I. Preface: Before writing this blog, we need to understand two concepts: local transaction and distributed transaction. Local transactions: Only a single data source, such as a single database, is processed. Distributed transactions: Handling a

one, set and array arrays , which can store basic data types, are a container for storing objects, but the lengths of the arrays are fixed and are not suitable for use when the number of objects is unknown. The length of the collection (which

Look at a program. String t = "a| | b| | c| | D "; string[] temp = t.split ("\\|\\|"); System.out.println (temp.length); Mainly is: "\\|\\|" stands for what meaning. The beginning is a bit of a monk, then carefully see understand, the original is
