Variable Is Set Works / But Then In Void - Returns 0

Jun 13, 2014

The id variable is the problem Java Code: package com.cjburkey.games.boxee.objects;

import java.awt.Graphics;
import java.awt.Rectangle;
import com.cjburkey.games.boxee.GameState;
import com.cjburkey.games.boxee.resources.Images;
public class Block extends Rectangle {

[code]...

In the constructor, it returns corrent numbers, in the draw method, it returns 0. Why?

How DrawImage Works

Jun 14, 2014

I copied this right out of oracle almost. And yet it won't draw.

ImageIcon salt = createImageIcon("icons/bathsalts.jpg");
/**
* @Override
*/
public void draw(Graphics g){
 
Graphics2D g2d = (Graphics2D) g;
g2d.drawImage(salt, getX(), getY(), null);
}
 
 why draw image doesnt work for me. drawRect and circle are going just fine...
 
protected static ImageIcon createImageIcon(String path) {
try{
java.net.URL imgURL = ButtonPanel.class.getResource(path);
return new ImageIcon(imgURL);
} catch(RuntimeException e) {
System.out.println("Invalid file path");
}
return null;
}

App Works Locally But Not From Website

Feb 9, 2014

I have a Java application that was built by a third party and my task is to embed this in a web site. To do so I got an HTML snippet, a .JAR and da .DAT file that seems to be called by the app. I tested this locally on my machine and it works ok. After uploading to the web server I get an error message

NumberFormatException For input string: "i>>?<html>"(the question mark is actually upside down, the >> is really one character)

At first sight this looks like a common issue with UTF-8 file being delivered when the file itself holds only ANSI characters (or vice versa). So I made sure that the .HTM and the .DAT file are indeed stored in ANSI 8-bit (and not Unicode 16-bit) format. However, this does not solve the issue. The .HTM file itself also holds a ISO 8859-1 directive. The server is set to deliver UTF-8 by default. I cannot change this due to a huge lot of other dependencies.

So I am not sure if my suspicion is right - is it indeed a character set issue? Or is it something else?

The test file is on [URL] ....

Creating Array That Works Like A Torus

Mar 14, 2014

I have create a program that takes a random array which is created by starting from 0 and adding Math.random() (double between 0 and 0.999) n times, and calculates the weighted average of each position within a certain radius. I currently have a program that does this but i was wondering how to create one using a torus. The basic principle is the last element is now equal to the first element and when the first element updates its position it takes into account the difference between the other elements including some of the last elements in the array.

Heres the code so far that works for one iteration. After one the code is incorrect and calculates the wrong values. I think using a circular list or a ring buffer may work but i have little experience with either.

import java.text.DecimalFormat;
import java.util.Scanner;
public class Torus {
public static void main(String[] args) {
  DecimalFormat df = new DecimalFormat("#.###");

When To And Not To Use Void

Apr 9, 2014

I know void means it doesn't return anything but to me when I think it doesn't return anything it just does equations and other things. So why can you use this? Or is Void like returning input such as a Scanner?

void printStates() {
System.out.println("cadence:" +
cadence + " speed:" +
speed + " gear:" + gear);
}

Split String Function No Longer Works

Jun 23, 2014

I am encountering a problem while running this small piece of code.

public class TestSplit{
public static void main(String[] args){
String myWords[]="My.Home.Is.Being.Painted".split(".");
for(int i=0;i<myWords.length;i++)
System.out.println(myWords[i]+" ");
}
}

The problem is: it does not run at all. No error message is displayed. It just returns to the command prompt when i run it. Where am i wrong?

JavaFX 2.0 :: JFreeChart - When Zoom In Or Out Repaint Works Not Well

May 8, 2015

I have a problem using JFreeChart with JavaFX. I wrote a small program here . At first the graph likes this:

I use fullScreen function to display the JFreeChart Line Chart Demo 2. Here I use SwingNode, ChartPanel to embedded JFreeChart into JavaFX Panel.(Detail part will be included in code later)

Then I press ESC to exit fullScreen. Then it looks like this:

So far, it's as expected. Then I use mouse drag to enlarge the window. Here comes the problem, as the following picture.
 
Can you see that, seems like appear another graph. And I must click on the window, then everything will become good. I wish the graph shows well even when I drag the window to enlarge, is there something I missed? And here is my code:

package testxychart; 
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

[Code] ....

I think, when I use several graphs in one JavaFX Panel, this will becomes a big problem.

Using String In A Void Or INT?

Apr 20, 2014

I am trying to make a custom texture system for a block in Minecraft, I am not too advanced with Java and am not sure how to make this work the way I want it to.

Java Code:

/** The list of the types of step blocks. */
public static final String[] blockStepTypes = new String[] {"stone", "sand", "wood", "cobble", "brick", "smoothStoneBrick", "netherBrick", "quartz"};
private Icon missing;
private Icon icon1;
/**
* From the specified side and block metadata retrieves the blocks texture. Args: side, metadata
*/

[code]....

Alright, so basically I figured I could just tell the code to see if the block is made out of Stone, then to set the texture to Stone, or if it's made out of Sand, then set it to Sand.What I usually get is Eclipse telling me to "insert '!= null' check", "insert '!= null' check", and then just error out saying "Opperator != is undefined for the argument type(s) boolean null"

Assigning Int Literal To Byte Works But Not As Method Parameter

Apr 23, 2014

If you write

byte b = 100; it works (implicit conversion of implicit int literal 100 to byte.

But if you have a methodvoid bla(byte b){}

And want to invoke it with a literal (which is an int by default):bla(8) then there is no implicit conversion.

Is the byte b = 100; just an exception in Java? And is it the rule that one has to explicitely cast (narrow) integer literals when passing to smaller-than-int types?

Works In Netbeans / Eclipse But Doesn't Work After Being Compiled By Either

Mar 2, 2014

There is a specific function I have added to a program I've been working with for a while which involves retrieving data from a website. Here is that code:

Java Code: public String getWebData(String urlString, String add) throws IOException{
String output = "";
try {
//+s being the token, for example if dictionary.com was being used
add = add.replace(" ", "+s");
urlString = urlString + add;
URL url = new URL(urlString);
InputStream inputStream = url.openStream();

[code]....

Anyway, when I run this program within Netbeans, it works perfectly. I have a backup of the project in eclipse as well, and I've copied all of the code over and tried running the same thing in Eclipse - exactly the same, it works perfectly. The problem is whether I compile the the code in Netbeans or Eclipse, the exported runnable jar for some reason has an issue with this one method. It doesn't crash, and it seems to be doing something, but it is by no means giving me the data from the website like it is supposed to.

Working Through Printf And Void

Sep 1, 2014

I have a program that I have created from scratch called Product and I also created a Tester program to test my theory. The only problem that I have is that I am getting an error with this statement System.out.printf statement. The statement needs to print out "Program [name = HP ENVY x360 TouchSmart, price = $xxxxxx". The error states that "The method printf(String, Object...) in the PrintStream is not applicable for the arguments (String, String, void).

Which tells me that it is referencing back to the class file where I have

public void applyDiscount(double percent) {
percent = price - (price * percent); //establishing the discount
}

The lines of code in my tester file are (partly displayed)

String formatString = "Product[name = %s, price = %.2f]";
System.out.printf(formatString, product.getName(), product.getPrice())
//user input the discount amount
System.out.println("Enter discount percentage [0 - 100]: %.2f ");
double discount = user_input.nextDouble();
System.out.printf(formatString, product.getName(), product.applyDiscount(discount)); //This is the line giving me an error.
}
