How to re-run failed tests in TestNG using IRetryAnalyzer

RetryAnalyzer.java

import org.testng.ITestResult;

public class RetryAnalyzer implements IRetryAnalyzer {

    private int retryCount = 0;
    private static int maxNumberOfRetriesForUnstableTests = 2;

    private static int relaxDayMaxNumberOfRetries = 10;
    private static String rushDay = "Monday";
    private static String relaxDay = "Thursday";

    public boolean retry(ITestResult result) {
        retryCount++;
        if (isRushDayToday()) return false;
        if (isRelaxDayToday() && retryCount <= relaxDayMaxNumberOfRetries)  return true;

        if (retryCount <= maxNumberOfRetriesForUnstableTests) return true;

    }
