java 43 | Thread class methods | Thread class constructors | sleep(), join () | setName (), setId()
Thread class provide constructors and methods to create and perform operations on a thread.
Thread class extends Object class and implements Runnable interface.
At the end of this class students will be able to understand:-
Thread class constructors
Thread class methods
Following is the declaration for java.lang.Thread class −
public class Thread extends Object implements Runnable
{
….
….
}
Thread class extends Object class and implements Runnable interface
constructors
Thread()
Thread(String name)
Thread(Runnable r)
Thread(Runnable r,String name)
Methods
currentThread( ): java.lang.Thread.currentThread() Returns a reference to the currently executing thread object
Syntax:
public static Thread currentThread()
Returns: the currently executing thread
run(): java.lang.Thread.run()
Syntax:
public void run()
Description: If this thread was constructed using a separate Runnable run object, then that Runnable object's run method is called; otherwise, this method does nothing and returns. Subclasses of Thread should override this method.
start(): java.lang.Thread.start() Causes this thread to begin execution; the Java Virtual Machine calls the run method of this thread
Syntax:
public void start()
Throws:
IllegalThreadStateException - if the thread was already started.
getName(): java.lang.Thread.getName() Returns this thread’s name
Syntax:
public final String getName()
Returns: this thread's name
getId(): java.lang.Thread.getId() Returns the identifier of this Thread
Syntax:
public long getId()
Returns: this thread's ID
setName(String name): java.lang.Thread.setName(String name) Changes the name of this thread to be equal to the argument name.
Syntax:
public final void setName(String name)
Parameters: name - the new name for this thread.
Throws: SecurityException - if the current thread cannot modify this thread.
isAlive(): java.lang.Thread.isAlive() Tests if this thread is alive
Syntax:
public final boolean isAlive()
Returns: true if this thread is alive; false otherwise
getPriority(): java.lang.Thread.getPriority() Returns this thread’s priority
Syntax:
public final int getPriority()
Returns: this thread's priority
setPriority(int newPriority): java.lang.Thread.setPriority(int newPriority)
Changes the priority of this thread
Syntax:
public final void setPriority(int newPriority)
Parameters: newPriority - priority to set this thread to Throws:
IllegalArgumentException- If the priority is not in the range MIN_PRIORITY to MAX_PRIORITY
SecurityException - if the current thread cannot modify this thread.
join(): java.lang.Thread.join() Waits for this thread to die
Syntax:
public final void join() throws InterruptedException
Throws:
InterruptedException - if any thread has interrupted the current thread. The interrupted status of the current thread is cleared when this exception is thrown
join(long millis): java.lang.Thread.join(long millis) Waits at most millis milliseconds for this thread to die
Syntax:
public final void join(long millis) throws InterruptedException
Parameters: millis - the time to wait in milliseconds
Throws:
IllegalArgumentException - if the value of millis is negative InterruptedException - if any thread has interrupted the current thread. The interrupted status of the current thread is cleared when this exception is thrown.
sleep(long millis): java.lang.Thread.sleep(long millis) Causes the currently executing thread to sleep (temporarily cease execution) for the specified number of milliseconds, subject to the precision and accuracy of system timers and schedulers
Syntax:
public static void sleep(long millis) throws InterruptedException Parameters: millis - the length of time to sleep in milliseconds Throws: IllegalArgumentException - if the value of millis is negative
InterruptedException - if any thread has interrupted the current thread. The interrupted status of the current thread is cleared when this exception is thrown.
summary
Thread class provides constructors and methods to create and perform operations on a thread to:-
Create and Run the thread
Set the name and id of thread
Get the name and id of the thread
Set the priority of the thread
To put itself to sleep and join after other thread is dead

भाई साहब, यह अवैज्ञानिक पद्धति - नारियल, मेटल के सड(Rodes), , अंग्रेजी Y आकारकी पेड की हरी पतली डाल, pendulum, इत्यादि का प्रयोग भूजल संशोधन के लिए नुकसानदायक होता है। वनस्पतिविज्ञान से कहां पानी है या नहीं है दरअसल देखने की पद्धति अब कालबाह्य हो गये है, क्यों कि भुगर्भमेंसे बहुत सारे पानी खींच लिया है, और भूस्तर में बहुत कम जगह पानी बचा हुआ है। अगर बोरवेल(नलकूप) और कुएं का निर्माण करने के लिए असली आधुनिक विज्ञान और तकनीक का प्रयोग किया जाता है तो वहीं पर बोरवेल और कुएं कहां पर बनाने उन जगहों को निश्चित करने के लिए कयो उपयुक्त असली आधुनिक विज्ञान और तकनीक का प्रयोग नहीं किया जाता है? हकीकत में भूगर्भ जल अनुसंधान के लिए बनावटी जर्मन और जापानी टेक्नोलॉजी की मशीन: ADMT, PQWT, PULL FINDER, जैसे मशीनों का प्रयोग नहीं करने चाहिए, बल्कि शासन प्रमाणित और युनिवर्सिटी प्रमाणित रेजिस्टीवीटी मशीनों का प्रयोग ही उचित और अधिक अपेक्षाकृत परिणाम दे सकते हैं। ज्यादा जानकारी के लिए संपर्क करें: ९८२२६४५७८७ डॉ. सुरेश पवार, पुणे, महाराष्ट्र और ९९७८११५९६८ रतिलाल सुदाणी, आणंद, गुजरात

Re साल लोटा में छेद है... सबों को चुटिया बना रहा हैं... आप लोग जरा देखे की चावल पलटते समय छेद दिखाई देता हैं
This is fact..even,stick and coconut is used to confirm the ground water for digging well/borewell
ये सब गलत है आप घर में कहीं भी बैठकर ये प्रयोग करेंगे तो ये होता है,चावल पालिस वाले न हो वो पूराने हो तो चावल मे कोई बार अंदर बाहर करने पर हवा बाहर होकर राड को पकड़ लेता है ये पहले भी देख चुका हूँ महाराष्ट्र के अंधश्रद्धा उनमूलन समिति से ज्ञान मानव जी के लोग बडी आसानी से कर दिखाते हैं और कारण भी बताते हैं।

बिना पालिश का चावल होगा तो ये कोई भी कर सकता है
