Multithreading in Java
Difference Between Multithreading and Single-Threading
Single-Threading
Single-threading means that the program executes tasks one after another. Only one instruction is executed at any given time, and the other instructions wait for their turn.
Imagine a person who can only do one thing at a time: either read a book or eat a sandwich, but not at the same time.
Multithreading
Multithreading, on the other hand, allows a program to perform tasks simultaneously. Multiple instructions can be executed in parallel, in different threads.
Imagine the same person but with two hands: now he can read a book with one hand and eat a sandwich with the other hand.
Benefits of Multi-threading:
- Improved responsiveness: A multithreaded application can appear more responsive than a single-threaded application because it can simultaneously process user input and perform other tasks;
- Improved performance: A multithreaded application can take advantage of multi-core processors by distributing tasks across multiple cores;
- Efficient resource utilization: Multithreading can help utilize system resources such as memory and CPU time more efficiently.
Disadvantages of Multithreading:
- Complexity: Multithreaded programming can be more complex than single-threaded programming because multiple threads must be coordinated and conflicts must be avoided;
- Errors: Multithreaded programs may experience errors related to synchronization and access to shared resources;
- System load: Multithreaded applications can put additional load on the system, especially if they are not optimized.
