The Java basics mentioned here refer to the content that you should master most when learning Java. Basic skills required for desktop development, network development, web development, and enterprise-level development. It includes the following aspects: Basic Java syntax, Java object-oriented features, common functions, and common Java class libraries. About the Basic Java syntax, you should master the following aspects: n the general process of writing a Java application: including how to write a Java file, how to name a Java file, if you compile a Java file, how to run the expression of N information in a Java file: constant and variable, basic data type N representation of similar information: array n how to handle information in Java: Selection of various operations n execution process: if and switchn execution cycle: while loop and for loop N integration development environment n code debugging Java object-oriented features, should master the following content: N class and object n How to Write Class N inherit n interface n package common functions, should master the following content: N includes Exception Handling n multithreading N use third-party class library Java common class library, you should master the following content: N string and stringbuffer use N date and calander use N Date Format and Number Format n list and arraylist use N set and hashset use N map and hasnmap The use of N collections and arrays using N iterator, serializble, and comparatorn regular expressions is what I think of now. It may take a few weeks and I will modify them later. In the future, the basic part of Java will follow this idea. If not, please correct me. Next Lecture: What can Java do?
