Thread (java-runtime 7.0.21 API)

java.lang.Object
- java.lang.Thread

All Implemented Interfaces:

Runnable
```
public class Thread
extends Object
implements Runnable
```
A thread is a thread of execution in a program. The Java Virtual Machine allows an application to have multiple threads of execution running concurrently.

Field Summary

Fields
Modifier and Type	Field and Description
`static int`	`MAX_PRIORITY` The maximum priority that a thread can have.
`static int`	`MIN_PRIORITY` The minimum priority that a thread can have.
`static int`	`NORM_PRIORITY` The default priority that is assigned to a thread.

Constructor Summary

Constructors
Constructor and Description
`Thread()` Allocates a new Thread object.
`Thread(Runnable target)` Allocates a new Thread object with a specific target object whose run method is called.
`Thread(Runnable target, String name)` Allocates a new Thread object with the given target and name.
`Thread(String name)` Allocates a new Thread object with the given name.

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`static int`	`activeCount()` Returns the current number of active threads in the virtual machine.
`static Thread`	`currentThread()` Returns a reference to the currently executing Thread object.
`String`	`getName()` Returns this thread's name.
`int`	`getPriority()` Returns this thread's priority.
`StackTraceElement[]`	`getStackTrace()`
`void`	`interrupt()` Interrupts this thread.
`boolean`	`isAlive()` Tests if this thread is alive.
`void`	`join()` Waits for this thread to die.
`void`	`run()` 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.
`void`	`setPriority(int newPriority)` Changes the priority of this thread.
`static void`	`sleep(long millis)` Causes the currently executing thread to sleep (temporarily cease execution) for the specified number of milliseconds.
`void`	`start()` Causes this thread to begin execution; the Java Virtual Machine calls the run method of this thread.
`String`	`toString()` Returns a string representation of this thread, including the thread's name and priority.
`static void`	`yield()` Causes the currently executing thread object to temporarily pause and allow other threads to execute.

- Field Detail
  - MAX_PRIORITY
```
public static final int MAX_PRIORITY
```
    The maximum priority that a thread can have. See Also:Constant Field Values

  - MIN_PRIORITY
```
public static final int MIN_PRIORITY

- Constructor Detail
  - Thread
```
public Thread()
```
    Allocates a new Thread object. Threads created this way must have overridden their run() method to actually do anything.
  - Thread
```
public Thread(Runnable target)
```
    Allocates a new Thread object with a specific target object whose run method is called. target - the object whose run method is called.
  - Thread
```
public Thread(Runnable target,
              String name)
```
    Allocates a new Thread object with the given target and name. target - the object whose run method is called.name - the name of the new thread.
  - Thread
```
public Thread(String name)
```
    Allocates a new Thread object with the given name. Threads created this way must have overridden their run() method to actually do anything. name - the name of the new thread.
- Method Detail
  - activeCount
```
public static int activeCount()
```
    Returns the current number of active threads in the virtual machine.
  - currentThread
```
public static Thread currentThread()
```
    Returns a reference to the currently executing Thread object.
  - getName
```
public final String getName()
```
    Returns this thread's name. Note that in CLDC the name of the thread can only be set when creating the thread.
  - getPriority
```
public final int getPriority()
```
    Returns this thread's priority.
  - interrupt
```
public void interrupt()
```
    Interrupts this thread. In an implementation conforming to the CLDC Specification, this operation is not required to cancel or clean up any pending I/O operations that the thread may be waiting for.
  - isAlive
```
public final boolean isAlive()
```
    Tests if this thread is alive. A thread is alive if it has been started and has not yet died.
  - join
```
public final void join()
                throws InterruptedException
```
    Waits for this thread to die.
    
    Throws:
    
    InterruptedException
  - run
```
public void run()
```
    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.
    
    Specified by:
    
    run in interface Runnable
  - setPriority
```
public final void setPriority(int newPriority)
```
    Changes the priority of this thread.
  - sleep
```
public static void sleep(long millis)
                  throws InterruptedException
```
    Causes the currently executing thread to sleep (temporarily cease execution) for the specified number of milliseconds. The thread does not lose ownership of any monitors.
    
    Throws:
    
    InterruptedException
  - start
```
public void start()
```
    Causes this thread to begin execution; the Java Virtual Machine calls the run method of this thread. The result is that two threads are running concurrently: the current thread (which returns from the call to the start method) and the other thread (which executes its run method).
  - toString
```
public String toString()
```
    Returns a string representation of this thread, including the thread's name and priority.
    
    Overrides:
    
    toString in class Object
  - yield
```
public static void yield()
```
    Causes the currently executing thread object to temporarily pause and allow other threads to execute.
  - getStackTrace
```
public StackTraceElement[] getStackTrace()
```
