How do I add overtime?

This is supposed to read scores in a basketabll game. I can't seem to figure out why it won't read past the 4th quarter, it needs to read up until the 9th so basically from 5th-9th quarter should be considered OT. Also, how can I add the quarter label above the output score. Thanks in advance!

public static int REGULATION_NUM_QUARTERS = 4;

public static int MAX_BOX_SCORE_LENGTH = 9;

public static final int SENTINEL = -999;

private static final int AWAY = 1;
private static final int HOME = 2; 


public static void initialize (int[] awayScores, int [] homeScores ) {
	
	for (int i = 0; i < MAX_BOX_SCORE_LENGTH; i++ ){
		awayScores [i] = SENTINEL; 

	}

	for (int i = 0; i < MAX_BOX_SCORE_LENGTH; i++ ){
		homeScores [i] = SENTINEL; 
	}

}

public static void readScores(Scanner scores, int[] awayScores, int[] homeScores) {

	int team = AWAY; 
	int quarter = 1;

	while (!gameIsOver(quarter, team, awayScores, homeScores)) {

		if (team == AWAY) { 
			awayScores [quarter -1]=  scores.nextInt();
			team = HOME; 
		}

		else {
			homeScores [quarter-1]=  scores.nextInt(); 
			team = AWAY; 
			quarter++;
		}
	}
