Multithreading example in Java

Any application can have multiple processes (instances). Each of this process can be assigned either as a single thread or multiple threads.

What is Single Thread?

Single threaded processes contain the execution of instructions in a single sequence. In other words, one command is processes at a time.

Example:

What is Multithreading in Java?

The opposite of single threaded processes are multithreaded processes. These processes allow the execution of multiple parts of a program at the same time.

This is an animated example for a deep understanding:

Its source code:

Advantages of Multithreaded Processes:

• Enhanced performance by decreased development time
• Simplified and streamlined program coding
• Improvised GUI responsiveness
• Simultaneous and parallelized occurrence of tasks
• Better use of cache storage by utilization of resources
• Decreased cost of maintenance
• Better use of CPU resource

Disadvantages of Multithreaded Processes:

• Complex debugging and testing processes
• Overhead switching of context
• Increased potential for deadlock occurrence
• Increased difficulty level in writing a program
• Unpredictable results
