Java developers spend a lot of time burying themselves in Java code, using a variety of different ides (intergrated development environment) to develop Java code, so I'll introduce you to 11 different Ides, These Ides offer a variety of features such as building Java applications, TestNG, debugging, code checking, code

It industry is now in a hot stage, many people face the problem of employment after the choice of the programmer's path, Java as one of the large plate has been favored by many students, then how to learn Java correctly? Qian Feng Changsha teachers to give you an analysis of the correct Java learning route, teach you how to become a good

Imagine, in order to return two to three values, have to encapsulate an object, or erase the business name using the map, list and other collection classes, advanced point with Apache pair and triple, although feasible, but always not as elegant as the implementation of go. On top of that, go also unifies the abnormal return way, does not have to tangle is by throws the exception or the error code to judge whether succeeds,

A.D. In 2050, there was only one Java programmer left in the world. you may have to ask, where are all the other people? The reason is simple, Java is declining.about 2030 years, there has been a language called X, it can do system-level development (operating system, database, compiler), but also to do server-side development, mobile phone, web-side is not easy.

Dark Horse programmer--java Basic I. OverviewJava provides a range of tool classes for manipulating set, list, and map, mainly collections and arrays. The features of the two tool classes are: The methods in the class are static, and you do not need to create the object and call it directly using the class name. Collections: is a tool class for collection objects, provides a tool method for manipulating col
