, thus the error

Answer 2

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.

Answer 3

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.

Answer 4

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 + " your GPA is " +
         gpa + " so your credit is $" + credits);
   
   }

   public static void main (String args[]) 
   {
      String studentName;
      double gradeAverage;
      Scanner inputDevice = new Scanner(System.in);
      System.out.println("Enter Student name: ");
      studentName = inputDevice.nextLine();
      System.out.println("Enter student GPA: ");
      gradeAverage = inputDevice.nextDouble();  
      
      computeDiscount(studentName, gradeAverage);
   }
}
