Solution 1

right click on your textfield component and goto Events then goto Focus then select focus gained and the code will appear to you as private void 

    jTextField1FocusGained(java.awt.event.FocusEvent evt) {                                        
    // TODO add your handling code here:
    }

now edit the // TODO add your handling code here: and make it as:

    jTextField1FocusGained(java.awt.event.FocusEvent evt) {                                        
     jtextField.setText(""); 
    }

so when you will press tab it will gain focus (if you will press from another tab)

Solution 2

then its simple you should use an actionListener 

   private void textfieldFocusGained(java.awt.event.FocusEvent evt) {                               
   textfield.setText("");
   }

this will allow you when you press tab the control goes to next field and empty it try this (you may use this as it is in your class constructor) 

yourtextField.addFocusListener(new FocusListener() {


public void focusGained(FocusEvent e) {
    yourtextField.setText(""); 
}


public void focusLost(FocusEvent e) {

}

});

now if you are in a textfield and will press the tab button your control will go to the next field and clear its text

Solution 3

I have the instructions for what the user is supposed to enter

See Text Prompt. It allows you to customize when the prompt is displayed.

Solution 4

You can use a FocusListener to determine when your JTextField receives focus (i.e. becomes the "active" component), regardless of whether this occurred due to a mouse click or a tab.

textField.addFocusListener(new FocusListener() {

    @Override
    public void focusGained(FocusEvent e) {
        textField.setText(null); // Empty the text field when it receives focus
    }

    @Override
    public void focusLost(FocusEvent e) {
        // You could do something here when the field loses focus, if you like
    }

});

    I'm working on a gui that has multiple textfields that the user enters data into. When the program opens, I have the instructions for what the user is supposed to enter into the textfield set as the "text". I have it set to when user clicks textfield, the text will disappear, but I can't figure out how to get it to disappear when tabbed over into the next jtextfield. I want the user to be able to click on the first textfield, and never have to use the mouse again, but also without having to go crazy on the backspace or del. Thanks

      how do you make the text in a textfield disappear when you tab into the textfield. It is easy to make it disappear when you mouse click into the textfield, maybe not quite so easy for tab

    it says the method is not used. I put it with all of the other methods that clears the textfield when mouse is clicked.
