To ensure the uniqueness of each Java package name, in the latest Java programming specification, the programmer is required to add a unique prefix before the name of the package that is defined by itself. Since domain names on the Internet are not repeated, programmers generally use their domain names on the Internet as their own unique prefix for their own packages. For example: net.sinodata.javagroup Nomenclature of the 1.2 class Class names must begin with uppercase letters, and other characters in the words are lower case letters; 1) if the class name is made up of multiple words, the initial letters of each word should be capitalized, such as TestPage; 2) if the class name contains short words, each letter of the word should be capitalized, such as: XMLExample; Since classes are designed to represent objects, you should try to choose nouns when naming classes. Such as: Circle 1.3 nomenclature The first word of the methods name should begin with a lower case letter, and the latter will begin with a capital letter. For example: sendMessge 1.4 naming constants The names of constants should be capitalized and indicate the full meaning of the constant. If a constant name is made up of multiple words, it should be underlined to separate the words. For example: MAX_VALUE The naming methods for constants, at any time, encourage the use of constants instead of numbers and fixed strings. Constants can be concentrated at the beginning of the program, defined in part, or within a wider scope 1.5 parameter naming The naming conventions for parameter naming conventions and methods are the same, and in order to avoid confusion when readi
