"Void methods cannot return a value" - processing 3 in java

Question

I'm working on a snake game in java, and I made a "void" function inside a snake class, that returns if the snake eats the food. when trying to execute, the console shows me "Void methods cannot return a value". how could you return a "true" or "false" inside the "void" function?

Thanks for any help! Alon.

Answer 1

By definition, void means that the function doesn't return anything. You can still return; (with no value) to end the function early, but you can't return with a value.

To return a boolean, change void to boolean.
