LogRecord getThreadID() method in Java with Examples

The getThreadID() method of java.lang.reflect.LogRecord is used to get an identifier for the thread where the message originated. This method is helpful to identify thread which generates the logger message.

Syntax:

public int getThreadID()

Parameters: This method accepts nothing.

Return: This method returns thread ID.

Below programs illustrate getThreadID() method:
Program 1:

// Java program to illustrate
// getThreadID() method

import java.util.logging.Level;
import java.util.logging.LogRecord;

public class GFG {

    public static void main(String[] args)
    {

        // Create LogRecord object
        LogRecord logRecord
            = new LogRecord(Level.SEVERE,
                            "Hello Logger");

        // get Thread ID
        int id = logRecord.getThreadID();

        // print
        System.out.println(
            "Thread ID = "
            + id);
    }
}

Output:

Thread ID = 1

Program 2:

// Java program to illustrate
// getThreadID() method

import java.util.logging.Level;
import java.util.logging.LogRecord;

public class GFG {

    public static void main(String[] args)
    {
        // start the Thread
        Thread thread1 = new Thread1();
        thread1.start();

        // Create LogRecord object
        LogRecord logRecord
            = new LogRecord(Level.SEVERE,
                            "Hello Logger");
        logRecord.setThreadID((int)thread1
                                  .getId());

        // get Thread ID
        int id = logRecord.getThreadID();

        // print
        System.out.println(
            "Thread ID = "
            + id);
    }
}

class Thread1 extends Thread {
    public void run()
    {
        System.out.println("Thread is running...");
    }
}

Output:

Thread is running...
Thread ID = 11
