Input has many methods for efficiently reading primitives and strings from bytes. It provides functionality similar to DataInputStream, BufferedInputStream, FilterInputStream, and ByteArrayInputStream, all in one class. Tip: Input provides all the functionality of ByteArrayInputStream. There is seldom ...
// Trailing empty strings are therefore not included in the resulting array. String[] words = inputLine.split("[ \n\t\r.,;:!?(){}]"); for (String word : words) { String key = word.toLowerCase(); // remove .toLowerCase for Case Sensitive result. if (key.length() > 0) {...

Laziness-seeking. Many stream operations, such as filtering, mapping, or duplicate removal, can be implemented lazily, exposing opportunities for optimization. For example, "find the firstStringwith three consecutive vowels" need not examine all the input strings. Stream operations are divided into in...
