OK, trying this now. Still not quite right....
The instructions were:
A class named orderEntry should also be created with the appropriate
constructor, accessor and mutator methods. As the user is entering the
items they wish to order, these items should be placed into a separate
array as they are ordered. Once the user is done entering items, the
program should use the array to output all items that were ordered to
the screen, with their prices.
This is not a solution i would recommend, but for the sake of learning how to use methods:
just put it in another class and call the method from there. Give the methods the parameters needed.
public class whileMethod(String quit, double listTime, double listMax, Scanner input, double priceAdd, ArrayList<String> buyItemList, ) {
while (quit != "done" || listTime <= listMax)
{
System.out.println("Please enter item " + listTime + " :");
itemEntry = input.nextInt();
if (itemEntry == 1){
priceAdd = spagPrice;
buyitemList.add("Spaghetti Tacos");
}
else if (itemEntry == 2){
priceAdd = ramenPrice;
buyitemList.add("Ramen Pizza");
}
else if (itemEntry == 3){
priceAdd = pepperPrice;
buyitemList.add("Stuffed Bell Pepper");
}
else if (itemEntry == 4){
priceAdd = steakPrice;
buyitemList.add("Mushroom Steak");
}
else if (itemEntry == 5){
priceAdd = tunaPrice;
buyitemList.add("Tuna Suprise");
}
else {
priceAdd = 0;
}
buyList.add((int) priceAdd);
listTime += listTime;
}
From here u can call the method in the class:
whileMethod(and all the attributtes needed)

I'm trying to make a random deck generator for HearthStone and something is wrong with card[] array. It gives me null pointer exception and the first time it occurs is in the readFile() method, the debugger says the problem is with this line (well it starts there anyway) card[a].setName(name);. I know that it isn't the String variable "name" because I can reference that in a System.out.print().
p.s. my compiler is netbeans IDE 8.0.2

}
}
I have got it working so that it keeps count of the games won and lost, as well as assigning a score based on the amount of attempts/lives saved but I haven't been able to find a way to get it to keep a total score for all of the games played. Each game unfortunately has a seperate score. If anyone can advise me on a way of doing this, it would be greatly appreciated.
Create an int totalScore variable where winCounter, loseCounter and score are defined. Then increment it after each call to scoreGame()
score = scoreGame(attempts);
totalScore += score;
System.out.println("Your score is: " + score);
If you want to permanently save statistics between sessions then it's a whole nother story. You would need to write your scores to a file after each round and then start your program by reading this score file. It's hardly impossible, but requires a bit more code.

1. Everything seems to run fine up to this point, then checkout repeatedly runs a couple of times.
2. I don't know if the problem is how I'm calling upon checkout() or if it is within checkout itself:
if (func == 4);{
checkout();
}
if (func >= 5){
println("Error: do not know " + func);

}

continue;
else println(product[i].amount + " count of " + product[i].name + " # " + product[i].price

subtotal += (product[i].amount * product[i].price);
}
if (subtotal >= discountAmt){
disc =(discount * subtotal);
total = subtotal - (disc);
}
3. These printline statements are what are running repeatedly. My method not these println statements are contained within a loop so I don't know what could be causing this issue.:
println("Thank you for coming!");
println("Sub Total: $" + subtotal);
println("-Discount: $" + (disc));
println("total\t: $" + total);
}
public void setName(String name){
this.name = name;
}
private void setPrice(double price) {
this.price = price;
}
private void setAmount(int amount) {
this.amount = amount;
}
}
Actually the if statement is an empty control flow. The checkout method is not getting called as intended by you. Please remove the first semicolon.
if (func == 4);{
checkout();
}
I have 2 files, one of which request user input, and one of which returns array values based on user input. I'm having an issue returning my array. I'm only receiving specific elements within each array, although I'd like to return the whole thing. Do you see what I'm missing? Thanks.

does only return the element on position 5/2. If you want to return the whole Array it should be like
public String [][] getService() {

So my code works completely; the only thing now is a very simple problem that I cannot figure out. I have to make the program loop back to the beginning if the user type restart and I cannot think how to that.

there are two solutions.
1. wrap your code in "while" loop. but it will be difficult for you because your code is so messy :(
change the code as follow
