Java / Java Multithreading
How do you create a Thread?
Implement Runnable interface and its only method run(), which will have the code to be executed by the thread.
The object for the class that implements the Runnable interface is passed as an argument to the Thread constructor as explained below.
An application can use the Executor framework, in order to create a thread pool.
package com.tutorials.threading; class RunnableThread implements Runnable { @Override public void run() { System.out.println("This line is printed from a thread."); } } public class RunnableThreadExample { public static void main(String[] args) { // Runnable object is created RunnableThread myObject = new RunnableThread(); Thread myThreadObject = new Thread(myObject); myThreadObject.start(); } }
The class may extend Thread class since Thread class implements Runnable interface. The sub class run() method will provide its implementation and override Thread class method.
The thread run() method is invoked by creating object to the Extended Class and call start() method.
package com.tutorials.threading; public class ThreadExtended extends Thread { public void run() { System.out.println("The thread prints this line."); } public static void main(String args[]) { ThreadExtended myThreadObj = new ThreadExtended(); myThreadObj.start(); } }
