What is Java?
什么是Java?
Before we start speaking about Java’s advantages, students must have a clear understanding of what Java is. First of all, it is a general-purpose programming language, which is very similar to Python and JavaScript. It is an object-oriented coding language. It has a lot of similarities to C++, C#. Java is not only a programming language; it is a specialized platform, which can run on a different machine that has installed the Java Virtual Machine (JVM).
在我们开始谈论Java的优势之前,学生必须对Java是什么有一个清晰的了解。 首先,它是一种通用的编程语言,与Python和JavaScript非常相似。 它是一种面向对象的编码语言。 它与C ++,C#有很多相似之处。 Java不仅是一种编程语言; 它是一个专用平台,可以在安装了Java虚拟机(JVM)的其他计算机上运行。
What are the benefits of using Java over similar programming languages?
与类似的编程语言相比,使用Java有什么好处?
Java is the top coding language, which has many significant advantages. It is a high-level computing platform, which was developed by Sun Microsystems in 1995. Java has been updated many times starting with Java SE 8.0 and finishing with the latest version , released in March 2019. It gained great popularity thanks to multiple configurations. Nowadays, the importance of web/mobile-based applications is growing. Java is considered the best foundation for creating networked applications. It is useful for scripting, web-based content, enterprise software, games, and mobile applications.
Java是最重要的编码语言,它具有许多重要的优点。 这是一个高级计算平台,由Sun Microsystems于1995年开发。从Java SE 8.0开始,到2019年3月发布的最新版本 ,对进行了多次更新。配置。 如今,基于Web /移动应用程序的重要性日益提高。 Java被认为是创建网络应用程序的最佳基础。 它对于脚本,基于Web的内容,企业软件,游戏和移动应用程序很有用。
Applications designed on Java
用Java设计的应用程序
Many enterprises use Java. For example, Oracle, around three billion devices, run various applications, which are created on the Java development platform. Let’s have a look at some applications which were designed using Java:
许多企业使用Java。 例如,Oracle大约有30亿台设备运行各种在Java开发平台上创建的应用程序。 让我们看一下使用Java设计的一些应用程序:
What are the main advantages of using Java?
使用Java的主要优点是什么?
Java offers programmers high functionality and portability. Any program, which is written in Java platform, can run across all kind of systems: desktops, mobiles, embedded systems.
Java为程序员提供了高功能性和可移植性。 用Java平台编写的任何程序都可以在所有类型的系统上运行:台式机,移动设备,嵌入式系统。
Simplicity in the learning process
简单的学习过程
If you compare Java and C++, Java is much simpler to learn and understand. Using Java, you will learn the essential concepts and syntax faster.
如果将Java和C ++进行比较,则Java的学习和理解要简单得多。 使用Java,您将更快地学习基本概念和语法。
Forget about pointers
忘记指针
Java does not use pointers at all because they are confusing even for experienced programmers. That is why students should not use pointers without in-depth knowledge and experience.
Java根本不使用指针,因为即使对于有经验的程序员而言,它们也会造成混淆。 这就是为什么学生不应在没有深入知识和经验的情况下使用指针。
Independent platform
独立平台
Java has a core philosophy to write one program and run it on any device. It is one of the most significant advantages of Java that its compiled code can run on different platforms without the need for recompilation.
Java的核心理念是编写一个程序并在任何设备上运行。 Java的最重要优点之一是其编译后的代码可以在不同的平台上运行,而无需重新编译。
Garbage Cleaner
垃圾清洁剂
Java offers its users professional automatic memory management to prevent any memory leakage in created applications.
Java为用户提供专业的自动内存管理,以防止创建的应用程序中的任何内存泄漏。
JIT Compiler
JIT编译器
By using JIT compiler, programmers can execute Java bytes codes much faster. The process of execution of C and C++ is slower compared to Java.
通过使用JIT编译器,程序员可以更快地执行Java字节代码。 与Java相比,C和C ++的执行过程更慢。
Multi-threaded applications
多线程应用
Users of Java can make multi-threaded applications. Concurrency is one of the critical features of the Java platform. By using multi-threading, you will use the same memory location.
Java用户可以制作多线程应用程序。 并发是Java平台的关键功能之一。 通过使用多线程,您将使用相同的内存位置。
Conclusion
结论
