Quietly tell you the need to learn Java

Java is a software development classmate most familiar with a development language, ancient but very popular, coupled with the current development of Android development is a good, but also to the charm of Java. Many students want to participate in Java training, but have doubts, do not know the value is not worth to study, that this small part of the six to everyone to learn Java development reasons, hope to help you. (also from now on, I will insist on daily forwarding or publishing an article, from the most basic start, I hope to revisit it, but also for beginners to help, what are the questions welcome to leave a message or private messages, I see will reply to you. ）

 

First, simple . Java is currently the most widely used network programming language, easy to learn C + + students should have a sense of Java and C + +, it is true that many of the basic statements in Java syntax and C + +, so it is easier for students of the university computer Learning Java. Java just needs to understand some basic concepts, and it can use it to write applications that are suitable for a variety of situations. Java omits the concepts of operator overloading, multiple inheritance, and so on, or in a clearer and easier-to-understand way, simpler than C + +.

      Second, good security . When you download some software on the Internet, the most worrying thing is whether there is malicious code or virus in the software. Java does not support pointers, all access to memory must be through the object's instance variables to implement, so as to prevent Trojans and other deceptive means, it appears that the Java language security is excellent.    

      Third, multithreading . The biggest feature of Java is the built-in multi-threading mechanism that enables applications to execute in parallel. By using multi-threading, developers can perform specific behaviors with different threads, without the need for a global event loop mechanism, so that real-time interaction is easy to achieve.

Iv. Dynamic Nature . The basic components of Java are classes, and classes are dynamically loaded at runtime, so Java can dynamically maintain programs and class libraries in a distributed environment, and when the class library upgrades the corresponding program, it does not need to be re-modified. Java is free to add new methods and instance variables to the class library without affecting the execution of the user program, and Java can support multiple inheritance through interfaces, which is more flexible and extensible.

V. portability . This feature of Java allows the program to produce the same results regardless of which CPU, operating system, or Java compiler is running. This feature has a wide application prospect on the Internet.

VI, The market outlook is large . At present, java language in the market share of 20%, ranked first in the world. According to statistics, the demand for Java development talent is growing at about 22% a year. In the next 5 years, there will be a shortage of qualified software developers (according to the relevant information), so the prospects for Java development is very good.

So, what are you waiting for? ），（？ Let's start the Java journey together. Welcome to the Novice, the great God and other all corners of all kinds of friends to communicate with ....
