title: How to identify which button the mouse has entered using mouse listener in Dr Java
body: <p>how do I set the Jlabel info3 to different text messages depending on which button the mouse hovers over? Right now I do not know how to distinguish which button the mouse is currently hovering over. Here is my code</p>
  
  <pre><code>import javax.swing.*;//You need these two libraries to do the GUI stuff

  { 
  
    // *** CREATE THE GUI COMPONENTS: Here we are only creating the following: Buttons, Labels, and Text field
  
    //buttons
    JButton EI = new JButton ("Emotional intelligence");//emotional intelligence test button
    JButton MI = new JButton ("Multiple intelligences");//multiple intelligences test
    JButton MB = new JButton ("Myers-Briggs assessment");//myers-briggs assessment
    JButton LS = new JButton ("Learning styles");//learning styles test
    JButton CP = new JButton ("Career preferences");//career preferences test
  
    //panels
    JPanel p1 = new JPanel();// panel for the information
    JPanel p2 = new JPanel();//panel for the selection of tests
    JPanel p3 = new JPanel();// panel to display information on the tests
