Multi-threading allows a single program to execute multiple programs simultaneously by utilizing CPU processing time more efficiently and reducing idle time. Threads can be created by implementing the Runnable interface or extending the Thread class and go through life cycle stages of new, runnable, blocked, and dead. The join method allows a parent thread to wait for child threads to terminate before ending, and synchronization techniques ensure shared resources are accessed properly between threads.
Multi threading
- 2. MULTI-THREADING Definition: Process of executing a number of programs through a single program. The purpose of multi-threading program is to utilize the CPU processing time in maximum and to reduce CPU idle time.
- 3. THREAD By default, a program is known as single threaded program as it normally follows a single line of execution.
- 4. CREATION OF THREADS Threads can be created in two ways: By implementing “Runnable Interface” By extending “Thread Class”
- 5. THREAD LIFE CYCLE NEW (BORN) RUNNABLE BLOCKED DEAD Start( ) Stop( ) Run( ) Suspend( ) Wait( ) Sleep( ) Resume( ) Notify( ) Stop( ) Run( ) Stop( ) Run( )
- 6. JOIN METHOD It forces the parent thread to wait for the termination all of its child threads i.e. the parent thread exists in memory till the termination of all of its child threads.
- 7. THREAD CLASS String getname( ) Int getpriority( ) Set priority(in) Current Thread
- 8. SYNCHRONISATION Technique of sharing a common resource between multiple threads
