Number Sorting Program?

[ComicStix]

Hey! I'm working on this program that generates 100 random numbers and stores them in an array. This is the unsorted array. Then I use those same random numbers and try to make a sorted array. And it's supposed to be is ascending order like 2,4,6. Only 5 numbers per line though. I had a program earlier that worked but it used less numbers so I copy and pasted it here and it doesn't work. Only the bottom few numbers seem to be put in order. Anyone have an idea what I'm doing wrong? Code :

/**
 * Write a description of class Nicoleselsort here.
 * 
 * @author Nicole Daniels 
 * @version 1.0
 */
public class Nicoleselsort
{
     public static void main (String [] args) {
     int [] sel = new int [100];
     System.out.print("Unsorted");
     for (int i = 0; i < sel.length; i++){
       for (int l = 0; l < 100; l++)
       {
            //generates a random number
            double r = Math.random();
            double numb = (r * 100);
            int random = ((int)(numb));
            //sets the element at i to a random number
            sel[i] = random;
       }
     }
     for ( int i = 0; i < sel.length; i++)
     {
        if( i % 5 == 0)
        System.out.println("");
        System.out.print ( sel[i] + "\t");
     }
      System.out.println("");
      System.out.print("Sorted");
     for (int n = sel.length; n > 1; n--){
           //set n to the length of the array for comparison later on
         int max = 0;
         int temp = 0;
          for (int i = 0; i < n; i++){
            if (sel[i] > max)
            //scans the array and sets the largest number to max
             max = i;
         }
         //keeps scanning the array by decrementing array length by one and sets max
         temp = sel[max];
         sel[max] = sel[n-1];
         sel [n-1] = temp;
         if(n % 5 == 0)
         System.out.println("");
         System.out.print(temp + "\t");
      }
}
}

Output:

sure I don't understaodd exactly what are you tried to archieve, sorry my magic ball is tired, only continue by reads comment

System.out.print("Sorted");

if I add

Arrays.sort(sel);

then outPut ...

import java.util.Arrays;

public class NicoleSelSort {

    public static void main(String[] args) {
        int[] sel = new int[100];
        System.out.print("Unsorted");
        for (int i = 0; i < sel.length; i++) {
            for (int l = 0; l < 100; l++) {
                double r = Math.random();//generates a random number
                double numb = (r * 100);
                int random = ((int) (numb));
                sel[i] = random;//sets the element at i to a random number
            }
        }
        for (int i = 0; i < sel.length; i++) {
            if (i % 5 == 0) {
                System.out.println("");
            }
            System.out.print(sel[i] + "\t");
        }
        System.out.println("");
        Arrays.sort(sel);
        System.out.print("Sorted");
        for (int n = sel.length; n > 1; n--) {
            int max = 0;//set n to the length of the array for comparison later on
            int temp = 0;
            for (int i = 0; i < n; i++) {
                if (sel[i] > max) { //scans the array and sets the largest number to max
                    max = i;
                }
            }
            temp = sel[max]; //keeps scanning the array by decrementing array length by one and sets max
            sel[max] = sel[n - 1];
            sel[n - 1] = temp;
            if (n % 5 == 0) {
                System.out.println("");
            }
            System.out.print(temp + "\t");
        }
    }

    private NicoleSelSort() {
    }
}

if (sel[i] > max)
                          max = i;

This may be your trouble. Is max meant to be a value, or an index?

Ok thanks everyone! But I found the Arrays.sort method in the API and it helped me. But thanks for the help
