A basic Java guessing game I made to show you how it could be done. You can specify the amount of numbers to guess and shows the total guesses you made to guess the correct number.

I've commented out the "continue" part because I'm too lazy to fix the small error that but if you uncomment the code you will see whats wrong. I suppose i'll fix that later.

Anyway here's the code:

Output:

Welcome to the guessing game, guess the correct number!
By: HappyFace - www.engineeringserver.com :: v1.0 initial release

Legenda:
+ means higher
- means lower
! means correct

How many numbers you want to guess? 4

Secret number is: 6303
Alright, the secret number(s) are generated!

Guess the secret number: 6303
6! 3! 0! 3!

Concratulations! the secret number is indeed 6303
Total tries: 1

//edit
Oh and before I forget to mention it.. to disable the secretcode that shows on the screen just change "debug = true" into "debug = false" and the secretcode won't be visible.

Here's a demo I wrote some time ago to read a file and output it in the console. I've created 2 versions. One that uses the "Scanner object" and the other the "BufferedReader object" to read the text files from disk.

Both examples of mine work, but the Scanner version is preferred.

BufferedReader version:

Scanner version:

Here is a sample code I wrote to input and output text in a console. This is useful if you want input in your application.


public class ScannerDemo {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.print("Input: ");
String text = sc.nextLine();
System.out.println("output: " + text);
sc.close();
}
}

Output:
Input: This is some input text that i typed
output: This is some input text that i typed
