How do you unbox?

I see. I'm looking at the API and I don't see any other method that can find a duplicate. Is there another way?

I tried using Vector<Integer> but I'm still having problems matching the sum to every value in the container.


public static void main(String[] args) {


Vector<Integer> sumArray = new...

I was thinking the same thing about closing off the first for loop. The way I have it, the for loop is checking the current sum against each previous sum for a match, except on the first roll there...

Still not working. I have:


for (int k = 0; k < sumArray.length; k++){

for (int j = sumArray.length - 1; i < j; j--){

if...

Thanks for the reply. I tried this code but it still has the sum equal to the value in the index. I see where you're going here in the linear search going backwards. Great idea. Now I just need to...

You are correct. Forgive the confusing sentence. I meant that the value inside each index is equal to the sum.

The code does compile and run. That particular module is what I thought was a linear search through the array. I used some println statement to see what's happening in the run. It looks like the sum...

Hi all,

I'm having a problem using a linear search to find a duplicate. Here's the details of my program:

I roll two dice continually and get random numbers, 1-6. If I roll two of the same...

I'll try that out. Thanks!

Sorry for the confusion. It's pretty much how you just explained it but it's according to each customer's transaction time and the total simulation time you set. You can set the total simulation time...

Ah, that's in the "CheckoutArea" file. Second one down from the previous post. All of the events are handled there, from cashier free to busy, to customer waiting and being served, to setting up the...

Absolutely. First, you enter all of the required fields that the program is asking for (total simulation time, max transaction time, chances of a new customer entering the queue, number of cashiers,...

Hi all,

I've been working on this project for the past week and feel like I'm almost done. I've worked through most of the bugs but one is escaping me. The program is a Checkout Area Simulator for...

Hey all,

Just googled for a Java help forum and this one popped up. I'm a CS student in San Francisco and have a passion for programming. I'm a beginner, but am looking forward to learning all I...
