java functional interface lambda

disadvantage , the first point is: The processing speed may be a little faster. Can adapt to different platforms, "write once, use everywhere." Disadvantages: The perception depends on the target platform. Some platforms do not have a rich interface component (early) like Windows or Mac. So the design work of AWT is limited to the "lowest common denominator". There are different bugs on different platforms. In

Introduction: PAPI is a set of local interfaces for accessing the processor hardware performance counters, and using this interface to monitor the hardware execution characteristics of the Java program will help to discover the root cause of the program performance problem on the hardware layer of the computer system. This paper introduces the important concept of PAPI and its common

uses a linked list to maintain the order of elements (in the order of insertion). So when you use iterators to traverse set, the results are displayed in the order in which the elements are inserted. the functional method of map Method put (Object key, object value) adds a "value" (What you Want) and a key that is associated with the value (used to find it). The method get (Object key) returns the value associated with the given key. You can use Cont

return of the results of multithreadingExecutorservice, callable, future This object is actually a functional class within the executor framework. To get a detailed understanding of the executor framework's accessible http://www.javaeye.com/topic/366591, the framework is explained in detail here. The thread that returns the result is a new feature introduced in the JDK1.5, which is really practical, and with this feature I don't have to bother to get

1. Object-Oriented Programming:The language of object-oriented programming is not only Java, but also:Simula 67 (the first object-oriented language, supports both single-inheritance and certain meanings of polymorphic and partial dynamic binding);Smalltalk (the first language that supports dynamic typing, supports single inheritance, polymorphism, and dynamic binding);EIFFEL (supports multi-inheritance, polymorphism and dynamic binding);C + + (most of
