    Question Random Letter problem please help!

    I've got a database of words which are held in an arraylist. I have created a getWord method which selects a word at random. The computer needs to select a letter out of the seleted random Word. At the moment it is selecting a letter from A-Z which is not correct. I would like it to select a letter from the chosen word, similar to hangman.



    private void chooseLetter() {
            boolean guessed=true;
            Random randomGenerator = new Random();
            char letter = (char) (randomGenerator.nextInt(26)+65);
            chosen=word.hasLetter(letter);

    Default Re: Random Letter problem please help!

    Took me some time, but I got it

    import java.io.*;
    import java.util.*;
     
    public class RandomLetter {		
     
    public static void main(String args[]) {
     
    Random generator = new Random();
    int RandomNumber = 0;
    int RandomNumberTwo = 0;
    String words[] = new String [3];
    words[0] = "TestForJavaForumsYahh";
    words[1] = "BigTest";
    words[2] = "Forums";
     
    //Generate a random number from 0-2
    RandomNumber = generator.nextInt(3);
     
    //Get the length of the randomly selected string
    int length = words[RandomNumber].length();
     
    //Generate a random number that is from 0-length
    RandomNumberTwo = generator.nextInt(length);
     
    //Print out a character from the random word selected
    System.out.println(words[RandomNumber].charAt(RandomNumberTwo));
     
    System.out.println(words[RandomNumber]);
     
    }	
    }

    This randomly picks a word from your word bank. Then it randomly picks a letter from the word and prints it out.
