Above is the code that i have done for my course so far. I am having a few problems though. I have made a few text fields invisible but do not know how to get the rest of the writing invisible(the g.drawstrings for name, hose number and postcode). Also i would like the first button to make the code visible again. The other button should delete and information that has been inputted.

Thanks in advance guys i need help today preferably as the coursework needs to bein at 2pm tomorrow.

update : the only part of the work i need help on now is the edit button so that it will delete the information from the text area and text fields.

so far i have got

if (event.getSource()==edit){

i just dont know what code will delete all the data that has been inputted into the applet
