how to do multithreading code example
Example 1: multithreading
Example 2: multithreading in java
class Count implements Runnable
{
Thread mythread ;
Count()
{
mythread = new Thread(this, "my runnable thread");
System.out.println("my thread created" + mythread);
mythread.start();
}
public void run()
{
try
{
for (int i=0 ;i<10;i++)
{
System.out.println("Printing the count " + i);
Thread.sleep(1000);
}
}
catch(InterruptedException e)
{
System.out.println("my thread interrupted");
}
System.out.println("mythread run is over" );
}
}
class RunnableExample
{
public static void main(String args[])
{
Count cnt = new Count();
try
{
while(cnt.mythread.isAlive())
{
System.out.println("Main thread will be alive till the child thread is live");
Thread.sleep(1500);
}
}
catch(InterruptedException e)
{
System.out.println("Main thread interrupted");
}
System.out.println("Main thread run is over" );
}
}
Example 3: multithreading
from multiprocessing.pool import ThreadPool
def stringFunction(value):
my_str = 3 + value
return my_str
def stringFunctio(value):
my_str = 33 + value
return my_str
pool = ThreadPool(processes=2)
thread1 = pool.apply_async(stringFunction,(8,))
thread2 = pool.apply_async(stringFunctio,(8,))
return_val = thread1.get()
return_val1 = thread2.get()
Example 4: multithreading
class RunnableDemo implements Runnable {
private Thread t;
private String threadName;
RunnableDemo( String name) {
threadName = name;
System.out.println("Creating " + threadName );
}
public void run() {
System.out.println("Running " + threadName );
try {
for(int i = 4; i > 0; i--) {
System.out.println("Thread: " + threadName + ", " + i);
Thread.sleep(50);
}
} catch (InterruptedException e) {
System.out.println("Thread " + threadName + " interrupted.");
}
System.out.println("Thread " + threadName + " exiting.");
}
public void start () {
System.out.println("Starting " + threadName );
if (t == null) {
t = new Thread (this, threadName);
t.start ();
}
}
}
public class TestThread {
public static void main(String args[]) {
RunnableDemo R1 = new RunnableDemo( "Thread-1");
R1.start();
RunnableDemo R2 = new RunnableDemo( "Thread-2");
R2.start();
}
}
