In java. Java. io. the StringTokenizer class can parse a single string. split in jdk1.4 can also parse a single string, but cannot parse the Reader stream, when parsing multiple characters, it cannot return a string that separates two strings. The following class is written to solve this problem. You can also prepare some basic parsing types, * and?
You can set multiple splits for resolution. The corresponding split string is returned during resolution.
Programs can run directly
