Java One week learning sentiment

In the one by one school year, I studied C and Python in two languages, and in the sophomore semester, Java was a new programming language. Learn more about Java in terms of reading the textbook and guiding the instructor in class.

The first thing to feel is that Java has a pleasing syntax and easy-to-understand semantics. It has the following 11 points features. The first is simplicity, and Java's syntax is a "pure" version of the C + + syntax. It has no header file, pointer arithmetic, structure, union, operator overloading, virtual base class, etc. Another aspect of simplicity is the small. 2nd it focuses on the interface of data and objects, and the main difference between C + + is multiple inheritance. 3rd of its distribution, he had a rich example of libraries. 4th robustness. 5th security. The 6th architecture is neutral. 7th portability. The data type has a fixed size. The 8th explanatory type. 9th High Performance. Thanradioactive multithreading. The 11th dynamic nature.

Java is object-oriented, platform-independent, is now widely used in various fields, in the course of the teacher also talked about these, I think with interest to learn this subject will be easier to understand him. In learning Java, it is important to think that there is a certain C-language foundation. Java will be case-sensitive, when debugging the program, may be due to letters, spaces and other small errors debugging errors, in the future study to pay extra attention to do not make these careless mistakes. Through this semester of study, I believe that will have a thorough understanding of Java.
