Java programming skills
From the perspective of readers without programming experience, the Experts teach readers to learn Java
16-hour multimedia teaching video, efficient and intuitive
Cracking the difficulties and doubts that may arise when getting started with Java
It makes learning easier and easier.
Through a lot of metaphor, analogy, comparison, illustration and other explanations, the learning effect is good
Each Syntax of Java provides one or more examples.
A large number of Flowcharts are used to represent the execution process of the program, and a structure diagram is used to represent the internal state of the program.
At the end of each chapter, typical exercise questions are provided, allowing readers to exercise in time, consolidate and improve, and provide reference answers.
