This is my code:
JDialog dialog = new JDialog();
dialog.setSize(400, 150);
dialog.setTitle("Input dialog");
dialog.add( new JLabel("simtime(min)") );
dialog.add( new JLabel("interval(sec)") );
dialog.setVisible(true);
The problem is that the two lables replace each other.How to position them where we want?
We are asked to create a JDialog showing our database. I am able to show the database but i can't seem to position the heading panel, table and back button. My back button is also not showing up. Here is part of my code...
import java.awt.Color;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.GridLayout;
import java.sql.*;
import javax.swing.*;

All the samples I found use JOptionPane to return a single value. I am looking to return two values from two Text fields.

System.Exit (0)
but it only close the Dialog box
JFrame frame = new JFrame();
frame.setIcon("aaa.ico");
JDilaog dialog = new JDialg(frame, "dialog" , true);
so the dialog has its owner frame, which is neccessary but i want the dialog has another icon ,or remove the icon on the dialog how may i do ?
Lets say the JDialog opens 5x5. The user is allowed to modify its size to be any size larger than 5x5 but is not allowed to make it smaller. Is there such a property or will this have to be regulated via code?
View Replies View RelatedI have a practice exercise here wherein I will add a JOptionPane to a program. When the close button is clicked, the JOptionPane will appear asking the user to exit the program. If the user clicks "Yes," it'll, of course, close the entire program and not just the JOptionPane, but if the user clicks "No," it will return to the program. Please refer to my code below:
try
{
output = new DataOutputStream(new FileOutputStream("ProjSixExe4.dat"));
}
catch(IOException ex) {
this.dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING))
}
final JOptionPane optionpane = new JOptionPane("Are you sure you want to quit
this program?", JOptionPane.QUESTION_MESSAGE, JOptionPane.YES_NO_OPTION);
this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
The exercise said it must be placed before the EXIT_ON_CLOSE portion.
I have JFrame and when I click a button which is in frame JDialog is opened. Now,how can I refresh JFrame when close JDoalog?

I show a JDialog window and this window has 3 buttons when I press one of them it should close the window, how do I do that?
View Replies View RelatedI have a program that using one JFrame which opens one of two JDialog windows depending on which button is pressed.
How do I assign listeners to the buttons and fields on the JDialog window? I added listeners on the View end, but how do I process them? I tried adding the '..implements ActionListener" class in the main Controller but it does not recognize/hear anything.
With the MigLayout for Swing, I'd like to see the JDialog looking like the standard windows Dialog,where to have the OK and cancel buttons at the lower right corner.
View Replies View RelatedI can't figure out why my code doesn't work. My task is to replace for example ä=>ae, using this method String.charAt(int index). So here is my code:
public class pich {
public static void main(String[] args) {
String text = "Die süße Hündin Leica läuft in die Höhle des fülligen Bären "+
"Iliyan (ein Übergrößenträger), der sie zum Teekränzchen eingeladen hat."+

How do you replace negative zero value with a zero value when Printing results:
I want to remove the minus sign in -0.0000 and instead have 0.0000.
I am Printing coordinates and I do not want to have negative zero.
the coordinates are defined as double.
System.out.format(java.util.Locale.US," %.4f %.4f %.4f %.4f%n"xCur ,yCur,xNext,yNext);
0.0000 1.0000 -0.0000 0.0000
Basically, I am trying to write a method that will take a string, a target, and a replacement (a replacement function like string.replace). I want it to replace all instances of target with replacement EXCEPT for instances that occur within single or double quotes.
Example input / output:
this "Wont" be " replaced, be"
call: replace(theString, "replaced", "narf") and replace(theString, "be", "rafn")
output:
this "Wont" rafn " replaced, be"
I am trying write a program that accept an input and present the input with every 5th character replaced with X (count spaces also).
For example:
input: "hello my name is mario"
outpu: "hellX my Xame Xi maXio"
I only manage to replace specific letters, e.g every "m" letter.
I will like replace this code:
// boucle pour les fractions aleatoires
for (i=0; i<2; i++) {
// Creation des fractions aleatoires
Frac first = new Frac(r,5);
Frac second = new Frac(r,5);

But when I use a switch case I do not have the same result as my four loops.
I have a 2D arraylist, named as adjLists, which contains arraylists, containing values like these. Each two values are a "pair" and each third is a "flag" for the pair.
[278, 106, 0, 397, 36, 0, 59, 208, 0, 366, 221, 0]
[366, 221, 0, 397, 36, 0, 132, 390, 0, 278, 106, 0, 295, 0, 0]
I use code above to search for specified value pairs in these lists. vertexnum is the number of "sub arraylists" in adjLists.
for (int l = 0; l < vertexnum; l++) {
if (adjLists.get(l).get(0) == p.x && adjLists.get(l).get(1) == p.y) {
for (int h = 0; h < adjLists.get(l).size(); h += 3) {
for (int g = 0; g < vertexnum; g++) {
if ((vertexSprite[g].getX() + vertexSprite[g].getWidth() / 2) == adjLists.get(l).get(h)
[Code] ....
This code is to search exact values and replace their flag in every occurences. It can not find all the occurences of the values/pair in the lists, it replaces flag value only a few time. Value of score should be incremented with plus 1 after each found occurence, but this code increments it more than the number of matches.

I'm trying to figure out the correct way to replace number into letter. In this case, I need two steps.
First, convert letter to number. Second, restore number to word.
Words list: a = 1, b = 2, f = 6 and k = 11.
I have word: "baafk"
So, for first step, it must be: "211611"
Number "211611" must be converted to "baafk".
But, I failed at second step.
Code I've tried:
public class str_number {
public static void main(String[] args){
String word = "baafk";
String number = word.replace("a", "1").replace("b","2").replace("f","6").replace("k","11");
System.out.println(word);
[Code] .....
Result for converting to number: baafk = 211611 But, result for converting above number to letter: 211611 = bkfk
What do I miss here?

I was reading a book and came across this while loop.
public class Powers {
public static void main (String [] args){
int e;
int result;
for(int i = 0; i < 10; i++){
[Code] .....
This loop presents the following (I'm sure it's not necessary):
2 to the 0 power is 1
2 to the 1 power is 2
2 to the 2 power is 4
2 to the 3 power is 8
2 to the 4 power is 16
2 to the 5 power is 32
2 to the 6 power is 64
2 to the 7 power is 128
2 to the 8 power is 256
2 to the 9 power is 512
I am just having a difficult time understand and grasping this concept. My main issue is result *=2; this is making it very difficult to understand. How is result being replace if it only equals to 1.

My interest in Java leads me to try and print numbers from 1-100. The output should show all numbers from 1-100 and each number that is divisible by by 13 should be replaced with a string "Fuzzy".

for(int i = 0; i < 100; i++)
if(i % 13==0)
System.out.print(i + "fuzzy");
}
