Okay, so I am doing a GUI program and I have trouble retrieving the information that the user will input and call on it from another class so it can be accessed there. Here is the main part of my GUI class, and it starts from the creating of the first textfield:
/**

}
And here's the second class:
public static int software;
public static String name;
public static void Company(){
GUI_project main= new GUI_project();
name=main.getSoftwareName();
if(name.equals("Microsoft")||name.equals("Norton")||name.equals("Oracle")||name.equals("CRM")){
if(name.equals("Microsoft")){
Name.software = 1200000;
}else if(name.equals("Norton")){
Name.software = 3000000;
}else if(name.equals("Oracle")){
Name.software = 1700000;
}else if(name.equals("CRM")){
Name.software = 2300000;
}
}else{
System.out.println("Not a company, GOOD BYE!");
System.exit(0);
}
}
I'm sure that its a silly and stupid mistake, but any help would be great. Once I am able to have these two classes work, the rest should work the same way :)
Try something like the following code.
Test.java
import javax.swing.*;
import java.awt.*;
import javax.swing.event.*;
public class Test
{
JFrame myMainWindow = new JFrame("This is my title");
JPanel firstPanel = new JPanel(null);
JTextField textfield1 = new JTextField();
public void runGUI() {
myMainWindow.setBounds(10, 10, 500, 500);
myMainWindow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
myMainWindow.setLayout(new GridLayout(1,1));
createFirstPanel();
myMainWindow.getContentPane().add(firstPanel);
myMainWindow.setVisible(true);
}
public void createFirstPanel() {
textfield1.setBounds(335,102,90,35);
textfield1.setBackground(new Color(255,255,255));
textfield1.setForeground(new Color(0,0,0));
textfield1.setEnabled(true);
textfield1.setFont(new Font("sansserif",0,12));
textfield1.setVisible(true);
textfield1.getDocument().addDocumentListener(new MyDocumentListener());
firstPanel.add(textfield1);
}
private class MyDocumentListener implements DocumentListener {
public void insertUpdate(DocumentEvent e) {
new Class2(textfield1.getText());
}
public void removeUpdate(DocumentEvent e) {
new Class2(textfield1.getText());
}
public void changedUpdate(DocumentEvent e) {}
}
public static void main(String[] args)
{
Test t = new Test();
t.runGUI();
}
}
Class2.java
public class Class2 {
int software;
public Class2(String s) {
Company(s);
System.out.println(s);
System.out.println(software);
}
public void Company(String s) {
if(s.equals("Microsoft")||s.equals("Norton")||s.equals("Oracle")||s.equals("CRM")){
if(s.equals("Microsoft")) {
software = 1200000;
System.out.println("Matches Microsoft");
} else if(s.equals("Norton")) {
software = 3000000;
System.out.println("Matches Norton");
} else if(s.equals("Oracle")) {
software = 1700000;
System.out.println("Matches Oracle");
} else if(s.equals("CRM")) {
software = 2300000;
System.out.println("Matches CRM");
}
} else {
System.out.println("Not a company, GOOD BYE!");
}
}
}
I changed the KeyAdapter to a Document Listener because the event fires at a better time, which is after the document has changed. Whereas in your version the KeyAdapter was firing events before a letter had been placed in textfield1.
Edit
If you want it to check at the end. Remove the Document Listener and just have the following code in Test.java
import javax.swing.; import java.awt.; import javax.swing.event.; import java.awt.event.;
public class Test
{
JFrame myMainWindow = new JFrame("This is my title");
JPanel firstPanel = new JPanel(null);
JTextField textfield1 = new JTextField();
JButton button1 = new JButton("Check Company");
public void runGUI() {
myMainWindow.setBounds(10, 10, 500, 500);
myMainWindow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
myMainWindow.setLayout(new GridLayout(1,1));
createFirstPanel();
myMainWindow.getContentPane().add(firstPanel);
myMainWindow.setVisible(true);
}
public void createFirstPanel() {
textfield1.setBounds(335,102,90,35);
textfield1.setBackground(new Color(255,255,255));
textfield1.setForeground(new Color(0,0,0));
textfield1.setEnabled(true);
textfield1.setFont(new Font("sansserif",0,12));
textfield1.setVisible(true);
firstPanel.add(textfield1);
button1.setBounds(335,150,150,35);
button1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
new Class2(textfield1.getText());
}
});
firstPanel.add(button1);
}
public static void main(String[] args)
{
Test t = new Test();
t.runGUI();
}
}
