List<People> peopleListPeek = peopleList.stream().filter(people -> people.getId().equals(2)).peek(people -> people.setName("peek修改实体元素值")).collect(Collectors.toList()); System.out.println("peek修改实体元素值" + peopleListPeek); // 结果为:peek修改实体元素值[People(id=2, name=...

{0}:", maxPrime); Console.WriteLine(" {0}", String.Join(" ", primes)); } private static List<int> GetPrimes(int maxPrime) { Array values = Array.CreateInstance(typeof(int), new int[] { maxPrime - 1}, new int[] { 2 }); // Use Sieve of Eratosthenes to determine prime ...
Strings =String.join("_", list); 复制代码 一行代码,就可以把list里的字符串通过“_”拼接起来。 经典的Guava guava是我们crud程序员的好伙伴,这里就不用多说了。我们最常接触到的其实就是guava的本地缓存和字符串操作。 Stringresult = Joiner.on(",").join(list); ...
Join(String, IEnumerable<String>)是一种方便的方法,可用于连接IEnumerable(Of String)集合中的每个元素,而无需先将元素转换为字符串数组。 它特别适用于 Language-Integrated 查询(LINQ)查询表达式。 以下示例将包含字母大写或小写字母的List(Of String)对象传递给 lambda 表达式,该表达式选择等于或大于特定字母的字母...
