I am trying to set a promt text to a JTextField by using the class FocusLisner but unfortunately I face a problem. The promt text appears only after a press click on the JTextField.



I want the prompt to appear by default when I run the program.



Here is my code:



import java.awt.FlowLayout;

import java.awt.HeadlessException;

import java.awt.event.FocusEvent;

import java.awt.event.FocusListener;



import javax.swing.JButton;

import javax.swing.JFrame;

import javax.swing.JTextField;



/**

 * 

 */

public class PromptText extends JFrame

{

    private JTextField jTextField;





    public static void main( String args )

    {

        new PromptText( );



    }



    public PromptText( ) throws HeadlessException

    {

        super( );

        jTextField = new JTextField( 15);

        addPromptToJTextField( );



        add( jTextField );

        add(new JButton( "Button"));



        setLayout( new FlowLayout( ) );

        setSize( 250, 250 );

        setVisible( true );



    }



    private void addPromptToJTextField( )

    {

        jTextField.addFocusListener( ( new FocusListener( )

        {

            String promptText = "You must write the path...";



            @Override

            public void focusLost( FocusEvent e )

            {

                // TODO Auto-generated method stub

                if( jTextField.getText( ).isEmpty( ) )

                {

                    jTextField.setText( promptText );

                }

            }



            @Override

            public void focusGained( FocusEvent e )

            {

                // TODO Auto-generated method stub

                if( jTextField.getText( ).equals( promptText ) )

                {

                    jTextField.setText( "" );

                }

            }

        } ) );

    }

}

But it seems it was not much of a success. I cannot annotate my tests with many @...Test since they are now each bringing their own XxxTestContextBootstrapper. It used to work when they all used same SpringBootTestContextBootstrapper. @RunWith(SpringRunner.class) @JdbcTest @JsonTest public class Test { @Test public void test() { System.out.printn("Hello, World !"); } } The error I get from BootstrapUtils is illegalStateException : Configuration error: found multiple declarations of @BootstrapWith for test class I understand I might be doing something wrong here but is there an easy way I could load both Json and Jdbc contex...
