My problem is that I keep getting the error in the title during debugging.
array[i] = java.lang.IndexOutOfBoundsException : Invalid array range 10 to 10
The following is the for loop. I entered values people = 10, payer = 4, rest = 6.
int[] array = new int[people];
Random rand = new Random();
int rest = people-payer;
for(int i=0; i<people; i++) {
if(payer<=0) { /*Payers are already decided*/
array[i] = 0;
continue;
}
if(rest<=0) {
array[i] = 1;
continue;
}
else {
int randomNumber = rand.nextInt(2);
array[i] = randomNumber;
if (randomNumber == 1)
payer--;
if (randomNumber == 0)
rest--;
}
}
I think the error is saying that I'm trying to access an index 10 of my array which doesn't exist. I don't know where I am accessing array[10]. Or maybe the problem is somewhere else??
Thank you for your time :)

This is the entire code but it's long so.. i don't know if it would help. The for loop is inside the onClick method.
