Regular expression for detecting round brackets

Question

I have a large array with string. Now, I need to use the string in the array to form patterns. However for the string with round brackets, the constructed patterns don\'t work.

Answer 1

Because in line String text = "Student (male): John"; does not match with regex student \(male\)\:\s\w+

Replace input text with text = "student (male): John"; or first phrase strings to phrases[0] = "Student (male)";
