If语句中的2D数组

Question

I've created a 2D Array in Java that stores seatnumbers(row, column). I've initialized the array so that all values start out as 0, and if the seat is later occupied using another method Sit, the value at that coordinate is 1.

Here is the intializing:

int[][] seatlist= new int[FIRSTCLASS/3][3];           


for (int i=0; i<= FIRSTCLASS/3; i++) 
     {  
        for (int j=0; j<3; j++) 
      { 
         seatlist[i][j]=0;

       }
    }

and here is my method:

public boolean canSit(int seatrow, int seatcolumn)
{ 
    if(seatlist[seatrow-1][seatcolumn-1]==0) 
    { 
        return true;
    } 
    else 
        return false; 
}

When I try compiling, I keep getting an "array required, but int found" error on the if statement line. I can't identify the problem- can anyone help?

Thanks in advance!

Try this.

Integer[][] seatlist= new Integer[FIRSTCLASS/3][3];

or

int[FIRSTCLASS/3][3] seatlist;
