How to implement getKeyStates() on MIDP1.0??

I am programming a game on MIDP1.0.
It requires 2 keys pressed at the same time,but there is no method in MIDP1.0 which can detect 2 keys at the same time.
Help!!

You have to set flags in the keyPressed() method and reset them in the keyReleased() method, and poll those flags in your game loop:

boolean upPressed;
boolean leftPressed;
void keyPressed(int code) {
  int action = getGameAction(code);
  if (action == UP) upPressed = true;
  // same for the rest of the keys you need
}
void keyReleased(int code) {
  int action = getGameAction(code);
  if (action == UP) upPressed = false;
  // same for the rest of the keys you need
}
// one tick of the game loop:
void tick() {
  if (upPressed && leftPressed) moveDiagonally();
  // ...
}

Not all phones support multiple keypresses though, so the keyPressed() might not get called for the second key, and in that case there is nothing you can do.
