Henan Specialist Enrollment Online: Why learn Java

In the five years since the birth of Java technology, Java has become a catchy term for everyone, and some of the arguments are factual, and some are exaggerated and untrue. You may want to know: You should not learn Java, I give you the answer is yes, please listen to my statement. What is Java? You have to understand what Java is.

when it comes to learning programming languages, many people will thinkJava Development, then why do you learnJavadevelopment, why isJavalanguage, not other languages,Javawhat's different from other languages,Javathe advantages of where it, here to introduce you, I hope to know people who want to help.

First, simple: We all know that Java is one of the most widely used network programming languages. He is easy to learn and good to use, if you have learned C + + language, you will think C + + and Java very much like, because many basic statements in Java syntax and C + +, like the usual loop statements, control statements and so on, and C + + is almost the same, in fact, Java and C + + are two completely different languages, 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 has omitted the concepts of operator overloading, multiple inheritance and so on, many confusing concepts in C + +, some being discarded by Java, or implemented in a clearer and easier-to-understand way, so the Java language is relatively simple.

Second, security is good: when you are ready to download a software or other resources from the Internet, your biggest worry is that they have malicious code, such as the program is a virus program and so on. Since Java does not support pointers, all access to memory must be implemented through the object's instance variables, which prevents programmers from accessing the private members of the object using deceptive means such as Trojan horse, and avoids errors that are easily generated by pointer manipulation. So there is no need to worry about viral infections and malicious attempts.

Again, Multithreading: One of the features of Java is its built-in multithreading. Multithreading allows multiple tasks to be completed at the same time. C + + does not have a built-in multithreading mechanism, so you must invoke the multithreaded capabilities of the operating system to design multi-threaded threads. Multithreading enables applications to execute in parallel, and the synchronization mechanism guarantees the correct operation of shared data. By using multi-threading, programmers can use different threads to accomplish specific behaviors, instead of using the global event loop mechanism, which makes it easy to implement real-time interactive behavior on the network.

Then, the dynamic: The basic component of theJava program is the class, and the class is the runtime dynamic loading, which makes Java can be in the distribution environment to dynamically maintain the program and class library, and unlike C + +, whenever its class library upgrade, the corresponding program must be re-modified, compiled. Java is free to add new methods and instance variables to the class library without affecting the execution of the user program. and Java uses interfaces to support multiple inheritance, making it more flexible and extensible than strict class inheritance.

Furthermore, portability: Java offers one of the simplest and most familiar portability – source code porting. This means that any Java program, regardless of the CPU, operating system, or Java compiler it runs on, will produce the same result. This is not a new concept, people use C, C + + can also produce the same effect. But programming with C or C + + is not strictly defined in many details. Java's portability features make it a broad application prospect on the Internet. At the same time, its own anti-virus capability also makes it a place in applications that require high reliability.

Finally, the market prospect is big: At present, the computer language market share of the Java language of 20%, the world's first programming language. According to statistics, 2015 China's demand for software development personnel has reached 600,000, and annual growth rate of about 22%. In particular, Java programmers,Java engineers are the most lacking. In the next 5 years, the demand for qualified software developers will be far greater than the supply, it appears that the Java development market is infinitely large.

If you read this article carefully, you will know why so many people have chosen to learn Java development. After all, the eyes of the masses are discerning, learning Java development is also the trend. If you are also going to enter the software development door, then come to Henan Specialist enrollment online, learn Java development bar.
