Sorting randomly genareted string in alphapetic order

Question

import java.util.*;
public class test {
    public static char[] chars;
    public static Random random;
    static {
        chars = new char[26];//taking caracters from asci table
        for (int i = 0; i < 26; i ++) {
            chars[i] = (char) (97 + i);           
        random = new Random ();
    public static void main (String[] args) { //printing random characters
            for (int i = 1; i <= 10; i++ ) {                                                                          
            System.out.println(randomString(20)); 
    private static String randomString (int length) { //generating random
        char[] array = new char[length];
        for (int i = 0; i < length; i ++) {
            array[i] = chars[random.nextInt (chars.length)];
    return new String (array);
    i have this code.i found that in the forums and modified it a bit.but i have still problems to sort randomly genareted strings in alphabetic order.i have a method to do it.but i couldn't implement it correctly.the way that i try to sort them is
void sort(String[] a) {
  for (int i=0; i<a.length-1; i++) {
     for (int j=i+1; j<a.length; j++) {
        if (a.compareTo(a[j]) > 0) {
String temp=a[j];
a[j]=a[i];
a[i]=temp;
thats a method i try to use but i couldn't put it in a correct place in the code and couldn't call him.always it gives error.pls help this unexprienced java user...

Hard to understand your problems, because you're too vague. At one point you mention you don't know where to put your method, at another you say you don't know how to call your method. If that is the case (which seems unlikely but oh well) here's an example.
public class Testing9 {
     public Testing9() { // constructor
          String basicString = "BasicExample";
          String sortedString = mySortMethod(basicString); // call mySortMethod passing the string
          System.out.println("sortedString = " + sortedString);
     public static void main(String[] args) { // main method starts app
          Testing9 app = new Testing9(); // calls constructor
     public String mySortMethod(String s) { // put the method here cause I feel like it
          String sortedString = "";
          // do your own work here to sort, etc....
          return sortedString;
}
