True random generation in Java

Question

I was reading the Math.random() javadoc and saw that random is only psuedorandom.

Is there a library (specifically java) that generates random numbers according to

Answer 1

Quick and dirty:

public static int generateRandom() throws IOException
{
    int num = 0;
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

    for (int i = 0 ; i < Integer.SIZE ; i++)
    {
        System.out
          .println("Flip a fair coin. Enter h for heads, anything else for tails.");

        if (br.readLine().charAt(0) == 'h')
        {
            num += Math.pow(2, i);
        }
    }

    return num;
}
