Welcome to the palace of Java
java language?
Java is the general term for Java object-oriented programming language and Java platform launched by Sun Microsystems in May 1995. It was jointly developed by James Gosling and his colleagues and officially launched in 1995.
Java is widely used in enterprise software development, Android mobile development, big data cloud computing and other fields, involving almost all IT
industries. The development history and characteristics of Java will be introduced later
Is java difficult?
This must be a question that the brothers who are new to java want to know, then you can come to find out with the famous morning!
First of all, the Java language is difficult:
the syntax of the Java language is very close to the C language and C++ language, making it easy for most programmers to learn and use. On the other hand, Java discards those features that are rarely used, difficult to understand, and confusing in C++, such as operator overloading, multiple inheritance, and automatic type conversion. In particular, the Java language does not use pointers, but references. And provides automatic waste collection, so that programmers do not have to worry about memory management.
Java is object-oriented: The
Java language provides object-oriented features such as classes, interfaces, and inheritance. For simplicity, only single inheritance between classes is supported, but multiple inheritance between interfaces is supported, and classes and interfaces are supported. Implementation mechanism (keyword is implements). Java language fully supports dynamic binding, while C++ language only uses dynamic binding for virtual functions. In short, the Java language is a pure object-oriented programming language.
Java is distributed:
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
