java正则表达式判断手机号、邮件、QQ格式校验

具体理解推荐

package test;
public class Expression {
	public static void main(String[] args) {
		System.out.println("手机号" + isPhone("18768668681"));
		System.out.println("随意" + isPhone("11168668681"));
		System.out.println("qq.com" + "t" + isEmail("318717611@qq.com"));
		System.out.println("163.com" + "t" + isEmail("fall123@163.com"));
		System.out.println("随意" + "t" + isEmail("fall"));
	}

	
	public static boolean isPhone(String phone) {
		boolean dophone = phone.matches("^1(3|4|5|7|8|9)\d{9}$");
		return dophone;
	}

	
	public static boolean isEmail(String email) {
		boolean doemail = email.matches("\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*");
		return doemail;
	}

	public static void checkQQ() {
		String qq = "374355539";
		// 检查号码和规则是否匹配,String类的方法matches
		boolean b = qq.matches("[1-9][0-9]{4,9}");
		System.out.println(b);
	}
