Desperate HELP with Random Numbes in an Array & Do / While

Question

Please somebody help, I have been working this problem for over 7 days now and can't get it. I have tried everything from a while to a do while to this and that. I need to have an Array of 8 that when run will produce random numbers for output between 15 to 25. I CAN"T GET IT PLEASE HELP. I am new to JAVA and have done everything I can think of to resolve this. I even have purchased a new book and looked at every site trying to find a solution. PLEASE HELP! Here it is:
import javax.swing.*;
public class RandomArray{
public static void main (String [ ] args) {
JTextArea outputArea = new JTextArea ( );
int myArray [ ]; //array declaration
myArray = new int [ 8 ]; //allocating memory
String output = "Array values at initializatioon ";
output += "\nIndex\tValues";
for ( int i = 0; i < myArray.length; i ++)
output += "\n" + i + "\t" + myArray [ i ];
output += "\n\nArray values after assigning values within the range of 15 and 25";
do {( int i = 0; i <myArray.length; i++)
     while     myArray [ i ] = 15 + (int) (Math.random ( ) * 25);
output += "\n" + i + "\t" + myArray [ i ];}
outputArea.setText (output);
JOptionPane.showMessageDialog (null, outputArea,
"Array Value before and after",
JOptionPane.INFORMATION_MESSAGE);
     System.exit ( 0 );
The output that I need is in two columns one with the initial array 0-7 and the second should be random numbers 15-25. Please help, please

here you are :
import javax.swing.*;
public class RandomArray
public static void main (String [ ] args)
     JTextArea outputArea = new JTextArea();
     int       myArray [] = new int[8];
     String output = "Array values at initializatioon ";
     output += "\nIndex\tValues";
     for (int i = 0; i < myArray.length; i ++)
          output += "\n" + i + "\t" + myArray [ i ];
     output += "\n\nArray values after assigning values within the range of 15 and 25";
     for (int i = 0; i < myArray.length; i++)
          myArray [ i ] = 15 + (int) (Math.random ( ) * 10);
          output += "\n" + i + "\t" + myArray [ i ];
     outputArea.setText(output);
     JOptionPane.showMessageDialog (null, outputArea,
          "Array Value before and after",
          JOptionPane.INFORMATION_MESSAGE);
     System.exit(0);
