}how do i save the random numbers?????

Answer 1

That was a quick sample. I'm guessing you're not too familiar with java. I expect the error was because you havn't imported the java.io library.
import java.io.*;
public class tester {
  public static void main(String args[]) {
    try {
      PrintWriter out = new PrintWriter(new FileWriter("tmp.txt"));
      java.util.Random rand = new java.util.Random();
      for (int i = 0; i < 20; i++) {
        out.println(rand.nextInt(10));
      out.close();
    } catch (IOException ioe) {
      ioe.printStackTrace();
}This will compile and run. Notice how you have declared your Random class using java.util.Random? You could have imported java.util.* or java.util.Random then used the declaration 'Random rand = .....' instead (like how i've declared the PrintWriter).
