Project #402594
Your Project
For your first project, you’ll create a simple number guessing
game. The game will use a for statement to ask for three
guesses and an if statement to determine if the answer is
right.
Instructions
1. In NetBeans, create a new Java Application project
named NumberGuess. Review Activity 2 for details.
2. In the main() method, add the code to generate a
random number:
int randNum = 0, guessNum = 0;
//Generates a random number from 1 to 10
randNum = new java.util.Random().nextInt(10) + 1;
System.out.println(“I am thinking of a number from
1 to 10”);
3. Using a for loop, ask for three guesses. See pages 23–24
in the textbook for more details. You can use the following
code to ask for a guess:
System.out.print(“Guess? “);
//Wraps the default input in a simple parser
called Scanner
java.util.Scanner scan = new
java.util.Scanner(System.in);
guessNum = scan.nextInt(); //Reads the next
command-line int
System.out.println(“You guessed “ + guessNum);
4. Using an if statement in the for block, determine
whether randNum and guessNum are equal. See pages
21–23 for in the textbook for more details. You can use the
following code if randNum and guessNum are equal:
System.out.println(“You guessed it!”);
break;
5. When you’re finished, the contents of the main() method
should resemble the following:
int randNum = 0, guessNum = 0;
//Generates a random number from 1 to 10
randNum = new java.util.Random().nextInt(10) + 1;
System.out.println(“I am thinking of random number
from 1 to 10”);
for (/* Figure this part out yourself */) {
System.out.print(“Guess? “);
java.util.Scanner scan = new
java.util.Scanner(System.in);
guessNum = scan.nextInt();
System.out.println(“You guessed “ +
guessNum);
if (/* Figure this part out yourself */) {
System.out.println(“You guessed it!”);
break;
6. Compile and run the project to ensure it works as
expected. To type input, make sure you click in the
Output panel; otherwise, you’ll modify code.
To submit your project, you must provide the following
two files:
■ NumberGuess.java
■ NumberGuess.class
