How to check if thread ID exists in multi-threading

[newcoder1010]

Hello,

First Test:

public class FirstTest extends GridSessionBase {

	@Test
	public void test1() {
		System.out.println("First test");
		printSessionThreadID();
	}


}

Second Test:

public class SecondTest extends GridSessionBase{

    
    @Test
    public void test1() {
        System.out.println("Second test");
        printSessionThreadID();
    }

}

Base:

public class GridSessionBase{
	WebDriver driver;
	
    // invoked once before executing each @Test method
	@BeforeMethod
	public void beforeMethod(Method method) {
		System.setProperty("webdriver.chrome.driver", "Automation_Tools\\ChromeDriver\\chromedriver.exe");
		driver = new ChromeDriver();

		System.out.println("beforeMethod");
		SessionId s = ((RemoteWebDriver) driver).getSessionId();
		System.out.println("Before method session ID: " + s);		
        long id = Thread.currentThread().getId();
		System.out.println("Before method thread ID: " + id);		
	}

// all the tests are calling this method.
public synchronized void printSessionThreadID() {
		System.out.println("printSessionThreadID");
		SessionId s = ((RemoteWebDriver) driver).getSessionId();
		System.out.println("Session ID: " + s);		
        long id = Thread.currentThread().getId();
		System.out.println("Thread ID: " + id);	

		// if session id and thread id match
//		if() {
//			// print class name and test method name of the caller
//		}		
		
	}
}

XML file to run the tests in parallel:

Below I have two <test> tags. It means all the TestNG methods listed in each <test> tag will run in the same thread. Test1 will run in one thread and Test2 will run in another thread. Both <test> tags will run in parallel. 

<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
<suite name="Access Regression Suite" parallel="tests">

	<test name="Test1">
		<classes>
			<class name="GridSessionJava.FirstTest"/>
		</classes>
	</test>

	<test name="Test2">
		<classes>
			<class name="GridSessionJava.FirstTest" />
			<class name="GridSessionJava.SecondTest" />
		</classes>
	</test>
	
</suite>

When I run xml file, here is the output:

printSessionThreadID() is being called three times. In printSessionThreadID() method, I like to know which test is calling this method. How do I write if statement in printSessionThreadID() method to check if session ID and thread ID match(or just matching thread ID) and print a message afterward?
