Where is the best Java training in Guangzhou? What are the 5 characteristics of the Java language?
If you want to learn Java well, you must first understand the programming features of the Java language. Java has many programming features. Today, Qianfeng Guangzhou Java Training Xiaobian will share the 5 most common Java language features.
- First of all, it is simple to understand the Java language
The syntax of the Java language is very close to the C and C++ languages, making it easy for most programmers to learn and use Java. Java, on the other hand, discards rarely used, hard-to-understand, and confusing features of C++, such as operator overloading, multiple inheritance, and automatic type casting. In particular, the Java language does not use pointers, and provides automatic garbage collection, so that programmers do not have to worry about memory management.
- The Java language is distributed
The Java language supports the development of Internet applications. There is a network application programming interface (Java net) in the basic Java application programming interface, which provides a class library for network application programming, including URL, URLConnection, Socket, ServerSocket and so on. Java's RMI (Remote Method Activation) mechanism is also an important means of developing distributed applications.
- The Java language is safe
Java is usually used in the network environment, for this, Java provides a security mechanism to prevent malicious code attacks. Qianfeng Guangzhou Java training instructor said that in addition to the many security features of the Java language, Java has a security mechanism (ClassLoader) for classes downloaded through the network, such as assigning different namespaces to prevent replacement of local classes with the same name. Section code inspection, and provides a security management mechanism (class SecurityManager) to allow Java applications to set security sentinels.
- The Java language is an object-oriented
The Java language provides primitives such as classes, interfaces, and inheritance. For the sake of simplicity, it only supports single inheritance between classes, but supports multiple inheritance between interfaces, and supports the implementation mechanism between classes and interfaces (the keyword is implements) . The Java training instructor said that the Java language fully supports dynamic binding, while the C++ language only uses dynamic binding for virtual functions. In short, the Java language is a pure object-oriented programming language.
- The Java language is robust
Java's strong type mechanism, exception handling, and automatic garbage collection are important guarantees for the robustness of Java programs. Discarding pointers is a sensible choice for Java. Java's security checking mechanism makes Java more robust.
There are many features and characteristics of the Java language, and the above is only a small part of it for your reference. If you want to learn Java well, you can come to Qianfeng Guangzhou Java Training Institute to learn systematically. Qianfeng Guangzhou Java training develops 6 major dimensional courses, covering microservice architecture + large, medium and Taiwan strategy, allowing you to fully master Java core technology, popular industry projects, multi-disciplinary joint projects, and cultivate your professional quality and post-employment development ability.
In addition to high-quality face-to-face teaching and a large number of practical project training, Qianfeng Guangzhou Java Training Institute also arranges mock interviews for students on the eve of graduation, so that students can give full play to their own advantages in the real interview process and become a Java Development Engineer.
