Hi,

I'm new to java, I'm taking a class now but I'm totally lost in the class.. I'm really struggling.. and am in seek of some assistance.. The teacher has assigned a project and I do not know where to start.. I'm new to this forum so please forgive me if I break any rules for posting..

Any ways the project that was assigned to me is due tommorrow.. and I forgot about it till now..So any help would be greatly appricated...

Heres the project:

simulating throwing a die and counts the frequency of each possible outcome: 1 though 6...and also compute the ratio of each outcome occurrences divided by the total of throwings


Again thanks for your help !

I'm sure nobody here wants to give too much away since this is a homework problem, but I imagine you know that you will need to simulate the die throw by generating some random numbers, and collect some statistics on the outcomes. Look at java.util.Random to start, and its nextInt(int n) method.

Let us know where you get stuck. It's going to look something like:

...

int numberToThrow = 100;
Random rand = new Random();
int[] count = {0,0,0,0,0,0};

for(int i = 0; i < numberToThrow; i++) {
    nextRoll = rand.nextInt[6]; // number 0-5 which we pretend is 1-6
    count[i]++;
}
System.out.println("Number of times 1 was thrown: " + count[0]);
System.out.println("Number of times 2 was thrown: " + count[1]);
.....
System.out.println("Percentage of times 1 was thrown: " + count[0]/numberToThrow);
...
