Thread Life Cycle

title: Thread Life Cycle description: Java thread ke states aur transitions

States

NEW → RUNNABLE → RUNNING → BLOCKED/WAITING/TIMED_WAITING → TERMINATED

1. NEW

Thread object ban gaya lekin start() nahi hua.

java exampleWoHoTech

Thread t = new Thread(() -> System.out.println("Hello"));
// State: NEW

2. RUNNABLE

start() call ho gaya. Thread scheduler queue mein hai.

java exampleWoHoTech

t.start(); // State: RUNNABLE

3. RUNNING

Thread actually CPU pe execute ho rahi hai.

4. BLOCKED

Synchronized block/method ke liye lock ka wait.

5. WAITING

wait(), join() call ke baad indefinite wait.

6. TIMED_WAITING

sleep(ms), wait(ms) — specified time ke liye wait.

7. TERMINATED

run() complete ho gaya ya exception aayi.

Thread State Check karna

java exampleWoHoTech

Thread t = new Thread(() -> {
    try { Thread.sleep(1000); }
    catch (InterruptedException e) { }
});

System.out.println(t.getState()); // NEW
t.start();
System.out.println(t.getState()); // RUNNABLE or TIMED_WAITING
t.join();
System.out.println(t.getState()); // TERMINATED

Thread Methods

Method	Kaam
`start()`	Thread start karo
`run()`	Thread logic (direct call nahi karo)
`sleep(ms)`	Specified time pause
`join()`	Wait for thread to finish
`interrupt()`	Thread interrupt karo
`isAlive()`	Thread chal rahi hai?
`getName()`	Thread naam
`setName()`	Thread naam set karo
`getPriority()`	Priority get
`setPriority()`	Priority set
