20 years old with 30 years of work experience.

A netizen suddenly found an advertisement on the platform saying that he wanted programmers Java, PHP, tpshpc++ front-end, Python. The important thing is that the following requirements are actually under 20 years old and have 30 years of programming experience, so he was teased by netizens.

Java is an object-oriented programming language, which not only absorbs the advantages of C++ language, but also abandons the concepts of multiple inheritance and pointers that are difficult to understand in C++, so Java language has two characteristics: powerful function and simple use. As the representative of static object-oriented programming language, Java language perfectly realizes the object-oriented theory and allows programmers to carry out complex programming in an elegant way of thinking.
