How to create Daemon Threads in Java? This knowledge is crucial for those studying Daemon Threads, wanting to delve deeper into Threads in Java, and distinguishing it from regular Threads. If you're eager to learn more about Daemon Threads and how to create them in Java, don't miss out on the insights below.

What are Daemon Threads?
Firstly, you need to understand that Daemon Threads are crucial in Java, serving the purpose
Creating Daemon Threads in Java involves garbage collection, meaning it collects unused resources to free up memory. When all user threads are no longer active, the garbage collection thread also stops.
Creating Daemon Threads in Java
Step 1: To create Daemon Threads in Java, meaning an active thread or WorkingThread, execute the following command:
package com.gpcoder.daemonthread;
public class WorkingThread implements Runnable {
@Override
public void run() {
while (true) {
processSomething();
}
}
private void processSomething() {
try {
System.out.println('Processing working thread');
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
Step 2: In case you don't want to use Daemon Threads, also known as Non-Daemon Threads, declare as follows in Java:
package com.gpcoder.daemonthread;
public class NonDaemonThreadTest {
public static void main(String[] args) throws InterruptedException {
Thread dt = new Thread(new WorkingThread(), 'My Non-Daemon Thread');
dt.start();
// continue program
Thread.sleep(3000);
System.out.println('>>< finishing='' main=''>
}
}
After creating Daemon Threads in Java, the result will be as follows. As you can see, the Non-DaemonThread runs concurrently with the MainThread. When the MainThread finishes, the Non-DaemonThread continues processing until completion.
Step 3: Create a Daemon Threads in Java, a complete program with the command.
package com.gpcoder.daemonthread;
public class DaemonThreadTest {
public static void main(String[] args) throws InterruptedException {
Thread dt = new Thread(new WorkingThread(), 'My Daemon Thread');
dt.setDaemon(true);
dt.start();
// continue program
Thread.sleep(3000);
System.out.println('>>< finishing='' main=''>
}
}
And the outcome after creating Daemon Threads in Java and running Daemon Threads concurrently with MainThread. When MainThread concludes, all DaemonThreads also terminate.
Java categorizes threads into two types: regular Threads and Daemon Threads. They only differ in how they stop. Thus, the guide above has assisted you in creating Daemon Threads in Java. Mytour hopes that the knowledge we've shared partially enhances your understanding of Daemon Threads and Java.
In Java, there is a plethora of knowledge to grasp to become proficient in this language. For instance, declaring Java variables is a fundamental skill and essential knowledge for beginners. If you haven't mastered this principle, don't worry, as you can review how to declare Java variables right here.
