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;
}
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)?
import java.io.*; public class Main { /** * @param args the command line arguments */ public static void main(String[] args) throws IOException { /// instantiate data input stream DataInputStream din = new DataInputStream (System.in); // Ask user to enter a message

I want to show the unicode value of input character but it does not work
"Write a program that takes a word and displays the sum of the numbers comprising its character's Unicode values. "Here is my code:
/** * Description: Prints the word "Sunny" as well as printing the */ public class Assign1{ public static void main(String[] args){ String sun=new String("Sunny"); System.out.println(sun); // Prints Sunny //sets values as strings
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];
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:
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 have a jsp page which contains two text areas inside two separate form tags. i want to submit unicode date in one textarea and display it in another. But nothing is working for me. i have to show basically all Indian Languages and english as well. here is the code of it
I am making a program which accepts two user inputs one being a letter either upper or lower case and the other being a number. the out come should be some thing like this:
G GG GGG GGGG GGGGG
This is assuming the user inputted 'G' and '5'.
here is the code i have so far:
package week10; import java.util.Scanner; public class integer { public static void main(String args[]) { Scanner user_input = new Scanner( System.in );
[Code] ....
The problem i am having is that i cant get the number that is inputted to be accepted as a variable to be used for the program.
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'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);
I am using netbeans scenebuilder and I am a little confused on how I would convert my state capitals java code to a javaFX app.
public class StateCapitals { Scanner in; public static void main(String[] args) { readData(); } public static void readData() { // Location of file to read File file = new File("statecapitals.txt");
