I have a web application on which "Hello There" is getting printed via a bean StringBuilder as follows.
StringBuilder sb = new StringBuilder();
sb.append("Hello There");
and in jspx I do see Hello There in black color.
I want Hello There to be in blue color. How do I do that ?
If I want to read from file the word "red" And then the following is not the right way like in the code ,, How to set the Color name
File inputFile = new File ("C:\input.txt");
Scanner scan = new Scanner (inputFile);
String RedColor=scan.nextLine();
Color backColor = new Color(redColor);
No problem setting background color for layouts, e.g. bdrPn.setBackground(new Background((new BackgroundFill(Color.BLACK, CornerRadii.EMPTY, Insets.EMPTY))));
But neither of the following are working for me, running JavaFX 8 on latest OS-X
scene = new Scene(bdrPn, winW, winH, Color.BLACK);
scene.setFill(Color.BLACK);
scene.setFill() worked fine for previous versions of JavaFX.
I've just started working on a program and i'm already having difficulties with the program. I can't get the background color to change from the basic gray color. Maybe you can tell me what i'm doing wrong.

also if theres any way to shorten up what I have there, that would be great.
So this application gets input from the user and converts it into a string. It then uses various methods to set instance variables of this class and ends up printing those classes to display information to the user about that products.
package javaapplication5;
import java.text.NumberFormat;
import java.util.Scanner;
public class Product
{
private String product;
private String description;
private double price;

I am getting a logical error. My output is this:

I am trying to align the core/middle side color of a cube, index 4, with the bottom middle color of the same side, index 7. (Each side has values 0-8 where 0 - is the top left corner, 1 is the top mid corner, 2 is the top right corner, 3 is the middle left corner, etc).
In addition to lining up those two colors, I am also making sure that the neighbor color of index 7(the color that it is attached), in this case the bottom color, matches with the top core/middle color. I will attach some pictures and a print out to show what I am talking about...
However, in my code when I am trying to align all of these up together, it does not go into the while loop. Each of the loops essentially is trying to get a match of same color with index 4 and 7, as well as making sure that index 7's neighbor color (the bottom color, in this case) matches with the top color.
Here is what I have tried:
private void alignSideColor(){//make the bottom colors neighbor match with a middle side value and rotate it to the top, for the top cross
if(cube.bottom.square[1].charAt(0) == topColor){
while(cube.front.square[7].charAt(0) != frontColor && cube.bottom.square[1].charAt(0) != topColor){
rotateBottomClockwise(1);
System.out.println("Trying to align side color...");
[Code] .....
The print out of the ELSE IF is:
alignment is: W-G and tops: R-R
NOW ITS ALIGNED
even though the sides, index 4 and 7, are NOT aligned with each other
I have also tried the same thing but with out the 2nd condition in each while loop, and although is DOES enter the while loop, it does not perform correctly -- index 4 and 7 WILL have matches colors, but it does not check to see if index 7's neighbor matches with the top color.
Here is how it prints out
** ** ** G7 B6 Y1 ** ** **//this portion is the back of the cube
** ** ** R6 W5 O4 ** ** **
** ** ** R3 W2 O1 ** ** **
B3 G4 Y9 W9 O8 Y7 W3 B4 G9//this portion is the left, top, and right of the cube
B2 G5 R8 W4 R5 Y6 O2 B5 G8
O7 W8 R9 B7 B8 B9 R1 R4 R7
** ** ** O3 O6 O9 ** ** **//this portion is the front of the cube
** ** ** Y2 Y5 Y8 ** ** **
** ** ** B1 G6 W7 ** ** **
** ** ** Y3 Y4 G1 ** ** **//this portion is the bottom the cube
** ** ** R2 O5 G2 ** ** **
** ** ** W1 W6 G3 ** ** **
Here is the cube showing the top, left and front side
Here is the left and bottom side. As you can see index 4, G5 -- yes that is a 5 lol -- does not have the same color as index 7, W8.
I need to rotate the bottom until W8 is aligned with a middle white value. An examples of a neighbor is: W8-R2

