有没有一种简洁的方法来迭代流,同时有权访问流中的索引？

String[] names = {"Sam","Pamela", "Dave", "Pascal", "Erik"};

List<String> nameList;
Stream<Integer> indices = intRange(1, names.length).boxed();
nameList = zip(indices, stream(names), SimpleEntry::new)
        .filter(e -> e.getValue().length() <= e.getKey())
        .map(Entry::getValue)
        .collect(toList());

与那里给出的LINQ示例相比,这似乎相当令人失望

string[] names = { "Sam", "Pamela", "Dave", "Pascal", "Erik" };
var nameList = names.Where((c, index) => c.Length <= index + 1).ToList();

有更简洁的方法吗？

此外,看起来拉链已移动或被移除......
