Java comparing string to regex - while loop

Question

I want the user to enter a string and if the string does not match my regex expression then I want a message to be outputted and the user to enter a value again.

The problem is even when the string matches the regex it is treating it as if it does not match.

My regex: This should equal - Name, Name

[[A-Z][a-zA-Z]*,\s[A-Z][a-zA-Z]*]

My while loop:

  System.out.println("Enter the student's name in the following format - surname, forename: ");  studentName = input.next();
  while (!studentName.equals("[[A-Z][a-zA-Z]*,\\s[A-Z][a-zA-Z]*]")) {
    System.out.println("try again");
    studentName = input.next();
  }

Answer 1

The equals methods checks for string equivalence, not for matching regular expressions.

Just replace equals with matches. You should also remove the outer square brackets.

Answer 2

Could it be that your regexp is wrong?

test.matches("[A-Z][a-zA-Z]*,\\s[A-Z][a-zA-Z]*")

works fine for me.
