Answer 1

The option -Xlint can be used to enable or disable warnings. By saying -Xlint:unchecked, you enable all detailed warnings about unchecked or unsafe operations. Instead of just getting a general warning that your program contains them, you'll get a detailed list of parts of your code that contains unsafe operations.
