Java 8, released in 2014, introduced significant improvements to the language and its standard library. Here are the key features:
1. Lambda Expressions
Simplify functional programming with concise syntax.
Example:
list.forEach(item -> System.out.println(item));
2. Stream API
Enhance data processing with operations like filter, map, and reduce.
🌊 Useful for handling collections efficiently!
3. Date-Time API
Replace outdated classes with java.time package.
⏰ New classes like LocalDate, LocalTime, and LocalDateTime!
4. Default Methods in Interfaces
Allow interfaces to have method implementations.
This enables backward compatibility with new features.
5. Optional Class
Reduce null checks with Optional<T> to handle potential absence of values.
