Slot Machine Java Code While/for Loops
- Java Tutorial
For my latest lab in Intro to Computer Programming, my partner and I coded a slot machine program in Java. Took a couple hours but the program is up and running. Realize I made a few errors in. The user prompt string suggests that capital letters should be entered, but the code only checks for lower case. CardValue is not necessary if you use enums; isBlackjack is breathtakingly complex. Using enums will fantastically simplify this code.
- This is done by firstly creating a file called Slots.java that will contain only the code for the UI. Then, creating an ActionListener that will listen to different button clicks (there are 5 different buttons). Finally, creating a class called App.java that will only create a Slots instance and make it run. Basically, the App.java would look.
- Broadly classifying, there are three types of loops in Java programming which are: 1. While loop makes it quite easy. Let's first look at the syntax of while loop.

A for loop is a repetition control structure that allows you to efficiently write a loop that needs to be executed a specific number of times.
A for loop is useful when you know how many times a task is to be repeated.
Syntax
The syntax of a for loop is −

Here is the flow of control in a for loop −
The initialization step is executed first, and only once. This step allows you to declare and initialize any loop control variables and this step ends with a semi colon (;).
Next, the Boolean expression is evaluated. If it is true, the body of the loop is executed. If it is false, the body of the loop will not be executed and control jumps to the next statement past the for loop.
After the body of the for loop gets executed, the control jumps back up to the update statement. This statement allows you to update any loop control variables. This statement can be left blank with a semicolon at the end.
The Boolean expression is now evaluated again. If it is true, the loop executes and the process repeats (body of loop, then update step, then Boolean expression). After the Boolean expression is false, the for loop terminates.
