Exchange variable between two jFrames

Exchange variable between two jFrames - java

I have 3 java files.
DBConn - This Class conencts to the database and execute query.
UserLogin - This jFrame will take username and password and compare with "users" table
if it matches it will display "Login Successfull" in LibSysMain java file
LibSysMain - This is the main file which shows the menu.
This is the jFrame which is displayed first when application is run.
The problem is I am not able to set the "Login Successful" message in LibSysMain.
My Database is MS Access. Table name is "users". Field is "username" and "password". Both of them are of string type.
A help would be highly apprecited.
I am new in Java. I am using NetBeans 6.9.1.
Here is the list:
DBConn:

I have a couple of suggestions:
For one, don't compare Strings with == as you do here if (ul.getStatus() == "pass") as this checks to see if two variables refer to the same String object (which you don't care about) but rather use either the equals or the equalsIgnoreCase method which checks to see if the two Strings contain the same String data (which you do care about). e.g., if (ul.getStatus().equalsIgnoreCase("pass"))
Be sure to do all of your database queries and whatnot in a thread background to the GUI's thread, the EDT such as can be achieved by using a SwingWorker object. This article will tell you what I said but will give you the details: Concurrency in Swing.
Consider using a single JFrame and modal dialogs to act as dialog windows to the main app. This can be achieved by using JOptionPanes or modal JDialogs, in particular for your UserLogin window.
For this reason, I like to gear my GUI's towards creating JPanels rather than top level windows such as JFrames. This way I can place my GUI/JPanel into any type of window I desire depending on the situation be it a JFrame, a JApplet, a JDialog, a JOptionPane, or even nested into another JPanel. This gives you an amazing amount of flexibilty.

Radio Button In Java

I just want to ask if I can change the text in radio button.
For example:
here in the picture if I put a number, it will show the number factors at the radio button. ( the factor 1 will just show in Jlabel and the rest of the factor will show at the Radio button) the problem part at the private void checkbtnActionPerformed(java.awt.event.ActionEvent evt) I already tried to use .setText() but I think this will not work for radio button or button group. Is there another way to do that

Should I use substring to avoid a certain string in java database or is there another way to bypass it?

I am building a product database and when I'm using the update database function my program crashes.
The issue is one string the program itself throws in.
I retrieve the data from the database text file and because I'm using numberformat.getCurrencyInstance and it throws in a dollar sign. So I threw in an exception String price = updatePriceTextField.getText().substring(1); so it would bypass the dollar sign in the beginning of the text field and send the information back to the textfile and save.
Now it brought up my current problem which is: when I enter a number bigger than 999 and I get to thousands, it brings in a comma: example: $3000.00 is now $3,000.00 and when i try to send that information back to the database it throws in an error and crashes.
Now I know I could just simply add in another substring to avoid, and solve the problem like that, but what if the price of the object lets say is: $300000000.00 the the program throws in 2 commas $300,000,000.00 and would crash again. So what sort of exception or command should I throw in to bypass these commas except substring.
Sorry for the long post, but I tried to explain the issue as well as I could.

Use a JFormattedTextField instead, this way you just use getValue and it will return you the unformatted value for the field.

Having trouble converting textfield to integer and more

a little information on my assignment:
Based on the Person class previously defined, design your own Java application that displays a form for a user to enter their name, year_of_birth and employment status. The provided data will be used to instantiate a Person object. The form should also include a JButton and a JTextField. When the user clicks on the JButton the application should display “Welcome [name]! You are [age] old. Time has been kind to you.”, where [name] and [age] are the current values of the name and age attributes of the Person object.
I am a little new to creating GUI's. I have used the jFrame design that allows me to create the design of the GUI. I am having trouble using that form to display the results. Specifically, having the button display the results, having there name stored in a variable once they type it in, and brining up a dialog box once the button is clicked with the message.

Any help would be greatly appreciated. I am already past the due date and very confused on how coding for GUI's go.

