Seat Assignment Program Problem

[Slick47]

Hey guys, I've gone one problem (so far) in my program to be able to assign and display seats. When I compile my program I get the error:

SeatAssign.java:54: setSeats(char[][]) in SeatAssign cannot be applied to (char[][],int,int)
            setSeats (Seats, row, col);
            ^
 

I have marked this line with some asterisks and was hoping we could deliberate on what the problem with it is? Thanks guys in advance.

You defined "public static void setSeats (char Seats[][]);" that initialized all the Seats, I think you need to create a new function called setSeat maybe that takes in a row and column and sets only that one row/column Seat value.

Thank you, I'll give that a try and post any problems I might have :)

@Slick47
You should've read the error message, it tells it all:

setSeats(char[][]) in SeatAssign cannot be applied to (char[][],int,int) 
 

Your compiler is trying to tell you that it found a method setSeats(char[][]) but you are trying to call it with an incompatible parameter list (char[][], int, int). That should've rang a bell. Always first read the compiler's error and/or warning messages and try to understand what it's trying to tell you.

kind regards,

Jos
