i'm trying to make it so if the player is not holding down left or right key they character will change its image into a standing position. My teacher told me i could use || for or but i got an error. 
if(!Greenfoot.isKeyDown(right || left))
        {
            setImage("stand-2.png");
        }

Test keys individually -- then OR the results. Also key names must be between double quotes.

it keeps saying bad operand for binary operator '||' even when they were in double quotes and doing them individually doesnt work either

I see what you tried - „if either one of the left and right arrow key is down then execute this“. However, what you say with this in the inner part of the statement is „left or right“, and that would be an or between two strings. You can only use the or operator between two boolean values though. So the proper statement would be: „If either the left key is down or the right key is down then execute this“. Try to express that in java now.
