Java正則表達式最大,最小匹配


最大匹配模式 X?      X, once or not at all X*         X, zero or more times X+         X, one or more times X{n}         X, exactly n times X{n,}         X, at least n times X{n,m}         X, at least n but not more than m times 最小匹配模式  X??         X, once or not at all X*?         X, zero or more times X+?         X, one or more times X{n}?         X, exactly n times X{n,}?            X, at least n times X{n,m}?         X, at least n but not more than m times
正則表達式寫過不少,javascript貌似默認爲最小匹配的。一直不知道JAVA正則的最小匹配須要在後面加個?號。這裏給本身作一下筆記。
