Use

String s="[[Identity (philosophy)|unique identity]]";
String[] results = s.replaceAll("^\\Q[[\\E|]]$", "")    // Delete double brackets at start/end
      .replaceAll("\\s+\\(([^()]*)\\)","_$1")           // Replace spaces and parens with _
       .split("\\Q|\\E");                               // Split with pipe
System.out.println(results[0]);
System.out.println(results[1]);

Output:

Identity_philosophy
unique identity
