What institutions are good for java training?

1. Look at the teaching course

Learning Java technology, the most important thing is to keep pace with the times and master the technical points to meet the employment needs of enterprises at present. If you want to know whether the courses offered by a training institution are novel or not, you can also go to official website of that institution to learn about the syllabus of the subject you want to study.

See how the learning roadmap is arranged, whether there is a system from zero to one, whether there is a ratio of intensive training and practical operation, and the actual projects are as many as possible. Because enterprises have higher requirements for the technical ability and practical ability of Java practitioners.

2. Look at the teachers.

Because the technical knowledge of Java development is very professional, blind learning is easy to go wrong. On the contrary, standing on the shoulders of giants under the guidance of lecturers often gets twice the result with half the effort. After all, in this era, as long as you communicate with others more, you can get more and more valuable information. Beginners should never build a car behind closed doors.

See word of mouth

The industry has a good reputation, and students are more recognized by training institutions. Such institutions are student-centered, which is the proper attitude of education.

4. Look at the employment situation

At present, training institutions that aim at students' employment are the most important. You should know that employment is also the embodiment of teaching achievements. Without good teaching guarantee, good employment cannot be achieved.

5. Free live audition

Audition is to better feel the courses, teaching styles and class atmosphere of training institutions, and to further understand whether all aspects of training institutions meet their own needs through communication with class students.

language feature

1. Simple

Java looks a lot like C++, but in order to make the language small and familiar, designers have removed many available features in C++ language, which are rarely used by ordinary programmers. For example, Java does not support go to statements, but provides break and continue statements and exception handling.

Java also eliminates the operator overloading and multiple inheritance characteristics of C++, and does not use the main file, thus eliminating the preprocessor. Because Java has no structure, arrays and strings are objects, so pointers are not needed. Java can automatically handle object references and indirect references, and realize the automatic collection of useless units, so that users don't have to worry about storage management and can spend more time and energy on research and development.

2. Object-oriented

Java is an object-oriented language. For programmers, this means focusing on data and the methods of manipulating data, rather than thinking strictly according to the process. In an object-oriented system, a class is a collection of data and methods for manipulating data.

Data and methods together describe the state and behavior of an object. Every object is an encapsulation of its state and behavior. Classes are arranged according to a certain system and hierarchy, so that subclasses can inherit the behavior of superclasses. There is a root class in this class hierarchy, which is a class with general behavior. Java programs are organized by classes.
