Nested Loops

Hello,
I am currently playing with loops and am stumped on something. I am inputting x amount of values assigned to a random number. For every 5 values, i want to increment a value +1;

Example (setting number to 7):
Value 0, -23, 1
Value 1, -25, 1
Value 2, 50, 1
Value 3, 13, 1
Value 4, 08, 1
Value 5, 10, 2
Value 6, -82, 2

Here's what I currently have:

import java.util.Scanner;  // Scanner
import java.util.Random;   // Random

    public class sup 
    {
        private static Scanner scanner = new Scanner( System.in );
    
        public static void main ( String[] args )
        {
            
            System.out.print( "Input number of values in the array: " );
            String input = scanner.nextLine();
            int number = Integer.parseInt( input );
            
            int array[] = new int[number];
            
            Random generator = new Random( 3 );
            
            for(int x = 0; x < number; x = x + 1)
            {
               for(int y = x; y < 5; y=y+1) //I know I'm doing something wrong here
               {
            	   if(y ==4)
            	   {
            		   System.out.println(y);
            	   }
               }

            	
            	
               int r = generator.nextInt();
        	   array[x] = r; 

        	   System.out.println( "Index: " + x + " Value: " + r );
            
            }
           
        }
        
    }

move to Java category if possible mods
