http://www.runoob.com/regexp/regexp-syntax.html java正则表达式主要是关于java.util.regex中的两个类: 1.Pattern:正则表达式经过编译后的表现模式。 2.Matcher:一个Matcher对象是一个状态机,它依据Pattern对象做为匹配模式对字符串展开匹配检查。 两者的关系是,Matcher在Pattern给定的模式控制下进行字符串匹配工作...

java.util.regex 包主要包括以下三个类: Pattern 类: pattern 对象是一个正则表达式的编译表示。Pattern 类没有公共构造方法。要创建一个 Pattern 对象,你必须首先调用其公共静态编译方法,它返回一个 Pattern 对象。该方法接受一个正则表达式作为它的第一个参数。
