I'm making a bare-bones Craps simulator with Java on the Eclipse IDE, I'm having a terribly hard time debugging the things that don't seem to indicate any errors in syntax only during the compiling process.
I'm running into this issue when trying to assign a value to the first bet on the "table."
The Pass()method isn't operating as I expected it would, I don't have any immediate error messages however it does not want to compile past this point, which is only line 33 down on the main method.
char answer = keyboard.nextLine().toUpperCase().charAt(0); This line seems to be the largest hurdle in getting all of my methods to operate smoothly throughout.. from what I understand.
I do have a die class but that's proving to be a non issue so I didn't include it in this post.
EDIT: This is the entirety of the program as it stands. I've been tweaking left and right on either end to find the appropriate ways to compile this absolute mess.
Any input is much appreciated. Thank you in Advance.

Java arrays are 0-origin. Basically, that means that the first element in arrays have an index of 0, not 1, as your dice array shows. Thus, you need to replace dice[1] and dice[2] with dice[0] and dice[1], respectively.
EDIT Based on new info from comments:
This sounds like a new error than the AIOOBE that you previously described. The issue with your code is that you need to ensure that you use Scanner's hasNextLine() method before calling the nextLine() method. Essentially, you are calling nextLine() when there is no "next line", causing the NoSuchElementException.

i'm trying to create a program where the number that the user has input would decrease by a certain amount. something that would like this:
Update by (Increment/Decrement):decrement
Enter starting number:15
Enter update number:3
Enter end number:3
loop#1 value=15
loop#2 value=12
the end number is where the loop would stop and the update number is how much the starting number should decrement by. so far this is the code I have and I'm stuck on how to keep the loop going until the end number.
package jaba;
import java.util.Scanner;
public class loop {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
Scanner input = new Scanner(System.in);
System.out.print("Update by (Increment/Decrement):");
String Decrement = scan.nextLine();
System.out.print("Enter starting number:");
String number = scan.nextLine();
System.out.print("Enter update number:");
String upnumber = scan.nextLine();
System.out.print("Enter end number:");
String endnumber = scan.nextLine();
int i,j;
i = 15;
j = 1;
do {
System.out.println("loop#" +j+ "\tvalue="+i);
j++;
}while(i<15);
i = i-3;
System.out.println("loop#" +j+ "\tvalue="+i);
};
}
how about something like this:
public class loop {
public enum Operation {INCREMENT, DECREMENT, INVALID}
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.print("Update by (Increment/Decrement):");
String operationString = scan.nextLine();
System.out.print("Enter starting number:");
String numberString = scan.nextLine();
System.out.print("Enter update number:");
String upnumberString = scan.nextLine();
System.out.print("Enter end number:");
String endnumberString = scan.nextLine();
// Determine and parse stuff
int startNumber = Integer.parseInt(numberString);
int updateNumber = Integer.parseInt(upnumberString);
int endNumber = Integer.parseInt(endnumberString);
// Parse operation, but assume invalid operation
Operation operation = Operation.INVALID;
if (operationString.equalsIgnoreCase("increment")) {
operation = Operation.INCREMENT;
} else if (operationString.equalsIgnoreCase("decrement")) {
operation = Operation.DECREMENT;
}
// now do the "meat" of the assignment
int loopNumber = 0; // we'll keep the loop number as a separate counter
switch (operation) {
case INCREMENT:
for (int i = startNumber; i < endNumber; i = i + updateNumber) {
loopNumber++;
performAssignmentPrinting(loopNumber, i);
}
break;
case DECREMENT:
for (int i = startNumber; i > endNumber; i = i - updateNumber) {
loopNumber++;
performAssignmentPrinting(loopNumber, i)
}
break;
case INVALID:
default:
throw new IllegalStateException("Please enter supported operation! (increment/decrement)");
}
}
private static void performAssignmentPrinting(int loopNumber, int value) {
System.out.println("loop#" + loopNumber + "\tvalue=" + value);
}
}
or the do/while version:
// now do the "meat" of the assignment
int currentNumber = startNumber;
int loopNumber = 0; // we'll keep the loop number as a separate counter
do {
loopNumber++;
switch (operation) {
case INCREMENT:
currentNumber += updateNumber;
performAssignmentPrinting(loopNumber, currentNumber);
break;
case DECREMENT:
currentNumber -= updateNumber;
performAssignmentPrinting(loopNumber, currentNumber);
break;
case INVALID:
default:
throw new IllegalStateException("Please enter supported operation! (increment/decrement)");
}
} while (currentNumber != endNumber);
you have i = i-3; out of loop.
Move decrementation of i into loop:
do {
System.out.println("loop#" + j + "\tvalue=" + i);
j++;
i = i - 3;
} while (i > endnumber);
For loop is the solution for your program. for(a ; b ; c) {...}
Google how a for loop works. And try to understand how the 3 parts a,b,c works.
Pseudo:
// if decrease mode
// for (i = upperbound ; i >= lowerbound ; i-= decrement)
// print i
// if increase mode
// for (i = lowerbound ; i <= upperbound ; i+= increment)
// print i
Update: This is sufficient to get you started and add more validation on your journey.

