All the entries in the table are of type String.However, the String content for the “Head4” column can be very larger and displaying this makes the table very large.As an alternative, is there a way to provide a button for the “Head4” for each row and when the user selects the button on that row, the corresponding “Head4” column contents is displayed in a pop up dialog box ? I am using Primefaces 5.0.
I have a Jtable which shows contents on each row. but the row contents which are bigger than the width of the column gets shown as "BlahBlah.." (basically getting showed up as .. in the end)
User has to manually increase the width of the column to see those extra contents.For e.g if the row contents are ABCDEFGHI and the widht of the column for that row is sufficient enough to show only ABCDEF of that, then it will show up as something like "ABCD.."Now my requirement is to show the complete contents over to next column on the same row.
Note: I could simply add the code to show the widht of the column to adjust according to largest row content for that column . But unfortunately this is not what is required.
I've setup an array that I would like to analyze by adding up the contents of each column, however, the out of bounds exception pops up when I try to execute the program. I know the book usually expresses this operation the other way around, where the row is the argument of the first for statement, but I've set my array up where I need to add each row before moving to the next column.
vowelCounter is a 5x3 array.
// Display the line which had the most number of vowels
public static int maxVowelSentence() { int max = 0, sum = 0; int sentence = 1; for (int row = 0; row < vowelCounter.length; row++) { max = vowelCounter[row][0];
I want to read this csv file and store contents on column basis; as date (single array) for all dates. open, high, low and close and be able to manipulate individual elements of the array such as Sum += close[i];
public void pratice() throws Exception { // Create a File instance BufferedReader br=new BufferedReader(new FileReader("gtk.csv")); content = new String[1000]; while(content !=null) { content[++count] = br.readLine();
How do you make it so that you can select 2 buttons in a radio button group? for example: If I have 7 radio buttons, and I want to be able to select 2 of the 7 instead of 1.
I want to develop simple example in which I can select TreeView Nodes with Buttons(in some cases clicking on image and etc). I created this simple sample:
I'm making an application that will allow users to view several displays simultaneously. I'm trying to make it so that the user should be able to select one of the items from a list then hit a radio button add them to the display. And there will be a second button to remove them from the display. Oh and there will always be alteast one display.
I'm trying to figure out how to display a JPANEL and be able to select a file to review it, but off the bat I having problmes figuring out the first steps I have some code how to start properly or what i need to make this work,
import java.io.*; import javax.swing.*; public class checkValue { //create a Dialog box to locate the site file public static String propertiesFilePath; public static JButton siteBrowse = new JButton("Browse"); public static void main(String[] args){
The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.
I have to write a program that calculates the average temperature for a month using parallel arrays (it is mandatory to use a parallel array). I'm new to Java (I'm more familiar with C++) so I get confused with the use of methods. I know how to compute the averages already, I just setting up the parallel arrays. This is what I have so far:
Java Code:
import javax.swing.*; import java.util.Scanner; public class Temperature { public static void main(String[] args) { String[] day = {"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"}; int[] temp = new int [7];
[Code] .....
For now I just want to show the contents in my array before I start computing averages.
Create a class that allows the user to select a file and output the contents of the file to the console. Recommend using a text file to display, java files are text files. You may want to put this code in a method to allow you to complete the remainder of this assignment without overwriting your code.
- You should ask the user to enter the full path to your file to make certain you are processing the correct file.
- Modify your code/add a method to display the contents of the file in reverse order. You do not need to reverse the characters on each line but simply output the lines of the file in reverse order.
Hint: read the content of the file into an ArrayList and then traverse the ArrayList.
this is what i go so far.
package classActivity;
import java.io.File; import java.io.FileNotFoundException; import java.io.PrintWriter; import java.util.ArrayList; import java.util.Collections; import java.util.Scanner; public class Select { public static String enterFilePath()
I'm developing Chat application GUI using SWING. My GUI has two JtestAreas one for displaying message that i was sent, and another for displaying replay coming from server. I was used Thread.sleep(1000) after message sent . Due to that, AWT-EventQueue-0 thread stops to display send message in first JtextArea and waits until it get response from server. After got response from server, in one shot, My GUI displays both JtetAreas Content.
