Thread: Java project

Hello monika88a.

Welcome to the Java Programming Forums.

Have you started to code any of this yet? You will need to use Java Swing for the text field and button..

Code is what you right to tell the computer what to do. It looks something like this:

public static void main(String[] args)
{
     System.out.println("Hello world!");
}

Obviously, your Java code will look different because it must fulfill different functionality. I would recommend reading Learning the Java Language by Sun (the makers of Java, err at least the current maintainers of it). You may also want to take a look at How to Use Text Fields (also written by Sun).

yes here is code forim text field :

void jTextFiled1_actionPerformed(ActionEven e) {
 
 
}

and save button:

void save_actionPerformed(ActionEven e) {
 
 
}

I dont know hot to connect save button to save text in texfiled... please help from first part of condition

What I would do is create instance variables for a JButton and JTextField in your main application GUI class. Then, add your application as the ActionListener for the JButton. Everytime the JButton is clicked, it will send an ActionEvent to your actionPerformed method (you must implement this method

public class GUI implements ActionListener
{
     // a simple class that implements an ActionListener
     public void actionPerformed(ActionEvent e)
     {
          // any code you want whenever this method is triggered
          if (e.getAction.equals("Add"))
          {
               // received an action labeled "Add". Stuff to handle this action is here
          }
     }
}

By default, JButton sends out the action that matches it's displaying text, but this can be changed using the setActionCommand(String action) method. To add your program as an action listener to a JButton (or most other swing components):

someJButton.add(someActionListener);

Practically, this should be somewhere inside of your GUI initializer method, so it can look something like this:

someJButton.add(this);

Because you don't need to keep track of the text everytime it changes and only when the button is pressed, you can poll the text only when the action event is fired. To get the text in the JTextField:

someJTextField.getText();

hopefully that helps you with the swing portion of your program.
