Question

我有以下Java代码

┌─[ricardoramos]@[falcon]:~/Projetos Eclipse/LOCAL-ClienteREST

使用以下命令时，为什么不显示任何内容：

List<String> sorted = map.entrySet().stream()
                         .sorted(reverseOrder(comparing(Entry::getValue)))
                         .map(Entry::getKey)
                         .collect(toList());

怎么了？

什么是标准输出领班？
