how to print text from a JtextField by clicking a JButton

how to print text from a JtextField by clicking a JButton - java

I'm creating a little program for my self to learn Java now I did make a GUI with 12 JTextFields and now I want to use the text that's in the text fields in another class where I print them out.
When I press the button class print is successful, summand I get the last System.out.println("Test if class is triggerd") in my console but I don't get the JTextFields output in the console

}

This is happening because you create on the print class a new Object of frame1 so the variables by default are null. You can add on the Print method a list parameter that stores all the Strings in that list.
public void Print(List<String> slots) {
System.out.println(slots.get(0));
System.out.println(slots.get(1));
System.out.println(slots.get(2));
System.out.println(slots.get(3));
System.out.println(slots.get(4));
System.out.println(slots.get(5));
System.out.println(slots.get(6));
System.out.println(slots.get(7));
System.out.println(slots.get(8));
System.out.println(slots.get(9));
System.out.println(slots.get(10));
System.out.println(slots.get(11));
}
and redefine before the method call all the variables and store them in the list.
You can learn some things about Java's lists here
If you are struggling finding the code I made it for you
slot1 = txtSlot.getText();
slot2 = textField_1.getText();
slot3 = textField_2.getText();;
slot4 = textField_3.getText();;
slot5 = textField_4.getText();;
slot6 = textField_5.getText();;
slot7 = textField_6.getText();;
slot8 = textField_7.getText();;
slot9 = textField_8.getText();;
output = textField_9.getText();
List<String> slots = new ArrayList<String>();
slots.add(slot1);
slots.add(slot2);
slots.add(slot3);
slots.add(slot4);
slots.add(slot5);
slots.add(slot6);
slots.add(slot7);
slots.add(slot8);
slots.add(slot9);
slots.add(output);
slots.add(output_count);
slots.add(file_num);
output_count = textField_11.getText();
file_num = textField_10.getText();
TestLabel.setText(textField_10.getText());
print name = new print();
name.Print(slots);
and Print class:
public void Print(List<String> slots) {
System.out.println(slots.get(0));
System.out.println(slots.get(1));
System.out.println(slots.get(2));
System.out.println(slots.get(3));
System.out.println(slots.get(4));
System.out.println(slots.get(5));
System.out.println(slots.get(6));
System.out.println(slots.get(7));
System.out.println(slots.get(8));
System.out.println(slots.get(9));
System.out.println(slots.get(10));
System.out.println(slots.get(11));
System.out.println("Test if class is triggerd");

Jcombobox not selecting item

Im trying to insert the Jcombobox value into my sqlite database but whenever I run the program, it only inserts '9' in to my database. Please advise. I am trying to import the integer that the user picks into my sqlite database. For some reason, even with the action listener, the default value, 9, is still being inputed into the table and im not sure why. Here is the full code, not including the connection and the Jtable.

It inserts 9 to your database because the selected item is always 9, and this because you add it first to your combobox. In order to insert the selected value, you will have to use an ActionListener. Then you can take user's selection and do whatever you want.
An example of its usage:
import java.awt.FlowLayout;
import java.io.FileNotFoundException;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
public class ComboBox extends JFrame {
public ComboBox() {
setDefaultCloseOperation(EXIT_ON_CLOSE);
setSize(300, 300);
setLocationRelativeTo(null);
getContentPane().setLayout(new FlowLayout());
Integer[] numbers = { 4, 5, 8, 123, 42, 634 };
JComboBox<Integer> comboBox = new JComboBox<>(numbers);
comboBox.setSelectedItem(42); // The initial selection is 42.
comboBox.addActionListener(e -> {
int selectedNumber = (int) comboBox.getSelectedItem();
System.out.println("Selected number: " + selectedNumber);
// Do whatever with selected number
});
add(comboBox);
}
public static void main(String[] args) throws FileNotFoundException {
SwingUtilities.invokeLater(() -> new ComboBox().setVisible(true));
}
}

Graphical User Interface and Main Method needs sorting

Im trying to sort my GUI so it will be able to use the methods from the other classes
in the JProject i also want to call it from the main.
The action listeners i had just learnt today so i need feedback on what to do there as well.
Any Ideas??
It would be a great help to get some insight on this!
(I am new to stack so my code posted in the explanation and in the actual script idk
why).

