java代码编写的30条建议经验技巧（30 tips and techniques for Java code） (1) the first letter of the class name should be capitalized. The initial letters of fields, methods, and objects (handles) should be lowercase. For all identifiers, consisting of all the words should be close together, and the middle capitalize the first letter of the word such as: ThisIsAClassName thisIsMethodOrFieldName if the definition of a constant initialization of the characters, all types of letters in uppercase static final identifier. This will indicate that they belong to the compile time constant. The Java package (Package) is a special case: they are all lowercase letters, even if the middle word is the same. For domain name extensions, names such as com, org, net, or edu should all be lowercase (which is also one of the differences between Java 1.1 and Java 1.2). (2) to create a class for general use, take the classic form and include definitions of the following elements: equals (), hashCode (), toString (), clone () (implement, Cloneable), implement, Serializable (3) for each class that you create, consider putting in a main () that contains the code used to test that class. To use a class in a project, we dont have to delete the test code. If any changes are made, the test can be easily returned. These code can also be used as an example of how to use the class. (4) the method should be designed as a brief and functional unit to describe and implement a discontinuous class interface section. Ideally, the approach should be brief and to the point. If the length is large, you may consider splitting it into shorter ways in some way. This is also convenient for reuse of class code (sometimes the methods must be very large, but they should only do the same thing). (5) to design a class, consider yourself as a client programmer (the use of the class should be very clear). Then, think of people who are in charge of the code and consider what types of changes are possible, and think about ways to mak
