sounds like a good start.

did you try calling it from System.out.println when you used it before? if not, then it's a totally different scenario.

Code

System.out.println(range());

another good idea. don't return a boolean.

hmm ok ty

also... this was the code i used void with method:

Code

void range() {
System.out.println("Range is: " + fuelcap * mpg);
}

calling it:

Code

System.out.println("Sportscar can carry " + sportscar.passengers + ". ");
sportscar.range();

EDIT: So the only problem is that i wasn't using string? I'm still not sure how to use string, cuz i haven't covered that in my book yet
EDIT: btw thank you for helpnig

this is completely different from how you're using check. here, you call range outside of the print statement, so its return value is irrelevant. whereas you call check() inside of the print statement, so its return statement is very relevant.

how would i use string to replace

void check() {

I typed: string check() {

didn't work

EDIT: i also changed:

Code

void check() {
if(omnivore == true) System.out.print("omnivore");
if(carnivore == true) System.out.print("carnivore");
if(herbavore == true) System.out.print("herbavore");
}

from println to print.... i think with this way it'd be better formated?

look around 2:16. i think you'll see a familiar error message and the solution

In guessing it's self learning.

Considering he's been asking random java questions for at least 6 months; he asked for a Java buddy a month or two ago; and it's the end of April (almost final exam time) and he's doing this of all things
