Generating random numbers between 999999 - 1000000 with an alpha number at the end

Hey every I'm stuck with trying to generate 1000 random numbers that have 7 digits my code is here below
I don't know how to set it to a fix digit number, I know it's simple but it's doing my head in
can anyone help me? thanks
I want numbers between 0000001 - 9999999 if possible with a character at the end
Ok the output is in a txt file

Random PPS Number : 1911462N
Random PPS Number : 2714102K
Random PPS Number : 5070317E
Random PPS Number : 8030837K
Random PPS Number : 4358369S
Random PPS Number : 5350002N

but my problem is I don't know how to sort it in lexicographical order

import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.Random;
 
 
public class Assignment_Part2{
 
	/**
	 * @param args
	 */
 
	 private static PrintWriter outputStream;
 
	 public static void main(String[] args) {
		 String fileName = "pps.txt";//input the data to a file named text.txt
		 try {//using the try catch operator 
		 	outputStream = new PrintWriter(fileName);// using the printwriter method to insert data to the file
		 	Random r = new Random();
		    String alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
		    for (int i = 0; i < 1; i++) {
 
		    } // prints  random characters from alphabet
		 	for (int j = 1; j <= 1000; j++){// using a for loop to gernerate numbers from 9999999 - 1000000
		 		int myInt = 1000000 + (int)(Math.random() * ((9999999 - 1000000) + 1));	
		 		outputStream.println("Random PPS Number : "   + myInt + alphabet.charAt(r.nextInt(alphabet.length())) + " ");//output stream to print the numbers to the pps.txt file
		 	    }  	 		
 
		 	// stores in Ram First
		 	outputStream.close(); // flushes the data to the file
 
		 	System.out.println("PPS Numbers Are Printed Out In A Text File");//outputs to the user that it's done
 
		 } catch (FileNotFoundException e) {// the catch operator is used to give the user an error 
 
		 	System.out.println("File Not Found");//outputs this if an error is found
		 }	
 
 
	}
 
}

Fixed numbers I mean from 1000000 - 9999999
I fixed it there.
my problem is how do I sort it in lexicographical order

Thanks

Where are the numbers stored so you can sort them?

What does the program output when it executes?

The numbers are stored in a txt file e.g
Random PPS Number : 1911462N
Random PPS Number : 2714102K
Random PPS Number : 5070317E
Random PPS Number : 8030837K
Random PPS Number : 4358369S

To sort them, they need to be in some kind of data structure in the program like an array or a collection.

Ok thanks Norm
