Bubble Sort with random numbers

Hi I am pretty new to java and one of my assignments in university is causing me a problem and I just can't seem to figure out where i'm going wrong.

My specification is:

1] Creating a real random number between "0" and "20" using the "Random" constructor with a seed of 123456
then
2] Creating an array of 30000 different random numbers using this seed
then
3] Using a bubble sort (without using the "java.util.Arrays.sort" or "java.util.Collections.sort" methods) to identify the highest 10 elements of that array.
then
4] Printing out those 10 figures to screen.

The code I have made so far is:

Code :

---

import java.util.Random;
 
 
public class BubbleSort{
  public static void main(String a[]){
	  Random rndNumbers = new Random();
      int rndNumber = 0;
 
      for (int nbr = 0; nbr < 10; nbr++) {
          rndNumber = rndNumbers.nextInt(3000);
          System.out.println("Number: " + rndNumber);
          int[] x = new int[6];
          for (int i=0; i<x.length; i++);
  int i;
  int array[] = {rndNumber};
  System.out.println("Values Before the sort:\n");
  for(i = 0; i < array.length; i++)
  System.out.print( array[i]+"  ");
  System.out.println();
  bubble_srt(array, array.length);
  System.out.print("Values after the sort:\n");
  for(i = 0; i <array.length; i++)
  System.out.print(array[i]+"  ");
  System.out.println();
  System.out.println("The bubble sort algorithm has put the random integers into order!");
  }
  }
 
  public static void bubble_srt( int a[], int n ){
  int i, j,t=0;
  for(i = 0; i < n; i++){
  for(j = 1; j < (n-i); j++){
  if(a[j-1] > a[j]){
  t = a[j-1];
  a[j-1]=a[j];
  a[j]=t;
  }
  }
  }
  }
}

For some reason it is only generating one random number at a time. Can anybody help me please?:-?
Any help would be great, thanks!

You should be held back a year in school there...

But so that does not happen....

Code java:

---

import java.util.Random;

Notice how I used just one array. Also you were seeding 3000 and creating random numbers from 1 to 123456. this has all been fixed.

Now I'm gonna get yelled at for spoonfeeding you. I don't care. I was bored.

Note: I've been doing java for only 14 days... I started programming in basic in 1986.
