Java Method parameter passing

1. The concept of the method body. First, the class, and then the class to generate the object, which is also called an instance

2. A class consists of two components: properties and methods. Attributes are generally represented by nouns, and methods are generally represented by verbs.

3. If a Java source defines more than one class, then there can be only one public in that class.

4. When passing parameters of a method in Java, whether the pass is a native data type or a reference data type, the parameter is passed uniformly as a value, and there is no concept of passing the reference in Java
