Analogy is a good way to learn a new language, and here we look at the data types of the C language in the Java language.The C language provides a rich data type, and the following chart is a good representation of all C language data types:It is

1.1 Data TypesData types in Java are divided into two types: basic data type and reference data type. As for the reference type, we will gradually understand it in the subsequent study, which is not covered here, and focuses on the basic data types.