Enable labels and textfields based on the selected item in the combo box of another class

I have two separate classes: SubDimensions.java and Subtraction.java.
I wanted to enable some components in the Subtraction class based on the selected item in the combo box of the SubDimensions class.

You are not using the parameter enabled in Subtraction.java, change to:
public void x3Visibility (boolean enabled){
lblX3.setEnabled(enabled);
textFieldx3.setEnabled(enabled);
lblY3.setEnabled(enabled);
textFieldy3.setEnabled(enabled);
}
Edit: looks like you lack the fundamental understanding of object-oriented programming (OOP).
When you call
Subtraction subtraction = new Subtraction();
subtraction.Subtraction();
You created another instance of Subtraction called window:
public static void Subtraction() {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Subtraction window = new Subtraction();
window.frmSubtraction.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
substraction is not visible while window is. But window is not in the scope of actionPerformed and hence you cannot access it. For now, you can change the actionPerformed to below to resolve your issue temporarily. But I strongly recommend you to: 1) revisit the concept of OOP 2) try to use arrays or collections for your labels and textfields instead of hardcoding them one by one
public void actionPerformed(ActionEvent e) {
Subtraction subtraction = new Subtraction();
subtraction.frmSubtraction.setVisible(true);
frmSubDimensions.setVisible(false);
switch(comboBoxA.getSelectedItem().toString()){
case "3x1":{
subtraction.x3Visibility(true);
break;}
/*case "4x1":
lblX4.setEnabled(true);
break;*/
default:{
subtraction.x3Visibility(false);
break;}
}
}

JApplet issue stating class not found and class not found exception

I am having an issue that is giving me an error message and a blank applet is appearing. The error message says load:class Myapp.class not found and java.lang.ClassNotFoundException and then a list of lines saying # and then some other jargon.
If I run try to run the program as a Jcreator applet like I expected I get the prior stated error and if I run it in an application it just gives me the main method error.

Write the itemListener with a captial letter like this
public class Myapp extends JApplet implements ItemListener{
and import all this packages:
import java.awt.Color;
import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.JApplet;
import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JInternalFrame;
import javax.swing.JLabel;
import javax.swing.JTextArea;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;

generating the correct xml from jaxb

I am generating a xml by taking input from the user in the swing form , now I want that xml parameters value should be set as what user enters for example user enter the following values for the following parameters...
route cna="trk"
typ="e_pwap"
ver="96"
sk_cna="ltp6"
sk_typ="55"
sk_ver="26"
prefilterfilename="sjj"
prefiltertype="true"
postfilterfilename=""
postfiltertype=""
xfm=""
gelcatnumbersource="16"
gelcatnumbersink="40"
so the final xml should be generated would be...
<route cna="trk" typ="e_pwap" ver="96" sk_cna="ltp6" sk_typ="55" sk_ver="26" prefilterfilename="sjj" prefiltertype="true" postfilterfilename="" postfiltertype="" xfm="" gelcatnumbersource="16" gelcatnumbersink="40" />
right now it is not happening even if the user enters the value, right now it is printing as ...
<route cna="cnavalue" typ="typ" ver="ver" sk_cna="sk_cna" sk_typ="sk_typ" sk_ver="sk_ver" prefilterfilename="prefilterfilename" prefiltertype="prefiltertype" postfilterfilename="postfilterfilename" postfiltertype="postfiltertype" gelcatnumbersource="gelcatnumbersource" gelcatnumbersink="gelcatnumbersink"/>
please advise how to correct this. Below is my pojo..

Well, setting the field's value to "cnavalue" will indeed result in the XML to contain an attribute cnavalue="cnavalue".
Route route = new Route();
route.setCna( "cnavalue" );
Use something like
route.setCna( textField_1.getText() );
