Have you been writing a lot of code following the Mute-Design-Pattern™ lately? E.g.
try {
complex();
logic();
here();
}
catch (Exception ignore) {
// Will never happen hehe
System.exit(-1);
}There’s an easier way with Java 8!
Just add this very useful tool to your Utilities or Helper class:
public class Helper {
// 18395 lines of other code here
@FunctionalInterface
interface CheckedRunnable {
void run() throws Throwable;
}
public static void mute(CheckedRunnable r) {
try {
r.run();
}
catch (Throwable ignore) {
// OK, better stay safe
ignore.printStackTrace();
}
}
// 37831 lines of other code here
}Now you can wrap all your logic in this nice little wrapper:
mute(() -> {
complex();
logic();
here();
});Done!
Even better, in some cases, you can use method references
try (Connection con = ...;
PreparedStatement stmt = ...) {
mute(stmt::executeUpdate);
