any character, not just. If you want to use. Cut string, you need to escape: \ \.; Where parentheses are used to represent groupings, and the latter \\1 represent the first group, if you want to use "first group number 1" instead of the mere number 1, you need to use \ \ To escape. Group: ((A) (B (C))), who is the first group, and who is the second group? start with the left parenthesis and start counting. Code:1 Private Static void GetDanCi2 () {2 String str= "[

Java Regular Expression: does not contain a rule string, java rule stringOverview For log analysis, you often need to deal with thousands of log entries. To find data in a specific mode in a large amount of data, you often need to write many complex regular expressions. For

For example, to count the workload of a Java programmer writing code in one day (for example, the number of lines of valid code, the number of blank lines, and the number of lines of comments), this tool may serve as a reference. Idea: because the content of each Java source file consists of Java statements, blank lines, and annotations (excluding annotations), w
