Thread: 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

Grot

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
		 }	
 
 
	}
 
}

how to sort it in lexicographical order

Where are the numbers stored so you can sort them?

What does the program output when it executes?

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