Features of the Java language

The popularity of the Java language, in addition to its ability to compile the applets embedded in HTML files, but also lies in the Java language itself object-oriented, simple, platform-independent, security, multithreading and other characteristics of the Java language structure and writing methods, similar to the C + + language, so learning the Java language, Not only to understand the characteristics of the Java language, but also to have a programming foundation and object-oriented concepts. The Java language features the following:

The Java language features one: simple, efficient

The Java language is similar to C + +, and if users understand C + + and object-oriented concepts, they can quickly write Java programs, and Java is different from the various methods offered by the C + + language, which provides only the basic method, which reduces the complexity of programming, such as removing the header file, Complex features such as pointer variables, structs, operator overloading, multiple inheritance, and so on. Although the Java language is simple and efficient, it can use an object-oriented approach to describe each user's actions.

Features of the Java language Two: object-oriented

Java language is a new object-oriented programming language, in addition to several basic data types, mostly similar to C + + objects and methods, most of the program code embodies the class mechanism, organized in the form of classes, the class to define the various behavior of the object. Java also supports class inheritance, which also reduces the complexity of programming.

The Java language features three: platform independence

The Java language compiles and generates byte codes (bytecode) that are independent of the computer's hardware structure, which are defined as not dependent on any hardware platform and operating system. When the Java program is running, it needs to be interpreted by an interpreter for the generated byte code. This demonstrates the Java language's platform-agnostic nature, allowing Java programs to run on any platform, such as MS-DOS, Windows,unix, and so on, so it is highly portable.

Features of the Java language four: interactive features

Java is an object-oriented network programming language, because it supports the TCP/IP protocol, allowing users to access various dynamic objects on the Internet through a browser. And the user can perform various actions interactively on the network, and the introduction of multithreading technology makes this interactive operation easier.

Features of the Java language five: multithreading mechanisms

The Java language supports multithreaded mechanisms, and multithreading allows Java programs to handle multiple tasks in parallel. A Java program can be designed to have multiple threads, such as having one thread responsible for retrieving, searching, and another thread interacting with the user, so that two threads execute in parallel. The multithreading mechanism makes it easy to implement interactive operations on the network.

Features of the Java language VI: Dynamic memory management mechanism

The Java language uses an automatic garbage collection mechanism for memory management. In the C + + language, programmers need to carefully handle the use of memory when writing programs, such as when a memory is quickly used, to be released in time for other programs to use, once memory management is improper, it is possible to cause memory space waste or program operation failure. The Java system includes an automated garbage collection program that automatically and securely reclaims memory blocks that are no longer in use, so programmers can program without worrying about memory management, making Java programs easier to write, and reducing the likelihood of errors in memory management.

Features of the Java language Seven: security

In such a distributed network environment like the Internet, security is a problem that cannot be neglected. The Java language introduces real-time memory allocation and layout in terms of security to prevent programmers from modifying the physical memory layout directly, and checking byte code through byte code validators to prevent network viruses and other illegal code intrusions. In addition, the Java language uses many object-oriented exception handling mechanisms, which are responsible for handling some abnormal events, such as Insufficient memory space, program exception abort, etc.

The above describes some of the main features of the Java language, in addition to its dynamic, class library rich, high performance and so on, which makes the Java language in all aspects of the mature and perfect, becoming popular among the general programming language.
