View RepliesI am having a small JavaFX program where I try to set a value to TextField. Below is the part of FXML file and highlighted is the Textfield ....
fxml file
<AnchorPane minHeight="0.0" minWidth="0.0" prefHeight="185.0" prefWidth="598.0">
<children>
<TextField fx:id="actiontarget" editable="true" layoutX="146.0" layoutY="73.0" prefWidth="198.0" text="" />
[Code] ...
I want to display a string value to that text field.
So, I am using that fxid (actiontarget)
But actiontarget.setText (pathofFile) is not working .
Nothing displays and no value sets for the Text field.
How can I set value in that text field through above code.

I have tried different sizes for the 'TextField' but when I change the size, the position changes instead of the size itself.
I've done a lot of hardwork for this assignment but I don't know what's why the second textfield which is for output is blank.
All I want is to get the input from user in textfield a and display it in textfield b in lower case.
public void KeyPressed (KeyEvent ke) {
String letter2="";
if(ke.getKeyCode()==KeyEvent.VK_A)
{
letter2=letter2+"a";
btextfield.setText(letter2);

I am currently working on a small java programm. I use netbeans for it. And obviously I am new to java.
Basically its a calculator that change the input value into another value: like 10 € into whatever $ and same with Inch and Centimeters.
Therefore I need a second jDialog Form where i can change the factors for the calculator and start the calculator again.
Here is my problem: I can open the second Dialog but if I want to change the factor it doesn't change the value in the variable and the second calculator frame is with the old factors. It seems the double variable isn't working globally
I will add the files later when i find out how?
I am trying to change an input String to an array of characters, but it only stores the word before the space into the array. Here is the code:
Scanner scanner = new Scanner(System.in);
System.out.println(" Enter text: " );
String text = scanner.next();
char[] characterArray = text.toCharArray(); // convert string to array of characters
String char = "";
for( i = 0; i < characterArray.length; i++) {
char = char + characterArray[i]
} System.out.println(char);
Just typing hello gives me hello, but when I type hello world it does not type in the word "world".I am trying to change an input String to an array of characters, but it only stores the word before the space into the array.Here is the code:

I have to do a small program about parking. In the 2-d array (parking lot), contains different kinds of cars, the user have to :
1)enter which car he wanna move,
2)what direction (w,a,s,d) and after that,
3) how many moves( not out of bound) he wants to make, and finally
4) we print out the new parking lot for his next move
And i am stuck at how to move the car to corresponding position and then prompt user for the next move?
For example:
I want to move A to the right by 1 (d)
擷取.PNG
print result:
擷取1.PNG
How do I do that? The code that i have right now
public class CarParkGame {
public static void main( String [] args) {
String carPark[][] = new String [6][6] ;
carPark[0] = new String[] {"A","A","A","0","0","0"};
carPark[1] = new String[] {"b","0","0","0","0","c"};
carPark[2] = new String[] {"b","X","X","0","0","c","<exit>"};

I'm quite new to java programming, but eager to learn. I was wondering how to change actual java code, using user input. For example:
Java Code: int x = 0;
// Start the program and enter 3
// Now the code is
int x = 3 mh_sh_highlight_all('java');
I'd like to change the text on the two buttons which I have in my Dialog Box, how should I do this?
Also, when I click the X Button in the top right of the Dialog Box, nothing happens, and the program only stops when I end it in jGrasp. How do I make this button close the program when clicked on?

I select the first row the value is 0
I select the second the value is still 0

I have 2 textfield that take username and password, on the database thete is a user table
id username password name surname
1 test test test test
people put username and password to the textfield like test test and they logon,but when they write username = TESt and password = teST they can logon too,there is no TESt user on the database or teST password, is the textfield making lowercase all text. or pst.setString(1, username.getText()); is this code changing the text?
I am working on a keypad for a phone app for school. I cannot get the numbers from the keys to show up in the textField. I have made multiple tweaks, but think maybe my case statement is the problem?We did a calculator application in the class, so I have based my code off of that. Although the telephone keypad seemed much simpler to code, I can't seem to get the numbers to show up.
public void actionPerformed(ActionEvent e) {
//test for button clicks
foundKey = false;
//search for clicked key
for (int i=0; i<keys.length && !foundKey; i++)

What would be the simplest way of creating a Dialog that can add TextField dynamically based on whether a radio button option from the dialog box is selected. I thought of JOptionPane.showMessageDialog and adding a JComponent though I would not be able to add a TextField on the fly and I would not be able to add ActionListeners. The dialog would initially contain some radio buttons, labels and textfields.
