    Default Java project

    A text field, in which a row of numbers can be written. Next to it a button, with the help of which the written information can be saved as a file //to show where the file will be saved and its name//
    Another field for searching in the file. And the found result, if it coincides, to be saved in new file. Example:
    We write the row 12982732937 // save it in file.
    We are searching 7, if there is coincidence, we save the result in another file. If there is no message

    Thanks you.

    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..
    Please use [highlight=Java] code [/highlight] tags when posting your code.

    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).

    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.