But, I need to display send Message and Response Message in two different shots. I know the reason why it displays in one shot.
I am currently working on a project where I have a dataTable, containing some of the information for a specific database table, with commandLinks at the side which I need to bring me to a new page(another jsf file that I have to display the relevant information there) and display only the row of data selected. I've been racking my brain about this and have been unable to figure out a way to do it.
I have been trying to get my radio buttons to display text when they are selected in a textbox but for some reason no matter what i try it wont display. Here is my code i have removed my attempt to get the action listener working.
package listVsSet.Desktop.copy; import java.awt.BorderLayout; public class ListVsSetGui extends JFrame { private JPanel contentPane; private JMenuBar menuBar; private JMenuItem mntnListVsSet;
I am writing code for a form in which i want to display data by selecting radiobutton.The code is working for single radiobutton but it not work when i select the other radiobutton.
Capture.PNG1.jpg
the code is given below:]
private void jRadioButton1ActionPerformed(java.awt.event.Action Event evt) { // TODO add your handling code here: int LIMIT = Integer.parseInt(jTextField2.getText()); int ULIMIT = Integer.parseInt(jTextField3.getText()); { DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
I'm trying to make it to where each button is supposed to display the country's flag and a description. As of right now, I've hit a roadblock and haven't been able to get past it. As of right now, without the errors in the setDisplay method where setTitle and the other two are undefined for that type, I get each country's name listed as a radio button.
However, I haven't been able to get anything else to display.
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Flags extends JFrame{ private String[] flagTitles= {"Canada", "China", "Denmark", "France", "Germany", "India", "Norway", "United Kingdom", "United States of America"}; private ImageIcon[] flagImage= {
I have jFrame where I have to display data from database on button click. There are 4 buttons, first to display the first record in database, last to display the last record in database, next to display the next record and previous to display the previous record. I have done first and last record but what should I do to display the next and previous record.
I am trying to write a specific byte sequence to a specific memory location on a removable storage drive. Does Java allow me a way to do this? I know the dangers in accessing memory, but the memory location of the data that will be written will never change.
- from the main class will arrive three variable (String name_used, int level_choose, int level_result)
I have a .txt file with this kind of formatting:
mario 1 1 0 1 0 1 carlo 0 0 0 1 1 0 ...
Where I use 1 and 0 in the main for write if the level (you see that the numbers are always sixr? are egual to six level existing) BEFORE is done correct or wrong
- when in the main a user make a level a feedback coming back from the class level saying if the user made the count correctly or wrong. and i wanna replace the value (1 or 0) in the txt file with the new level result.
So i have all what i need as parameters i think.
name_used to look for the correct line in .txt file with .indexOf level_choosed to go throught the correct index of that line level_result (1 or 2) to be replaced with the existing one
Java Code:
public void salvaRisultati(String name_used, int level_choosed, int result_of_level) throws FileNotFoundException{ } } mh_sh_highlight_all('java');
I have some problem to understand the way to make this:
In my main class a user can save his name in a txt file (and the system initially will add 6 value equals to 0) than he can choose between 6 level and make it.
example of .txt file data:
mario 0 0 0 0 0 0 carl 0 0 0 0 0 0
AT THIS MOMENT i just made other class and they work, is this new one that is hard for me. I'm trying to make a class that:
1- (first method called verificaRisultati) take name_used and level_choosed from the main and go to check in the .txt file if that level before was done right(1) or wrong(0)
and return something like "before you made this level properly" or "before you made this level incorrectly" AND THEN let the user start with the level.
2- (second method called salvaRisultati) at the end of the level i wanna pass the result (correct/incorrect) to another method of this class that will save the value (1 or 0) associated to the user in the right position.
This is the class that i'm writing:
Java Code:
import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; public class ResultUsers {
[Code] ....
I really need some hint and some code example because I'm stuck. How I can take exactly the line with the user name? How I can correctly split the line in an array and then read/modify the value for that level?
Write a method that returns the sum of all the elements in a specified column ina matrix using the following header:
Public static double sumColumn(double[][] m, int columnIndex)
Write a test program that reads a 3 by 4 matrix and displays the sum of each column.
