THREAD CREATION IN JAVA
Java
is a multi threaded programming language which means we can develop multi
threaded program using Java. A multi threaded program contains two or more
parts that can run concurrently and each part can handle different task at the
same time making optimal use of the available resources specially when your
computer has multiple CPUs.By definition multitasking is when multiple
processes share common processing resources such as a CPU. Multi threading
extends the idea of multitasking into applications where you can subdivide
specific operations within a single application into individual threads. Each
of the threads can run in parallel. The OS divides processing time not only
among different applications, but also among each thread within an
application.Multi threading enables you to write in a way where multiple
activities can proceed concurrently in the same program.
TYPES OF CREATING THREAD:-
1.
IMPLEMENTING
RUNNABLE INTERFACE
2.
EXTENDING
THREAD CLASS
3.
ANONMYOUS
THREAD CLASS
4.
ANONMYOUS
RUNNABLE INTERFACE THREAD
5.
LAMBDA
ANONMYOUS RUNNABLE THREAD
TYPE 1-CREATING
THREAD USING IMPLEMENTING RUNNABLE INTERFACE
public class Runnablethre implements Runnable
{
static
Thread ti;
Runnablethre()
{
System.out.println("Strating
thread..");
}
@Override
public
void run()
{
System.out.println("running
thread..");
try
{
Thread.sleep(100);
System.out.println("NAME
OF THE THREAD.."+ti.getName());
System.out.println("PRIORITY
OF THE THREAD.."+ti.getPriority());
}
catch (InterruptedException ex) {
Logger.getLogger(Runnablethre.class.getName()).log(Level.SEVERE,
null, ex);
}
System.out.println("thread
Excited..");
}
public
static void main(String args[])
{
Runnablethre
re=new Runnablethre();
System.out.println("Creating
thread..");
ti=new
Thread(re);
ti.start();
}
}
TYPE 2- CREATING THREAD BY EXTENDING THREAD CLASS
public
class ExtendThread extends Thread
{
public
void run()
{
System.out.println("running
thread");
}
public
static void main(String args[])
{
Thread
t1=new Thread(new ExtendThread());
t1.start();
}
}
TYPE 3-ANONMYOUS THREAD
public
class AnonmyThread
{
public
static void main(String args[])
{
Thread
t1=new Thread()
{
public
void run()
{
System.out.println("THREAD
CREATED..");
}
};
t1.start();
}
}
TYPE 4- ANONMYOUS RUNNABLE INTERFACE
THREAD
public
class AnonmyRunn
{
public
static void main(String args[])
{
Runnable
r1=new Runnable()
{
@Override
public
void run() {
System.out.println("THREAD
CREATED..");
}
};
Thread
t1=new Thread(r1);
t1.start()
}
}
TYPE 5- LAMBDA ANONMYOUS RUNNABLE THREAD
public
class lAMBDAthread
{
public
static void main(String args[])
{
Runnable
task2 = () -> {
System.out.println("Task
#2 is running");
};
new
Thread(task2).start();
}
}
