[Google Guava] string processing: Connector, splitter, character match

First, the connector "Joiner"

Second, the splitter "Splitter"

Three, character match "Charmatcher"

　　

Iv. Character Set "Charsets"

　　charsets: The six character sets that are guaranteed to support all Java platforms provide a constant reference. Try to use these constants instead of getting character set instances by name.

    Try {            byte[] bytes = Test.getbytes ("UTf-8");         Catch (unsupportedencodingexception e) {            e.printstacktrace ();        }

Change to the following expression:

byte [] bytes = Test.getbytes (charsets.utf_8);

is actually equivalent to:

byte [] bytes = Test.getbytes (Charset.forname ("UTF-8"));

V. Uppercase and lowercase format "Caseformat"

Caseformat is used to easily convert strings between various ASCII case specifications, such as the naming conventions for programming languages. Caseformat supports the following formats:

Format	Example
Lower_camel	Lowercamel
Lower_hyphen	Lower-hyphen
Lower_underscore	Lower_underscore
Upper_camel	Uppercamel
Upper_underscore	Upper_underscore

String Testcaseformat = CaseFormat.UPPER_UNDERSCORE.to (Caseformat.lower_camel, "constant_name");
