Name
Thread
Synopsis
A class that represents a thread of execution in the Java virtual machine. Each thread has its own call stack and its own copy of local variables created by the Java methods that it executes.
An application may create a new thread of execution by instantiating a
subclass of Thread and overriding the
run() method, or by implementing a
Runnable interface and passing its reference to the
Thread constructor. A new thread is created in an inactive
state. To begin execution, its start() method must be
invoked. The total number of threads in existence can be obtained by calling
the static activeCount() method.
Once a thread is running, it continues to do so until the
run() of the Thread subclass
terminates, or the Runnable returns control to
its caller. Note that even though its thread of execution has ended, a
Thread object continues to exist until
all references to it have been released and the object is removed by the
garbage collector. The isAlive() method can be used to
determine whether a Thread object still has an active
thread of execution.
Unlike J2SE, the CLDC Thread class does not provide the
stop(), suspend() and
resume() methods. However, there are two
Thread methods that allow a thread to suspend its own
execution. The static sleep() method suspends the thread for a fixed period of time specified in milliseconds. The thread will be scheduled for resumption when the delay period expires, but may not resume immediately if another thread is currently running. ...
