void whateverMethod() { } } This approach is advocated by effective Java author Josh Bloch, which not only avoids multi-threaded synchronization problems, but also prevents deserialization from recreating new objects, which can be a very strong barrier. The thread safety and serialization issues for enumerations are described in detail in the thread safety and serialization issues of enumeration types----enumerations in the depth analysis of Java,

It is more concise, automatically supports serialization mechanisms, and absolutely prevents multiple instantiations.This approach is advocated by effective Java author

Ucwords: Capitalize the first letter of each word in the string. return value: String Function type: Data processing Description: This function makes it possible for database queries (query) to run smoothly by using the string, quotation marks, and quotes that need to be processed by the database. The characters that will be changed include single quotes ('), double quotes ("), backslash backslash (\), and null character NUL (

Exception and error difference error and Exception Learn the difference between the exception and the error, and know what to do when you intercept an exception. by Josh Street Many programmers do not realize that there is a difference between an error and an exception, and that this distinction has important implications for how you manipulate your code when a problem arises (see sidebar, " Profile Errors and exceptions"). As Mary Campione in the

Singleton class can also be actively used in other places to be loaded, so this time instantiating Instance is clearly not appropriate. This is a reasonable way to compare the third and fourth ways. Sixth (enum): Public enum Singleton {INSTANCE. public void Whatevermethod () {}} This is a way that effective Java author Josh Bloch advocated, not only to avoid multithreading synchronization problems, but also to prevent deserialization of new objects

differs from the third and fourth way (a very subtle difference): The third and fourth Way is if the singleton class is loaded, Then the instance will be instantiated (not reaching the lazy loading effect), and this way is that the singleton class is loaded and instance is not necessarily initialized. Because the Singletonholder class is not actively used, the load Singletonholder class is displayed only when the GetInstance method is called, thus instantiating the instance. Imagine if instanti
