Question

I would like to create a regular expression pattern that would succeed in matching only if the pattern string not followed by any other string in the test string or input string ! Here is what i tried :

      Pattern p = Pattern.compile("google.com");//I want to know the right format

      String input1 = "mail.google.com";
      String input2 = "mail.google.com.co.uk";

      Matcher m1 = p.matcher(input1);
      Matcher m2 = p.matcher(input2);

      boolean found1 = m1.find();
      boolean found2 = m2.find();//This should be false because "google.com" is followed by ".co.uk" in input2 string

Any help would be appreciated!

Answer 1

You should use google\.com$. $ character matches the end of a line.

Pattern p = Pattern.compile("google\\.com$");//I want to know the right format

String input2 = "mail.google.com.co.uk";

Matcher m2 = p.matcher(input2);


boolean found2 = m2.find();
System.out.println(found2);

Output = false
