我有以下数据的输入流:
---------------------------------------------
manil@manil-ubvm:~$ db2level
DB21085I Instance "manil" uses "64" bits and DB2 code release "SQL10010" with
level identifier "0201010E".
Informational tokens are "DB2 v10.1.0.0", "s120403", "LINUXAMD64101", and Fix
Pack "0".
Product is installed at "/home/manil/sqllib".
---------------------------------------------
从上面我需要v10.1.0.0
存储在一个字符串变量中。
如何使用java正则表达式做到这一点?
