Hi i have been trying to get a GUI in BlueJ working properly but i hav come across a prolem, i hav 2 buttons which i want to use but when i click them the actionListener wont run my methods.
In the action preformed bit i tried to make it so when you pressed the button it would make the NewPatient method work but it came up with the error '.class' was expected', also when i try to use it to call the method getPatient the same error occurs. if anyone could help me with this it would be helpful
Thanks
Chris
