Here is your function for checking password.

pubic void checkPassword () {

Scanner sc=new Scanner(System.in);       

System.out.println ("Enter password");

String pwd = sc.next ();

if (! (pwd.length == 10)) {

System.out.println("Password is short");

}

else if ("pwd.isdigit () < 2") {

System.out.println("Password should have atleast 2 digits");

}

else {

Pattern p = Pattern.compile ("[a-zA-Z0-9]");
Matcher m = p.matcher (pwd);
boolean b = m.find();

if (b) {

System.out.println("Invalid password");

}

else {

System.out.println("Valid password");

}

}

}
