在java中是否有类似LINQ的实现？

Question

就像C＃为我提供LINQ，Java中是否有任何软件包或预处理器？

Answer 1

简单地说，不。查看Jon Skeet's answer.

Answer 2

嗯......是的！见https://github.com/nicholas22/jpropel-light

  // create alphabet char[]
  new Character('A').to(new Character('Z')).unbox();

  // join two arrays and put in list 
  alphabet.join(numerics).toList(); 

  // select distinct j* names, using LINQ-style statements
  new String[] { "james", "john", "john", "eddie" }.where(startsWith("j")).distinct();
