Milleks on mõeldud meetod limit() voogudes?

The limit(long maxSize) method in the Java Stream API is designed to create a new stream containing the elements of the original stream in a quantity that does not exceed maxSize. It is an intermediate operation that discards remaining elements after processing the specified amount.

Main effects:

• Size limitation: Applies a restriction on the maximum number of elements in the resulting stream.
• Laziness: The calculation of elements occurs only when they are actually requested by a terminal operation, until the set limit is reached.
• Truncation possibility: If the original stream contains more elements than maxSize, the stream will be truncated to maxSize elements. If fewer, all available elements are used.

Usage example:

List<String> names = Arrays.asList("Alice", "Bob", "Charlie", "David", "Eve");

List<String> firstTwoNames = names.stream()
                                  .limit(2) // Limit the stream to the first two elements
                                  .collect(Collectors.toList()); // Collect into a list

// firstTwoNames will contain ["Alice", "Bob"]
