学习正则表达式

First described by German zoologist Friedrich Boie in 1826, (212) 555-1212， 232-515-1212和242 545 1262 String telephone = "[(]?[\\d]{3}[)-]?[\\s]?[\\d]{3}[\\s-]?[\\d]{4}"; Pattern p = Pattern.compile(generalWord); Matcher m = p.matcher(text1); while( m.find()) { System.out.println(m.group()); } 结果：(212) 555-1212， 232-515-1212和242 545 1262

以下简写：

String generalWord = "[A-Z]*[a-z]+";//全部单词 String generalWord0 = "\\b[A-Z]+[a-z]+";//大写字母开头的单词 String generalWord1 = "\\b[a-z]+";//小写字母开头的单词 String mutiWord = "[A-Z]+[a-z]+([A-Z]+[a-z]+)*";//多个单词组合的单词:appStore String cn_zh = "[\\u4e00-\\u9fa5]";//取出所有汉字
