    setLayout(new FlowLayout());

    label = new JLabel("Enter the file path:");
    add(label);

    textfield = new JTextField();
    add(textfield);

    button = new JButton("Open");
    add(button);

    AnyClass ob = new AnyClass();
    button.addActionListener(ob);
}

public class AnyClass implements ActionListener {
    public void actionPerformed(ActionEvent obj) {
        //SecondGUI s =new SecondGUI();
        //s.setVisible(true);
    }
}

public static void main(String[] args) {

What swing component should I use in my second frame to open a text file in it ? If possible, please provide the outline of the code !!

Answer 1

The simplest choice would be a JTextArea.

Another better choice is a JEditorPane.

You can take a look at this text components tutorial for understanding them better and choosing the best you need.
