The following java for-loop exercises have been collected from various internet sources such as programmr.com and codewars. Go to my tutoring page if you need more help and would like to talk to a tutor.
In this Instructable, the default package is what will be used. Inside of your project package, create two classes: Main.java, and TTT.java. Main.java will host the main method and will be used to run the code in TTT.java. TTT.java will contain a Tic-Tac-Toe object that contains the state of the board and methods to manipulate the game. 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. Flow Diagram Example. Following is an example code of the for loop in Java. Aug 22, 2014 On this post, let's take a look at how beginners of Java programming can make a simple, yet fully functional slot machine. Slot machines have been around for a long time, but its entertainment value doesn't seem to fade one bit.
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
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[]) . Merlin's magic slot machine free play.
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)
This is a code wars kata. click here to train on 'Abbreviate a Two Word Name' on code wars.
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:

Slot Machine Java Code While/for Loops C++
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!
