Character ammount |

I've just finished watching your tenth "Learning Java" part and I want to limit the character number to five digits only.Â
I've tried this:
Code: import java.util.*;
public class digitExtractorTester {
static Scanner userInput = new Scanner(System.in);
public static void main(String[] args){
String rNumber = "12345";
System.out.print("Enter a custom, five digit number: ");
String nSequence = userInput.next();
System.out.println(" ");
if (nSequence.chars() != rNumber.chars()){
System.out.println("Your input contains too many or too less digits.\nOnly five digit numbers are allowed.");
}
else{
digitExtractor byMath = new digitExtractor(Integer.valueOf(nSequence));
byMath.returnNumberSequenceByMath();
System.out.println(" ");
digitExtractor byChar = new digitExtractor(nSequence);
byChar.returnNumberSequenceByChar();
}
}
}
But it doesn't seem to be working. Any suggestions?
Never mind. I solved my own problem.
If anyone's wondering, I was using chars() when I was supposed to be using length(). (Source of information)
Code: nSequence.length() != rNumber.length()

Krypton Toolkit Download |

It has come to my attention that the Krypton Toolkit (ComponentFactory) is no longer available for download. Instead, the page simply contains no download link.
In the past, certain components of the software were free, while others were free for a limited number of days. In order to continue using the software indefinitely, a license key is needed.
Since the files are no longer available from the ComponentFactory webpage, here is the link to 4.4

(Apologies for the file provider.. it's a pretty big file)

Adding backgroundcolor to snake applet |

Hi guys,
first, i'm not the best english speaker and -writer. Therefore i ask you to apologize my language mistakes
Problably in your eyes, i have a very simply problem, but i cant add the background function to Brandonio's Snake Project. I want to have a black background in the applet. After this, i want to change the color of the grid to white.
I try to add two JPanel's to snakeApplet.java. But is it still not working. Every time i started the Applet, the background is white.
Code: import java.applet.Applet;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import javax.swing.JPanel;
public class snakeApplet extends Applet{
private snakeCanvas c;
JPanel jp1 = new JPanel();
JPanel jp2 = new JPanel();
public void init()
{
jp1.setBackground(Color.BLACK);
add(jp1);
jp2.setBackground(Color.BLACK);
add(jp2, BorderLayout.SOUTH);
c = new snakeCanvas();
c.setSize(new Dimension(640, 480));
c.setPreferredSize(new Dimension(640, 480));
c.setVisible(true);
c.setFocusable(true);
this.add(c);
this.setVisible(true);
this.setSize(new Dimension(640, 480));
}
public void paint(Graphics g)
{
this.setSize(new Dimension(640, 480));
}
}
In addition, i want to add music to the applet. The music should instantly playing if the applet is open.
If the idea of the black background and white grid is not to be a looker, than i would to add a picture in the background of the grid.
But i dont know how i can code it.
I hope someone can help me please
Yours sincerley
Kevin

Using a string as an alias/nickname |
Posted by: strawman83 - 06-04-2015, 09:12 AM - Forum: VB.NET

So part of the application I am building is a user blog, where the user can submit new blog entries or view previous entries. I've managed to write to/read the blog entry to and from a text file, with a 9 digit date format in front of the entry.
The problem I am having is that when I am loading the previous entries into a comboBox, it is loading all the text from the blog into each item of the comboBox.
What I want to do is load the date of the blog into the comboBox only, and when the user clicks on said date the entire blog text file is loaded into a textBox.
In the code below, I really need the blogAlias string to act as alias/nickname in the comboBox for the actual blog text. But I can't figure out how to do it.
Code: 'Fill comboBox with array of previous blog entries
While j < blogLineCount
     blogAlias = blogArray(j).Substring(1,9)
     comboBox1.Items.Add(blogArray(j))
     j = j + 1
End While

Hello. Nice site.
I just recently viewed on of the BP youtube tutorials on how to get all the files from a certain directory.
I was wondering if there was a way of amending it so that every line of every text file in a directory could be stored into an array?
Thanks.

