Slot Machine Java Code While/for Loops
In main, the while (b!= 0) loop would best be written as a do-while loop, since you want to run the game at least once without asking. B is a poor variable name; playAgain would be much more helpful. The main lesson that I think you should learn from this exercise is object-oriented thinking. Java Slot Machine Loop. Problems in your code: for every iteration of the loop the userTotal is 100.00-userBet1. 'While similar questions may be on-topic.

User input does not work with the embedded compiler (paiza) below. That is why you see the problems being worded and setup slightly differently than on the rest of the page.
Happy Coding!
Exercise 1:
Determine and print the number of times the character ‘a’ appears in the input entered by the user.
Exercise 2:
Write a program that will print a box of #’s taking from user the height and width values.
Exercise 3
Slot Machine Java Code While/for Loops Tutorial
Write a program to find the sum of 5 integers.
Exercise 4
Write a java program to calculate the factorial value of given number. Factorial x –> x * x-1 * x-2…x*1
Example: factorial 4 = 4 * 3 * 2 * 1 = 24
Exercise 5
Suppose we have a database composed of two fields or columns (arrays), the first field is for the username (user[]) and the other one is for the password(pass[]) .
This is how it looks like:
user[0] = “Hassan” ;
user[1] =”Idris”;
user[2]=”Trevor” ;
And their passwords correspond with their indexes.
pass[0] = “homecomingking”;
pass[1] = “turnupcharlie”;
pass[2] = “afraidofthedark”;
Then if one of them had successfully login, the output should be:
Enter username: Hassan
Enter password: homecomingking
Hello Hassan!
But if not, “Incorrect Login!”
You can ignore case for the username but not for the password.
Exercise 6
You have to design the code such that the user has only three tries to guess the correct pin of the account. You set the pin as a constant with a final attribute. When correct display “Correct, welcome back.” When incorrect display “Incorrect, try again.”. When ran out of tries display “Sorry but you have been locked out.”
Exercise 7
Write a program that prompts user for a word and prints “Yes” if it is a palindrome and “No” if it is not.
Exercise 8 (Advanced)

Write a function to convert a name into initials. You can assume the program takes in two words with one space in between them.
The output should be two capital letters with a dot separating them.
It should look like this:

Write a method smash that takes an array of words and smashes them together into a sentence and returns the sentence. You can ignore any need to sanitize words or add punctuation, but you should add spaces between each word. Be careful, there shouldn’t be a space at the beginning or the end of the sentence!