This is my code but I'm very new to coding. Im just trying to reset the variable that controls the amount of questions presented to the user to reset at the end of each loop. So far I'm unable to figure out what I'm doing wrong
There are a number of issues with your code that makes it difficult to trace / debug.
If I understand correctly, your outer doWhile is supposed to run indefinitely until user chooses to terminate the program.
The second doWhile is controlling the number of questions that are being asked in any single, complete round of the game.
Firstly, bring the 'numberOfQuestions' variable to be within the scope of the outer loop.
Secondly, you can simply declare a boolean variable to control whether the user wants to continue playing the game or to terminate the program.
Lastly, for each of the switch cases, you can simply do questionCounter++, instead of summing the correct and incorrect answers.
boolean keepGoing = true;
do {
int numberOfQuestions = 0;
int questionCounter = 0;
System.out.println("How many questions?");
numberOfQuestions = sc.nextInt();
do {
// ask questions repeatedly
// for each case, questionCounter++
} while (questionCounter != numberOfQuestions);
System.out.println("Enter '0' to continue");
if (input.nextInt() != 0) {
keepGoing = false;
}
} while (keepGoing);
It is also good practice to make sure your lines are indented properly, so that you are able to see what codes belong in which block for better maintainability and debugging.
I've been working on a slot machine program for class and have been having trouble figuring out how to compare the different "slots" on the machine to determine whether or not there are matches and tell the program how to proceed with calculate winnings. I originally thought of storing each result of my random number generator in a variable and then comparing them but am unsure of how to do this. I am unable to use arrays or lists or anything like that unfortunately. Thanks in advance and sorry if my code looks sloppy.

Use an int[] hits = new int[5]; array to store for each value how often it was selected. in the loop increment hits(slot) += 1;. Later, loop over the array to find the maximum.
How do I make amount() in class Casino.java store the total value and allow it to be returned to the class Roulette.java.
When I use:
int amount = Casino.amount();
It gives me several hundred lines of errors.
What I want done is to run the game number() and store the value into Casino.amount()
Please note in class Roulette.java there is a function called amountUpdate() which should update Casino.amount().

Looks like you're probably running into a StackOverflowException. When you call Casino.amount() inside of Roulette.number(), it then calls Roulette.amountUpdate(), which then calls Roulette.number(). Your methods are stuck in an infinite loop like this. You'll need to redesign your code such that these 3 functions are not all dependent on each other.
Your code is terse, so it's hard to help you fully solve the problem, but I believe you would benefit from splitting up your "amount" variable into separate entities. Keep things like bet amount, winnings, and such separate until you need to combine them.
Another issue you may run into is thatRoulette.amountUpdate() is called twice in Casino.amount(), but Roulette.amountUpdate() will not necessarily return the same thing both times. Consider storing the return value from the first call instead of calling it twice.
I'm more than 90 percent done with my code... Wanna add a few things but I've got no idea how to proceed.
This is my code so far... I have other classes as well, and I'm calling them in this code.

How would I do the following in my program?
Each iteration should display the readings being generated for each temperature and humidity. At the end your program should display a summary of the simulation as follows:
Season: _________ (if random, then display Random:Summer for example)
1- First temperature generated
2- Last temperature generated
3- Lowest temperature generated
4- Highest temperature generated
5- Total sum of all temperatures generated
6- Average for the season
Humidity Type: _________ (if random, then display Random:Full for example)
1- First humidity reading generated
2- Last humidity reading generated
3- Lowest humidity reading generated
4- Highest humidity reading generated
5- Total sum of all humidity readings generated
6- Average humidity reading
