double type

OBJECTIVE-C data types can be divided into: basic data types, object types, and ID types. The basic data types are: int, float, double, and char types. The object type is the type of pointer declared by a class or protocol, such as:

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.

In Java, string is the final class, which provides strings that cannot be modified, and string types are used frequently in projects, and the following are some common string data type conversions: String data types are converted to seven data

1. Integer type extension typeExtension types are the ability to increase the speed and space in which computers work with data, and the different types of functions on different systems.Portable Type header file:, C language creates more type names

A primitive type, or a built-in type, is a special type that differs from a class in Java. They are the most frequently used types in our programming. Java is a strongly typed language, and the first declaration of a variable must describe the data

1. In addition to the static and final methods in Java, all other methods are bound at run time. The private method is implicitly specified as final, so the final method is not bound at run time. When you override a static, final, or private method
