Parse the local method to map the data types at the Java layer, and map the data types at the java layer.Preface The Java language defines different data types, such as basic types int and double, and all classes parent class objects. These are Java-level types, the processi

Most of the programming languages that most people learn systematically are the differences between value types and reference types, one of the first points learned in the learning process of these languages. Let's look at the differences between basic data types (Primitive Types) and reference