I am working on a chat programme and I was wondering how to separate the both usernames for example:
Server is me , and Client is the first man who had connected to me , so I want to be
Server to be in green color , and Client to be in Red
Server(green):Hi
Client(red):hello
Server(green):How you doin'
Client(red):Fine
My second question is both of em' to have minutes and dates for example
27.05.2014 11:30pm Server(green):Hi
27.05.2014 11:31pmClient(red):hello
27.05.2014 11:32pmServer(green):How you doin'

I'm programming in school using Netbeans and we've just started with graphical programming (i.e JPanel, JClass, JFrame). This is my first assignment and the purpose of this program is that when you press the mouse you will fill 4 circles with diffrent colors. I've managed to draw 4 circles with diffrent colors but I want my cursor to change color simultaneously. Here's my code so far ....
//Java klass "Klick"
public class Klick {
//Medlemsvariabler.
private int x = 0;
private int y = 0;
private int r = 1;
public int antal = Rityta.antalKlick;

Color only changes, when resizng frame with mouse, not when clicking.

I'm doing this project where I need to make a persian carpet using recursive methods. I already have my recursive what I'm trying to implement is the use of color. My method BorderColor draws a square using a random color choose from an array.
public void Cuadrado(Graphics g){
Random color = new Random();
g.setColor(colors[color.nextInt(colors.length)]);
g.drawLine(left, top, right, top);
g.drawLine(left, top, left, bottom);
[Code] ....
What I'm trying to do is getting the color from 4 different corners in order to create a new one and make a recursive call. I already tried using the method getPixelColor from the Robot() object but I quit it because is a recursive method and it may cause trouble with the recursive stack. I created this method to create the new color and then call it in the PersianRug method, but I dont have a clue on how to obtain and implement the new colors.
public int newColor(int c,int c1,int c2,int c3, int a){
int c4=((c+c1+c2+c3)%13)*a;
return c4;
}
The title says it all and i'm a fairly new java programmer but here is the code:
package TestVersion;
import java.awt.Color;
import java.awt.Graphics;

I think i need a variable or something oh and here is the 2 other classes, the keylistener one:
package TestVersion;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
[Code].....
how I can highlight one column with color? When i add color to a column the entire table is colored.
View Replies View RelatedThe Toys of the Future Company has decided to issue a new line of toy robots. While they are not sure exactly what their robots will look like, they do know the functionality that they will all have. All robots will be able to move forward, turn right, turn left, spin and detect an object in front of it via a sensor. The robot will use a touch sensor to determine whether it has hit an object in front of it, such as a wall. The robot will have two, three, or four wheels, but it will only be driven by two of them: a right wheel and a left wheel. Each wheel will be attached to a motor that controls it.
* ^ this is only something to think about
Produce a UML class diagram.
Using UML, describe the objects and classes that will be associated with this new toy. Either hand draw or use an appropriate UML creation tool to generate a UML design document for your Robot class. Create a set of classes that can be used to control the robot.
Develop your new class.
Create a new NetBeans project entitled, "Assignment_8_1" and develop your new class. Now, using the objects and classes that you have written, write a program for your robot that allows it to move in a large square. Allow your robot to run in a big two dimensional array and every time the robot encounters a square in your array, turn that square black.
So here is the code for the moving ball:
package ballapplet;
import java.awt.*;
import java.util.Formatter;
import javax.swing.*;
public class BallApplet extends JPanel {
private static final int BOX_WIDTH = 640;

I want to know how to change the color of an object, and how to move it in specific directions.
the program runs fine with exception of color background change.. dont laugh at code.

I've been using Java Advanced Imaging to convert tiff images to jpeg. The code I'm using is pretty simple, and I'll include it below:
Java Code: private static void convertImage(File tiff_src, File jpg_dest)
{
if (tiff_src == null || !tiff_src.exists()) throw new IllegalArgumentException();
try
{
SeekableStream stream = null;
[code]...
The problem when I run this code is that during conversion, the decoder or encoder seems to drop a good deal of black. I'd like to include examples, but the tiff images are about 30 MB...I've tried configuring the decode parameters, as well as the encode parameters, but like I said, somewhere during conversion I drop a good deal of the black from the image.
