If you test on the color RED in RGB:
Input: (255,0,0)
Output: (0,100%,100%)

Generate QR Code From Input Text And Display Information About Input / Output Bits

Nov 12, 2014

I am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.

// QR Code Generator
package qrcode;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.border.EtchedBorder;
import javax.swing.border.TitledBorder;

Aug 25, 2014

I'm having some trouble with getting this program to read an input of morse code and then produce an output of English. When typing in morse code for the phrase 'the string', the output looks something like this:

- .... .
t
h
... - .-. .. -. --.
s
t
r
i
n

The English-->Morse works just fine.

import java.util.Scanner;
public class project1

Output Of Code Showing Different Value?

Jan 13, 2014

I have one code [taking from on line SCJP exam preparation site]. I have 2 question in my mind:

1) addValue() is non static method then why it is running without object inside constructor. By this rule it should show compilation error.
2) With ref variable of parent always non overridden methods of parent run then it must value of 10 [If i forgot 1st point ]

But it is giving 40. Code is as below:

class Base{
int value = 0;
Base(){
addValue();
}
void addValue(){
value += 10;

Example input: "Therefore, it is this word."

output: therefore

It currently uses 3 loops nested loops, is there a way to improve this?

Web Services :: Code Implementation Generated By Axis2 Code Generator?

Aug 23, 2010

I was a bit confused of the code generated by the Axis2 Code Gen.

I have created a logIn(String username, String password) method in my service and used Axis2 Code Gen to generate the Stub.

I try to access the logIn method from my Client using the Stub like below:

TestServiceStub stub = new TestServiceStub("http://localhost:8080/axis2/services/TestService");
String test = stub.logIn("user","pass").

but instead of UserName and password as the parameters, the Stub created a Login object as the parameter for the logIn method. like the one below:

stub.logIn(Login login1);

I wanted to try the logIn method by providing a static userName and password but it seems impossible because the Stub changed the parameter for the logIn method.

how to test the logIn method.

int digit;
int base=2;
int degree;
double decimal;
int binary_zero=0;
int binary_one=1;
//create scanner for object input

Java Code That Ask User For Password Input

Jul 21, 2014

This is the java code that I wrote for a password:

// java application that asks the user to enter a password
 import java.util.Scanner; //program uses class scanner
 public class password{
//main method used to execute java application
public static void main(String args[]){
//create scanner to obtain input from command window

[Code] ....

here is the output of the code when I run it :

entered the passwordreason
Try againPress any key to continue . . .

The code compiles without errors. The problem is when , I entered the actually password that I declared in my code, it doesn't output "You entered the correct password" but it instead outputs "Try again", which is supposed to be the output if you've entered the incorrect password. What did I do wrong?

Code Storing Input Data In All Three Of Product Objects?

May 7, 2014

My problem is that in my program, I have the user input data for one of three product objects, however when I read the data for all three objects, the same data is stored in all of them.

Anyway this is the method from the Interface class:

private void readInput() // the only method in the program that accepts product data from the user {
Store matesStore = new Store();
String name;
int demandRate, productChoice;
double setupCost, unitCost, inventoryCost, sellingPrice;
Scanner console = new Scanner(System.in);

[Code] ....

And here is the method from the Store class:

public static void addData(int option, String newName, int newDemand, double newSetup, double newUnit, double newInventory, double newPrice)
//sets the product data for a particular product {
if (option==1) setData(product1, newName, newDemand, newSetup, newUnit, newInventory, newPrice);
else if (option==2) setData(product2, newName, newDemand, newSetup, newUnit, newInventory, newPrice);
else /*(option==3)*/ setData(product3, newName, newDemand, newSetup, newUnit, newInventory, newPrice);

[Code] ....

The problem I had was with static variables and methods.

Write A Code That Allows A User To Input Number Of Stones In A Basket

Nov 20, 2014

I am trying to write a code that allows a user to input the number of stones in a basket, then put the stones in my pocket, after the stones are in my pocket, the stones must be taken out, one by one, and thrown in a pond. I get stuck at this part because my for statement has to subtract the number of stones in my pocket (one at a time) and add a stone to the pond (one by one) at the same time.I can get the pond stones to increase until the max amount of stones with the following:

for (int i = 0; i < stones; i++) {

System.out.println("Pocket:" ? " " + "Pond:" + i);

how to reduce one and add to other. Is it possible to do this in one for statement? I tried to put stones-- in place of the question mark, but that is not working.

Or isn't it possible changing the color of output elements?

Input And Output Via JTextField

Jun 29, 2014

How would I display certain output text if the text entered equaled "text".

So lets say you enter a question into a JTextField. You press a button that submits the text. The output displayed depends on what the question you asked was.

Think about it as "If question = What color is the sky? On submit, display text "Blue". How to implement this.

Why Should Swing GUI Code Be Placed On EDT

Oct 3, 2014

According to what I read, "when programming in Swing, your GUI creation code should be placed on the Event Dispatch Thread (EDT). This will prevent potential race conditions that could lead to deadlock." (See below for code.)

Why is this? How could making a GUI lead to deadlock?

public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();

Code To Go From One Web Page To Next

Apr 24, 2014

I have a assignment in which the code has to scrape a web page for a little bit of data including the link to the next page, follow the link, and do this 100 times. It is scraping all the data correctly, including the link, but it isn't following the link to scrape the data on that next page. Instead, it is displaying the first page's data 100 times. I have the code in a while loop where it reads in one character at a time from the page into a string and then uses pattern matching to get the data and the next link from the string. Then it correctly displays the data and should loop back to connect to that next link and read one character at a time into the string and so on.

I have printed the link to the console and it is good. I don't get any errors. I just can't figure out where exactly the problem is. Here is my code:

import java.awt.*;
import java.io.*;
import java.net.*;
import java.util.regex.*;
import javax.swing.* ;
public class SimpleWebSourceGetter{
static void getSourceCode(String url) {
String mystring = "";
