{
boolean doElse = true;
for (final Foo foo : this.getFoos()) {
// process the foo
doElse = false;
}
if (doElse) {
// There was not a single foo
}
}
// ----------------------------------------
// How it would be with for-else:
for (final Foo foo : this.getFoos()) {
// process the foo
} else {
// There was not a single foo
}
// -----------------------------------------
// Java 8 Stream API:
getFoos().stream().forEachElse(f -> f.process(), () -> System.out.println("No foo :-("));
