A thread is a flow of execution through the process code,
with its own program counter that keeps track of which instruction to execute next,
system registers which hold its current working variables,
and a stack which contains the execution history.
A thread is also called a lightweight process.java thread
public class ClassName extends Thread{
public void run(){
super.run();
//Your Code
}
}
public class Main{
public static void main(String[] args){
ClassName thread = new ClassName();
thread.start();
}
}threads java
// Copy and test
// They run simultaneously
public static void main(String[] args) {
// How to create a thread
Thread thread = new Thread(new Runnable() {
@Override
// Loop running in thread
public void run() {
for (int i = 0; i < 20; i++) {
System.out.println("Printing plus " + i + " in a worker thread.");
try {
Thread.sleep(1000);
} catch(Exception e) {
e.printStackTrace();
}
}
}
});
thread.start();
// Loop running in main thread
for (int j = 0; j < 20 ; j++) {
System.out.println("Printing plus " + j + " in a main thread.");
try {
