Rolling Java

Rolling Java is a game of luck. If the user rolls:

• 6: the game stops.

• 4: nothing happens.

• anything else: 1 point.

The user wins if they collect at least 3 points before the game ends.

Task 1

• First, print:

"Let's play Rolling Java. Type anything to start.\n"

• Print the rules:

"Great, here are the rules:\n"

>> - If you roll a 6 the game stops.

>> - If you roll a 4 nothing happens.

>> - Otherwise, you get 1 point\n.

>>You must collect at least 3 points to win. Enter anything to roll:

The last line implies the usage of Scanner because it needs to give the user time to read the rules.

Task 3

Make a while loop that runs forever.

Place your last scan.nextLine() as the first line in the while loop. In the second line, print "hey" for now:

Remove the "hey" print.

Task 4

Define the rollDice function.

/**
 * Function name: rollDice
 * @return randomNumber (int)
 *
 * Inside the function:
 *  - return a random number between one and six. 
 */

Task 5

During each run, call rollDice() and store the value in diceRoll. Print each dice roll: You rolled a <diceRoll>..

Task 6

During each run:

• If the user rolls a 6:

  • print: End of game.

  • stop the game.

• If the user rolls a 4:

  • print: Zero points. Keep rolling.

• If the user rolls anything else:

  • update the points variable by 1

  • print: One point. Keep rolling.

Test your print and println skills by trying to achieve a similar output:

Task 7

After the game ends, check the user's points.

• If the score is greater than or equal to 3, print:

  • Wow, that's lucky. You win!

• Otherwise, print:

  • Tough luck, you lose :(
