string类中的matches方法:
public boolean matches(String regex) {
return Pattern.matches(regex, this);
}
思考题:
/* 需求:把一个字符串中的手机号码获取出来*/
public static void main(String[] args) {
//demo1();
String s = "我的手机是18988888888,我曾用过18987654321,还用过18812345678";
String regex = "1[3578]\\d{9}";
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(s);
/*boolean b1 = m.find();
System.out.println(b1);
System.out.println(m.group());
boolean b2 = m.find();
System.out.println(b2);
System.out.println(m.group());*/
while(m.find())
System.out.println(m.group());
