Java正則表達式驗證至少6位表達式中至少包含數字大小寫字母中的一種

直接上代碼

public class TestRegex {

    public static void main(String[] args){


        String a = "^(?!^$)([a-zA-Z0-9]{6,})$";
        Pattern pattern2 = Pattern.compile(a);
        System.out.println("1111111："+pattern2.matcher("1111111").matches());

        System.out.println("aaaaaaa："+pattern2.matcher("aaaaaaa").matches());

        System.out.println("AAAAAAA："+pattern2.matcher("AAAAAAA").matches());

        System.out.println("1111AAA："+pattern2.matcher("1111AAA").matches());

        System.out.println("1111aaq："+pattern2.matcher("1111aaq").matches());

        System.out.println("1111Aaq："+pattern2.matcher("1111Aaq").matches());

        System.out.println("1111Aa!："+pattern2.matcher("1111Aa!").matches());

    }
}
