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.

Java programmers with a monthly salary of 20,000 belong to intermediate programmers. Is that the technology is a little better, and you can't do it at the architect level. Generally speaking, 20,000 of the salary depends on the following aspects.1. Whether the project can be completed independently, and what projects have been completed, at least the 6+ project.

and clear and recyclable for objects that have died in the heap or that have not been used for a long time, and the programmer cannot call the garbage collector in real time for garbage collection of an object or all objects. The recycling mechanism has generational replication garbage collection and token garbage collection, incremental garbage collection.38. What is the basic principle of the garbage collector? Can the garbage collector reclaim mem

I once wrote on many occasions that the trained Enterprise Java Development Corps only knows how to use certain frameworks, but does not know the underlying principles of these frameworks. This morning, I met this situation again during interviews for three positions. Our advisory company received a recruitment requirement from a customer and wanted a Java developer with rich experience and familiarity with

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

method has an exception, it must be done with a try and never be thrown.Summary of Knowledge points1. Inheriting classes and implementing interfacesThe parent class defines the common properties of a class of things, and the interface tends to define the extended functionality of a class of things.2. Use of Throw and throws1) The throw is defined within the function and is used to throw an exception object;2) throws defined on the function, used to throw the exception class, can be thrown multi
