Answer 1

hm.put(inpu, 'x') ;

But should separate input from HashMap creation otherwise it is created new one every time and cause it's no use.
And take static Scanner object at class level.

Answer 2

Martin Taylor so what can I do?

Answer 3

there might be a simpler solution, but I try keep your idea:

public class Main {
//...
static HashMap<String,Position> hm = new HashMap<>();
static Position[][] ticTacToe = new Position[3][3];

class Position {
char value = ' ';
public String toString() {return String.valueOf( value );}
}

{
for(int i=0; i<3; i++) {
for(int j=0; j<3; j++) {
ticTacToe[i][j] = new Position();
}}

hm.put("top left" , ticTacToe[0][0]);
//...
---
public static void main(String[] args) {
var m = new Main();
m.printBoard(m.ticTacToe);
while (m.goodAttemps < 9) {
m.game();
}
}
---
public static void printBoard(Position[][] arr) {
//...
---
public static void takeInputAndCheckValid() {
//...
if (containsSpot == 9) {
//...
} else {
Position position = hm.get(input);
if (position.value == ' ') {
position.value = turn;
//...
