Regular expression support also exists injava.lang.Stringthrough several methods that mimic the behavior ofjava.util.regex.Pattern. For convenience, key excerpts from their API are presented below. public boolean matches(String regex): Tells whether or not this string matches the given regular expres...
java与正则相关的工具主要在java.util.regex包中;此包中主要有两个类:Pattern、Matcher。 Pattern 声明:public final classPatternimplements java.io.Serializable Pattern类有final 修饰,可知他不能被子类继承。 含义:模式类,正则表达式的编译表示形式。 注意:此类的实例是不可变的,可供多个并发线程安全使用。 字段:...

java.util.regex是一个用正则表达式所订制的模式来对字符串进行匹配工作的类库包。它包括两个类:Pattern和Matcher Pattern 一个Pattern是一个正则表达式经编译后的表现模式。 Matcher 一个Matcher对象是一个状态机器,它依据Pattern对象做为匹配模式

java.util.regex 类Pattern public final classPattern extendsObject implementsSerializable 正则表达式的编译表示形式。 指定为字符串的正则表达式必须首先被编译为此类的实例。然后,可将得到的模式用于创建Matcher对象,依照正则表达式,该对象可以与任意字符序列匹配。执行匹配所涉及的所有状态都驻留在匹配器中,所以多个匹配器...
