Difference Between String, StringBuilder, and StringBuffer :
- String:
- Immutability: Strings are immutable. Once created, they cannot be modified. Any change creates a new string.
- Thread Safety: Strings are thread-safe.
- Performance: Modifying strings frequently can lead to performance issues and increased memory usage.
- Usage: Best for fixed data, like constants.
- StringBuilder:
- Mutability: StringBuilder objects are mutable, allowing modifications without creating new objects.
- Thread Safety: Not thread-safe, suitable for single-threaded contexts.
- Performance: Faster than StringBuffer due to lack of synchronization overhead.
- Usage: Ideal for single-threaded applications where strings are frequently modified.
- StringBuffer:
- Mutability: Similar to StringBuilder, StringBuffer objects are mutable.
- Thread Safety: Thread-safe with synchronized methods.
- Performance: Slower than StringBuilder due to synchronization but safe for multi-threaded use.
- Usage: Suitable for multi-threaded applications requiring string modifications.
Summary
- String: Immutable, thread-safe, used for constants.
- StringBuilder: Mutable, not thread-safe, used for frequent modifications in single-threaded environments.
- StringBuffer: Mutable, thread-safe, used for multi-threaded environments.
