example north-east:

    case "ne":
        if(map.rooms[row][col].isValidExit("ne")) {
            col++;
            row--;
        }
        else {
            System.out.println("You cant go that way");
        }

you need to char-parse your input

while(!input.equals("quit"))
{
   System.out.println(map.rooms[row][col].name);
   System.out.print(">");
   input = scan.nextLine().toLowerCase();
   char[] inputArray = input.toCharArray();

   for(char c : inputArray){

    switch (input) {
        case "n":
            if(map.rooms[row][col].isValidExit("n"))
                row--;
            else
                System.out.println("You cant go that way");
            break;
        case "s":
             if(map.rooms[row][col].isValidExit("s"))
                row++;
            else
                System.out.println("You cant go that way");
             break;
        case "w":
            if(map.rooms[row][col].isValidExit("w"))
                col--;
            else
                System.out.println("You cant go that way");
            break;
        case "e":
            if(map.rooms[row][col].isValidExit("e"))
                col++;
            else
                System.out.println("You cant go that way");
            break;
