The Java program gives me the error message: Invalid start of expression?

I use the Notepad app on the Windows operating system to write Java code. Using the "Command Prompt" program, I convert the code into bytecode using JDK-22. My code displays an error message that I don't understand. The exact error message is:

Game1.java:48: Error: Invalid start of expression

private static void movePlayer(Point playerPosition) {

^

1 error

My code is:

import java.awt.Point;

import java.util.Scanner;

public class Game1 {

public static void main(String[] args) {

Point player position = new Point(10, 9);

Point queueposition = new Point(30, 2);

Point key position = new Point(6, 6);

Point door position = new Point(2, 5);

boolean program = true;

boolean keyjn = false;

while (program) {

for (int y = 0; y < 10; y++) {

for (int x = 0; x < 40; x++) {

Point p = new Point(x, y);

if (p.equals(player position)) {

System.out.print("P");

}

else if (p.equals(queuePosition)) {

System.out.print("S");

}

else if (p.equals(keyposition) && keyjn == false) {

System.out.print("G");

}

else if (p.equals(door position)) {

System.out.print("T");

}

else {

System.out.print(".");

}

}

System.out.println("");

}

if (snakeposition.equals(playerposition)) {

program = false;

System.out.println("GAME OVER!");

}

if (player position.equals(key position)) {

keyjn = true;

}

if (playerposition.equals(doorposition) && keyjn == true) {

program = false;

System.out.println("Congratulations, you escaped the snake");

System.out.println("Play again(1), End game(2)");

movePlayer(playerposition);

movequeue(queueposition, playerposition);

}

}

private static void movePlayer(Point playerPosition) { // The error message

Scanner scan = new Scanner(System.in);

String input = scan.nextLine();

if (input.equals("w") && playerposition.y >= 1) {

playerposition.y–;

}

else if (input.equals("s") && playerposition.y <= 8) {

playerposition.y++;

}

else if (input.equals("a") && player position.x >= 1) {

playerposition.x–;

}

else if (input.equals("d") && playerposition.x <= 38) {

playerposition.x++;

}

}

private static void moveQueue(Point queuePosition, Point playerPosition) {

if (queueposition.x < playerposition.x) {

queueposition.x++;

}

else if (snakeposition.x > playerposition.y) {

queueposition.x–;

}

if (snakeposition.y < playerposition.y) {

snakeposition.y++;

}

else if (snakeposition.y > playerposition.y) {

snakeposition.y–;

}

}

}

I've been searching for the problem for over an hour but haven't found it. I hope you can help me. Thanks in advance for your answers.
