Functional Programming in Java, 2nd Edition

Skipping Values

Given a collection of values, if we want to skip processing a certain number of values or until a certain condition is met, we may use the continue statement along with the if statement in the traditional for loop. In the functional style, we don’t use if or continue. Instead, we can control the iteration using the skip() or dropWhile() functions.

If you like to skip the first four values in the collection and only process the rest, pass the number of values you want to skip to the skip() function, like so:

collections/fpij/SkipElements.java

friends.stream()
       .skip(4)
       .map(String::toUpperCase)
       .forEach(System.out::println);

The call to skip() in the previous example ignores the first four values in the collection from further ...
