D Compilation Fails

ANS:A - 1

Initially this looks like a question about the logical and logical shortcut operators '|' and '||' but on closer inspection it should be noticed that the name of the boolean method in this code is 'catch'. 'catch' is a reserved keyword in the Java language and cannot be used as a method name. Hence Compilation will fail.
