GS Collections ：一個Java集合框架

GS Collections是一個Java集合框架。它擁有兼容JDK的List，Set和Map實現。提供了豐富的API和一組工具類用于操作任何JDK兼容的Collections, Arrays, Maps 或 Strings。以下是一個示例代碼：

MutableList<Person> people = FastList.newListWith(person1, person2, person3);
MutableList<String> sortedLastNames = people.collect(Person.TO_LAST_NAME).sortThis();
System.out.println("Comma separated, sorted last names: " + sortedLastNames.makeString());

為什么要使用GS Collections?

• 提高可讀性和減少重復迭代代碼
• 實現了幾個，高層次的迭代模式 (select, reject, collect, inject into, etc.)擴展自JDK接口的 “人性化”容器接口。
• 為 Collections, Arrays, Maps, 和 Strings提供了一個一致的迭代機制。
• 提供替代優化性能和內存使用的ArrayList，HashSet，HashMap。
• Performs more "behind-the-scene" optimizations in utility classes
• Encapsulates a lot of the structural complexity of parallel iteration and lazy evaluation
• Adds new containers including Bag, Interval, Multimap, and immutable versions of all types
• Has been under active development since 2005 and is a mature library
