Easy java programs to make

Write a program that demonstrates the Circle class by asking the user for the circle's radius, creating a Circle object, and then reporting the circle's area, diameter, and circumference.

We'll also avoid animations, excessive styles, and anything else that will distract from the JavaScript quiz. This tutorial assumes a basic understanding of JavaScript. If you're not there yet, I've put together a JavaScript road map to get you comfortable with practical concepts quickly.

If you look closely at the JavaScript structure, you'll see that our generateQuiz function contains helper functions to show the quiz, accept submissions, and show the results. The general idea: For each question, show the question along with all of its answer choices.

Read through the comments in this code to see how it works. Note that in this line, the questions and quizContainer values will come from your generateQuiz function. The nice part about our code is that it works for any number of questions or answer choices you might have in your JavaScript quiz. We used the operator, which means 'or' to basically say 'Give us the selected answer OR if there's not one, then just give us an empty object.

Tip: Once your HelloWorld program has been successfully compiled, you will see a new file in the same directory. This is the compiled version of your program. In the terminal window, type the command :.

When you press Enter, the program runs and you will see "Hello World! Well done. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content.

For now, ask the player if they'd like to go first and store their option inside of a String variable. That should be good for now. Let's figure out what happens once the player has decided to go first or not.

We know that our Java game now has to keep going until the last stick has been taken. This means the rest of our code is going to be inside of a loop, specifically a while loop. Now, either the computer will make a move first or the player will, depending on who was chosen to go first by the player. So, we'll need an if-else statement. If the player goes first, we'll ask the player to pick sticks, and then the computer, otherwise it will be the other way around.

So now, our code should look like this:. You can test to see if this part of our Java game works by adding in a System. Note that your code will not ever stop running! Because remember the while loop we added; it will only stop looping when the number of sticks is equal to or less than zero! Let's create the 21 game for when the player goes first.

We won't worry about the other way around yet, since if we can do it this way, making the game go the other way is easy! Since the player is going first, we need to let him or her know how many sticks there are left.

Then, we want to ask how many sticks they'd like to take, either one or two sticks. Then, get the input and subtract that many sticks away:. From here, two things can happen. Either the player took the last stick, or it's the computer's turn to take sticks. That means we once again need an if statement. Remember that any time there are two or more possible ways your program can go, you need to use an if statement. So, how do we check if the player took the last stick?

Inside the else part, we want to make the computer take its turn. Here we'll use some simple artificial intelligence in order to make the computer decide how many sticks to take.

Our computer's logic will be simple: if taking two sticks makes it lose the game, or if taking two sticks leaves some multiple of three left, then only take one, otherwise take two. It's not so important to understand this logic, but we'd like the computer not to play too poorly else our small but fun Java game may not be as much well, fun.

You can try out the game for yourself later to see if you think the computer is too easy. Last, we want to tell the player how many sticks the computer took, and then we also want to subtract the number of sticks it took. If the computer took the last stick, the player wins!
