Swing/AWT/SWT :: Cannot Convert Unicode
Feb 26, 2014
Recently I switched a RCP/swing app from using hypersonic to mysql. The problem is that there are some unicode characters in the data. The data now displays with the unicode characters as unicode in the app. I tried printing out the data from the bean and it comes out the same way on the console. If I cut/paste the string from the console and place another print statement inside the bean I get output with unicode from the field and formatted output from the other print statment. Why???
public String getText(){
System.err.prinltn(text); //this is the actual value that comes in from the database
System.err.prinltn("u00e");//this is the cut/past value of what the above line prints except this shows in the console correctly
return text;
}

String pass= passordFelt.getPassword();
I could not cast it to String
String pass= (String) passordFelt.getPassword();
But I need that password to be String,cause i need it to be sent to getConnection(url,user,pass) where pass is a String type.

On a web application i can take a pdf cut it and convert it to html. As a result of this is that i can have my own design(Background) on HTML and then use it on jsp.
Is there a way to do this also in swing ? take a pdf and convert it to jframe or something similar so that i can have my own frame design (Background)?

I'm having difficulty adding Chess Pieces to my Java Program. The Problem being that I'm unable to figure out how to add a chess piece to their corresponding location on a chess board. I've tried several things but nothing seems to work. This is what I have so far.
public class ChessGUI extends JPanel {
public int squareSize = 64;
public int x = 0;
public int y = 0;
private final JPanel GUI = new JPanel();
private JButton[][] chessBoardTiles = new JButton[8][8];

So far I've just been testing stuff...

I developed some servlet to get unicode parameters via post request. It worked perfectly fine since I set the encoding as below:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
HttpSession session = request.getSession(false);
response.setCharacterEncoding("UTF-8");
response.setContentType("text/html");
request.setCharacterEncoding("UTF-8");
String fileContent = request.getParameter("fileContent");
}
Now that I have set up my dev environment on a new machine with new eclipse, it does not work.
It displays Ï instead of π.
I've already tried adding URIEncoding="UTF-8" to server.xml which did not work since it only affect get not post. I figured out how to get the parameter with correct encoding on the new system:
String[] parameters = URLDecoder.decode(request.getQueryString(), "UTF-8").split("&");
But I cannot believe that this is the solution because then what's the point of having request.getParameter. I already know that:
String sss = new String(fileContent.getBytes(),"UTF-8");
would not work.

I must write a method that accepts a string and returns an int. The method should sum the unicode values of each character, so the string "ABC" should return 198. Also the only string class methods I'm aloud to use are length, charAt, and substring. I just don't know how the get the Unicode value.

I am learning about Lambdas and am having a little difficulty in a conversion. I need to introduce a List into which the array supplied by the values method of the Field class is copied, using the asList method of the class Arrays. Then I need to convert the for loop with a forEach internal loop using a lambda expression as its parameter. The body of the lambda expression will be the code that is the present body of the for loop. I believe I have the List syntax correct ( List<String> list = Arrays.asList(data); ), but I am having a hard time on figuring out what to do with the for loop, or even where to start with it.
public AreaData(String... data) {
List<String> list = Arrays.asList(data);
/* Assert to check that the data is of the expected number of items. */
assert data.length == Field.values().length : "Incorrect number of fields";
for( Field field : Field.values() )

I created a word object representing a specified string under my public class word method such as
Word w = new Word("Blue");
now I am required to return a hashcode for this word, which is an integer based on the words instance data under the method called
public Word(String w);
{
}
I am not sure how to convert the string into an int so I would be able to return a hashcode.

I'm very new to Java and need to write a program where the user inputs any number from -999 to 999 and it inputs it in words. For ex -24 entered would print negative twenty four or 800 entered would be eight hundred. I need to have at least 2 methods that need to be returned to the main method. When i compile, it says that cannot convert from void to java.lang.string for all the word = ... in my case statements.
import java.util.Scanner;
public class NumToText {
public static void main (String args[]){
Scanner input = new Scanner (System.in) ;
System.out.println ("Enter number.");
int number = input.nextInt ();

//Students Full Name
firstName = JOptionPane.showInputDialog("Enter student " +
"first name.");
lastName = JOptionPane.showInputDialog("Enter student " +
"last name.");
// Get test grade (numbers)
[b]test1 = JOptionPane.showInputDialog("Enter test1 grade")[/b];
The line in bold is where that error comes up. I know it something simple but I can't remember. I declared both firstName and lastName as Strings and then the test1 I declared as double. I had a similar error in a previous assignment where I had a integer(age) input and then i had an output statement asking for a name all I needed to do was put keyboard.nextLine(); after my age input and I was fine.

I have to make a programm where the user gives you the bank sorting code and the account number and you give him the IBAN. That was so far no problem and I was done within minutes except of one thing that I simply can't figure out even though im trying since weeks. At some point I have to convert a string to integer. My research told me its with parseInt() and I dont get a syntax error when I compile my programm (using BlueJ). But when executing the programm stops and gives me some weird bug message. Here is code and bug message:
Java Code:
public class IBAN {
public IBAN(String Bankleitzahl, String Kontonummer) {
Bankleitzahl=Bankleitzahl.replace(" ",""); // Die Leerzeichen werden entfernt
int Anzahl=Bankleitzahl.length(); // Auf der Variabel Anzahl wird die Anzahl der Zeichen von der Bankleitzahl gespeichert

Write a program that will provide temperature conversions between degrees Fahrenheit and degrees Celsius. Provide a method that will take an argument representing a temperature in Fahrenheit degrees and return the equivalent temperature in degrees Celsius. Also provide a method that will take an argument representing a temperature in degrees Celsius and return the equivalent temperature in degrees Fahrenheit. Conversion formulas are as follows: F = 9./5. * C + 32, C = 5./9. * ( F - 32 ), where F = Fahrenheit temperature and C = Celsius temperature. You must prompt for input using the Input class methods that are provided as a download for this unit.
I have two questions, 1st is why won't I get an output from my program when I run it? 2nd is how do I prompt for input using the Input class methods downloaded? The downloaded files are in .class form, and won't show any output when I run them.My code is:
import java.util.*;
public class temp
{
public static void main ( String [] args )
{
Scanner in = new Scanner(System.in);
