Java language is an object-oriented programming language suitable for what?

The Java language is an object-oriented programming language suitable for software development in a network environment.

Java is an object-oriented programming language. It not only absorbs the various advantages of the C language, but also abandons the concepts such as multiple inheritance and pointers that are difficult to understand in C. Therefore, the Java language is powerful and easy to use. Two characteristics. As a representative of static object-oriented programming languages, Java language perfectly implements object-oriented theory and allows programmers to perform complex programming with an elegant way of thinking.

Main features of Java language:

1. Cross-platform

The so-called cross-platform means that the software can run normally in any computer environment without being restricted by computer hardware and operating systems. This is the trend of software development and the goal pursued by programmers. The reason why I say this is because there are many types of computer hardware and different operating systems. Different users and companies have their own different computer environment preferences. In order for software to run normally in these different environments, it needs to be independent of these platforms.

In the Java language, the virtual machine that comes with Java has achieved cross-platform very well. The binary bytecode generated after Java source code is compiled is platform-independent but a machine code instruction that can be recognized by the Java virtual machine. The Java virtual machine provides a barrier from bytecode to the underlying hardware platform and operating system, making the Java language cross-platform.

2. Object-oriented

Object-oriented refers to using objects as the basic granularity, which includes properties and methods. The description of an object is expressed in terms of properties, and the object is manipulated by using methods. Object-oriented technology makes application development simple and easy to use, saving code. Java is an object-oriented language and inherits many object-oriented benefits, such as code expansion and code reuse.

3. Security

Security can be divided into four levels, namely language-level security, compile-time security, run-time security, and executable code security. Language-level security means that Java's data structures are complete objects, and these encapsulated data types are safe. The Java language and semantics must be checked during compilation to ensure that each variable corresponds to a corresponding value, and a Java class is generated after compilation. At runtime, Java classes need to be loaded by the class loader and verified by the bytecode verifier before they can be run. When a Java class is used on the network, its permissions are set to ensure the security of the users being accessed.
