Java Daemon Thread Examples

  • You can make any java thread as daemon thread. Daemon threads acts like service providers for other threads running in the same process.
  • Daemon threads will be terminated by the JVM when there are none of the other threads running, it includs main thread of execution as well.
  • To specify that a thread is a daemon thread, call the setDaemon method with the argument true.
  • To determine if a thread is a daemon thread, use the accessor method isDaemon.

Daemon Thread Sample Code

package com.myjava.threads;

public class DaemonThread extends Thread{
    
    public DaemonThread(){
        setDaemon(true);
    }
    public void run(){
        System.out.println("Is this thread Daemon? - "+isDaemon());
    }
    public static void main(String a[]){
        DaemonThread dt = new DaemonThread();
        // even you can set daemon constrain here also
        // it is like dt.setDeamon(true)
        dt.start();
    }
}

Example Output

Is this thread Daemon? - true

String Vs StringBuffer
We know that String is immutable object. We can not change the value of a String object once it is initiated. If we try to change the value of the existing String object then it creates new object rather than changing the value of the existing object. So incase, we are going to do more modificatios on String, then use StringBuffer. StringBuffer updates the existing objects value, rather creating new object.
Famous Quotations
The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.
