Is lesson me hum seekhenge:

• Thread control methods
• Thread scheduling kya hota hai
• Scheduler ka role
• Important methods (sleep, yield, join)
• Real examples

Thread control ka matlab:

thread ke execution ko manage aur control karna

Thread scheduling ka matlab:

CPU decide karta hai kaunsa thread kab execute hoga

OS scheduler threads ko manage karta hai

✔ kaunsa thread run karega
✔ kitni der tak run karega

high priority thread → low priority ko interrupt kar sakta hai

har thread ko thoda-thoda CPU time milta hai

Thread.sleep(1000); // 1 second pause

✔ current thread pause hota hai
✔ InterruptedException handle karna padta hai

Thread.yield();

✔ current thread CPU chhod deta hai
✔ dusre threads ko chance deta hai

⚠ guarantee nahi hoti execution ki

t1.join();

✔ current thread wait karta hai jab tak t1 complete na ho

class Test extends Thread {

    public void run(){

        for(int i = 1; i <= 3; i++){

            try {
                Thread.sleep(1000);
            } catch(Exception e){}

            System.out.println(i);
        }
    }

    public static void main(String[] args){

        Test t = new Test();
        t.start();
    }
}

class Test extends Thread {

    public void run(){
        System.out.println(Thread.currentThread().getName());
        Thread.yield();
    }

    public static void main(String[] args){

        Test t1 = new Test();
        Test t2 = new Test();

        t1.start();
        t2.start();
    }
}

class Test extends Thread {

    public void run(){
        System.out.println("Thread running");
    }

    public static void main(String[] args) throws Exception {

        Test t1 = new Test();

        t1.start();
        t1.join();

        System.out.println("Main thread finished");
    }
}

New → Runnable → Running → Waiting → Terminated

✔ scheduler OS dependent hota hai
✔ priority sirf hint hoti hai
✔ yield guaranteed nahi hai
✔ join execution order control karta hai

Teacher class me students ko chance deta hai bolne ka

Scheduler decide karta hai kaun kab bolega.

1. Thread scheduling kya hota hai?
2. sleep(), yield(), join() me difference?
3. scheduler ka role kya hai?
4. time slicing kya hota hai?

Is lesson me humne seekha:

✔ Thread control methods
✔ Scheduling concepts
✔ sleep(), yield(), join()
✔ Thread lifecycle

Thread control aur scheduling Java me efficient execution aur resource sharing ke liye important hai.
