Question

I need the thing I type in the text field to store in a string so I can use that string in another class.

public void jButton1_actionPerformed(ActionEvent e) {
    String sql = "Select * from clients where username=? and password=?";
    try {
        pst = conn.prepareStatement(sql);
        pst.setString(1, jTextField.getText());

        pst.setString(2, new String(jPasswordField.getPassword())); // /

I need this username I type in the jTextField to store as a string.

Answer 1

You get the text to put it in your PreparedStatement like this:

pst.setString(1, jTextField.getText());

You can use the same method to save it in a String:

String username = jTextField.getText();