Knuth Numbers recursion |
Posted by: Miriam - 04-21-2015, 11:46 PM - Forum: Java

Hello,
I recently had a final exam on which my teacher asked to write a method for Knuth numbers recursion. I got a stack overflow on my implementation, and I am new on Java, so I am not sure what happened, it might be that I had the wrong formula for Knuth numbers? I would love some feedback.
Here is the question, and my code
Knuth numbers are given by the recursive formula Kn+1 = 1 + min (2 * Ka, 3 * Kb) where a is the smallest integer larger than n/2.0 and b is the smallest integer larger than n/3.0. The use of doubles in the denominator is necessary to ensure that integer division is not used.
For example, if n is 7, then a equals 4 and b equals 3 and thus K8 = 1 + min (2* K4, 3 * K3).
If n is 8, then a equals 5 while b remains 3 and thus K9 = 1 + min (2 * K5, 3 * K3).
If n is 9, then a remains 5 while b equals 4 and thus K10 = 1 + min(2 * K5, 3 * K3).
Mathematically, “the smallest integer larger than x†is the “ceiling†function. If n is an int, then n / 2 is calculated using integer division, discarding the remainder; but you want the division to give you a double. Thus you need code that looks like this:
int a = Math.ceil(n / 2.0);
int b = Math.ceil(n / 3.0);
Since the equation defining Knuth numbers is a recursive one, we must have a base case; let’s assume that K0 = 1.
Create and test a class called KnuthNumbers (in a project also called KnuthNumbers) which includes a static method to compute Knuth numbers.
my code:
Code: public class KnuthNumbers
{
  /**
  * Recursive Knuth Numbers 1, 3, 3, 4, 7, 7, 7, 9, 9, 10, 13, ... Â
  */
  public static int knuthNumber(final double n)
  throws DataFormatException{
    double a = Math.ceil(n / 2.0);
    double b = Math.ceil(n / 3.0);
    // bad input
    if (n < 1)
      throw new DataFormatException("n cannot be less then 1");
    if (n > 12)
      throw new DataFormatException("n is too large. Max is 12");
    //base case
    if (n == 1)
      return 1;
    //recursion
    return knuthNumber(a + b);
  }
}
TEST:
Code: public class KnuthNumbersTest
{
 Â
  @Test
  public void testKnuthNumber(){
    long startTime = 0;
    long endTime = 0;
    double result = 0;
    try {
      assertEquals(-1, KnuthNumbers.knuthNumber(-3));
      fail("number should not be negative");
    }
    catch (DataFormatException e){
      assertEquals("n cannot be less then 1", e.getMessage());
    }
    catch (Exception e) {
      fail("Unexpected exception: " + e.toString());
    }
    try {
      assertEquals(0, KnuthNumbers.knuthNumber(0));
      fail("number should not be zero");
    }
    catch (DataFormatException e){
      assertEquals("n cannot be less then 1", e.getMessage());
    }
    catch (Exception e) {
      fail("Unexpected exception: " + e.toString());
    }
    try {
      assertEquals(1, KnuthNumbers.knuthNumber(1.0));
      assertEquals(9, KnuthNumbers.knuthNumber(5.4));
      assertEquals(13, KnuthNumbers.knuthNumber(7.6));
    }
    catch (Exception e) {
      fail ("Unexpected exception: " + e.toString());
    }
  }

C Tutorial Series |

So I have been thinking about doing a C tutorial series for quite some time now. In my opinion, C is the ultimate programming language. It's fairly low level (It compiles straight to assembly), it runs fast, it has decades of improvements built into it, and tons of community support.
Basically, C is used for most system programming. That is, if you want to make a utility for your operating system, you would usually do it in C. Of course, a lot of things these days are also written in C's self-deemed successor, C++. For instance, take the following programs:
Linux - C
Windows - C/C++/C#
Mac OSX - C/Objective-C
All of which are written in C or its many variants. Because of this, I think it is important to make a C tutorial series that will also lead into C++, since the two are fairly related. The C portion of the tutorial will be based on the K&R, so people can easily follow along if they own the book.
What are your guys' thoughts?
