Why is java a website? Isn't java a programming language? What software can you make?

Java is divided into three directions, j2se is aimed at windows applications, jsme is aimed at mobile devices such as mobile phones, such as java you often see on mobile phones, j2ee is aimed at websites, j2se contains relatively basic knowledge, which is the basis for learning other directions, and because the WINDOWS program Java is not beautiful to do, it is not as simple as Microsoft's. Therefore, j2se is less used in desktop applications, j2me, and some mobile devices need embedded development languages. C++ and C have great advantages in these languages, so j2me is less, while j2ee has great advantages on the website, which is open source and free, and many components are relatively safer than Microsoft, so it is generally j2ee, and the basic knowledge is based on those of J2se interviewed, which is only possible if the basic knowledge is solid.
