What are the advantages and disadvantages of using Stream API in Java 8?

Advantages of Stream API in Java 8:

• Allows writing concise and readable code for processing collections and data sequences.
• Supports functional programming style with operations like map, filter, reduce.
• Facilitates easy implementation of lazy computations, enhancing performance when working with large data volumes.
• Provides the ability for parallel data processing through parallel streams.

Disadvantages:

• Can be more difficult for beginners to understand due to the functional style.
• Incorrect use of parallel streams may lead to thread safety and performance issues.
• Debugging streams can sometimes be challenging due to chained calls and lazy execution.

Example of using Stream API:

List<String> names = Arrays.asList("Anna", "Bob", "Charlie");
List<String> filtered = names.stream()
    .filter(name -> name.startsWith("A"))
    .collect(Collectors.toList());