There is whole lot of unnecessary code you have. you need to clean it up for example you have 3 dialog instances. you do not need them. coming to your question you need to write implementation like:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// This will display message
JOptionPane.showMessageDialog(this, "Welcome" + name.getText() + " ! You are " + getAge(Integer.parseInt(year_of_berth.getText())) + " old. Time has been kind to you.");
// here you need to write code to populate your Person Object.
}
Hope this helps

You don't need a event for every textField. This:
name.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
nameActionPerformed(evt);
}
});
year_of_birth.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
year_of_birthActionPerformed(evt);
}
});
I wipe this fragment of code.
You only need an event when the user click the button, therefore this event what you'll need.
Instead of the methods nameActionPerformed() and year_of_birthActionPerformed(), I would create a getName() and getYearOfBirth() methods.
private String getName(){
return name.getText();
}
private int getYearOfBirth(){
return Integer.parseInt(year_of_birth.getText());
}
Then, in the method of button event:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
String name = getName();
int year = getYearOfBirth();
System.out.println("Welcome" + name + " ! You are " + getAge(year) + " old. Time has been kind to you.");
}

Java, select text Exactly in JEditorPane

I'm using jEditorPane to act kinda as some editor, the one who asked for this of me, also needed a find replace search... so I wanted to let him select in find and then do replace on need.
so I provide this simple code:
private void jButton5ActionPerformed(java.awt.event.ActionEvent evt) {
int start = (jEditorPane1.getSelectionStart()>jEditorPane1.getSelectionEnd())?jEditorPane1.getSelectionEnd():jEditorPane1.getSelectionStart();
int max = (start>jEditorPane1.getSelectionStart())?start:jEditorPane1.getSelectionStart();
String searchWord = jTextField3.getText();
int searchIndex = jEditorPane1.getText().indexOf(searchWord, max);
if(searchIndex != -1){
jEditorPane1.select(searchIndex, searchIndex+searchWord.length());
}
else{
jEditorPane1.setSelectionStart(-1);
jEditorPane1.setSelectionEnd(-1);
}
}
fortunatelly the application return good indexes, but unfortunatelly on view windows I see no selection.
I'm also new to java, please help
PS. buttons action are provided by netbeans itself

The selection of a text component is only displayed when the text component has focus. When you click on the button it gains focus so you don't see the text selection. You could make the button non-focusable or you can add the following to the bottom of your actionPerformed() method:
jTextPane1.requestFocusInWindow();
Also, don't use the getText() method. This will cause problems with offsets.
int searchIndex = jTextPane1.getText().indexOf(searchWord, startFrom);
See Text and New Lines for more information and a solution. The basics of this link is to use:
int length = textPane.getDocument().getLength();
String text = textPane.getDocument().getText(0, length);
The above will only return "\n" as the EOL string so the offsets will match when you do a search and then select the text.
Edit:
I generally use code like the following:
int startFrom = jTextPane1.getCaretPosition();

I would seriously advise you to take a time out, and refactor all of your code. Igonoring that in the class new8, in method decode replace this code:
new vpsfame().ac.setText(t[1].substring(1,2));
System.out.println("Lattitude: "+t[3]);
System.out.println("Direction of Lattitude: "+t[4]);
new vpsfame().ab.setText(t[3].concat(t[4]));
System.out.println("Longitude: "+t[5]);
System.out.println("Direction of Longitude: "+t[6]);
new vpsfame().bc.setText(t[5].concat(t[6]));
System.out.println("Speed over Ground: "+t[7]);
new vpsfame().cd.setText(t[7]);
With this:
//use one object, dont just create new frames
vpsfame myFrame = new vpsfame();
myFrame.ac.setText(t[1].substring(1,2));
System.out.println("Lattitude: "+t[3]);
System.out.println("Direction of Lattitude: "+t[4]);
myFrame.ab.setText(t[3].concat(t[4]));
System.out.println("Longitude: "+t[5]);
System.out.println("Direction of Longitude: "+t[6]);
myFrame.bc.setText(t[5].concat(t[6]));
System.out.println("Speed over Ground: "+t[7]);
myFrame.cd.setText(t[7]);
//Also set the frame to visible, so it can be displayed once you've done all this work.
myFrame.setVisible(true);
The problem is that:
Firstly, you are creating multiple vpsframe objects where you should only have one. It makes no sense to create 5 frames where each will have 4 empty fields. Create one object and initialise all it's fields rather than using 5 diffrent objects.
You are not tracking the objects you are creating, the garbage collector will just get rid of the, so create one object, assign it to a variable and use that.
Set the vpsfame object to visible, otherwise you will never see it.
Your code also needs refactoring, you should be using the camelCase naming convention, and classes should always begin with Capital letters.
