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.

class SeatAssign{


final static int ROWS = 14;
final static int COLS = 7;

//MAIN MAIN MAIN MAIN
public static void main (String[] args){


	char[][] Seats;
	char seat;
	int opt;
	Seats = new char[ROWS][COLS];
	Scanner scanner;
	scanner = new Scanner(System.in);

	setSeats(Seats);

	System.out.println("Welcome to Seat Selector Pro! The realistic seat selection program!");

do{

	System.out.println();
	System.out.println("Please select an option:\n 0:Exit \n 1:Display Seats \n 2:Book a seat");//choose opt area
	opt = scanner.nextInt();

	if (opt == 0)
		return;
	else if (opt == 1)
		DisplaySeats(Seats);                                   //call up the DisplaySeats function



	else if (opt == 2){

	int row, col;
	char seatseat;

	System.out.print("Please enter a row number <1-13>:");
		row = scanner.nextInt();
		System.out.print("Please enter a column number <1-6>:");
		col = scanner.nextInt();

	*************seatseat = getSeat (Seats, row, col);*************

		if (seatseat == 'o'){
			setSeats (Seats, row, col);
			DisplaySeats (Seats);

		System.out.println("Seat is occupied.");

		                                       //call up the setSeats function

	}


	else

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 :)

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

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,
