OKay I have this program, The problem is I don't know what the idea of the seed value is? I have a rollDice Method and I want to Simulate the rolling of two dice and then add them together and then print out a result. The result is the result of the two random dice being rolled and then added together giving me a random number. Now what I want to do is with the GetMean Method, I want to Check to see and Find the mean, That is However many times the method RollDice was called I want to store that number into the index value in getMean, I then want to divide the rollDice number by the index? Is this possible? I'm just really stuck here, ANy Helps, Hints, Tips appreciated, Thank You!

/**

*/
public Histogram( long seed )
{
randomGenerator = new Random(seed);
int r = randomGenerator.nextInt();
}

public int rollDice()
{
int result;
int roll = randomGenerator.nextInt(6) + 1;
int roll2 = randomGenerator.nextInt(6) + 1;
return result = roll + roll2;
}

public double getMean()
{
int total = 0;
for(int index = 0; index < rollDice(); index ++){
total = rollDice() / index;
// total = rollDice();
}
return total;
}
//public double getMedian()
//{

/**

public void displayHistogram()
{
HistogramUI histogram = new HistogramUI( "Dice" );
histogram.setMax(rollDice());

histogram.setRollCount(2, 12);

histogram.setMean(getMean());

histogram.setMedian(3.2);

histogram.setMode("23");

histogram.setVisible();
