Display bill total, Java public void display() error -

i'm having trouble executing total bill display. asked professor gave me small block of code, modified meet needs, reason not executing , has error:

illegal start expression line --> public void display().

the compiler suggests end semi colon don't believe accurate.

what missing public void display() not being executed , erroneous?

your code structure making things difficult you. mentioned @carcigenicate, (nice name btw), have declared method inside main method. once change that, you'll notice display method shows compiler errors. because variables referenced in display no longer visible. have few options:

• rethink design of class i.e methods should exist , how called.
• take display method outside main method , make variables member variables visible methods need. read effects of using member variables first.
• remove display method , move logic main method.
