'Optional' can be replaced with sequence of 'if' statements

Reports Optional call chains that can be replaced with a sequence of if statements.

Example:

return Optional.ofNullable(name)
  .map(this::extractInitials)
  .map(initials -> initials.toUpperCase(Locale.ENGLISH))
  .orElseGet(this::getDefault);

After the quick-fix is applied:

if (name != null) {
  String initials = extractInitials(name);
  if (initials != null) return initials.toUpperCase(Locale.ENGLISH);
}
return getDefault();

java.util.Optional appeared in Java 8. This inspection can help to downgrade for backward compatibility with earlier Java versions.

New in 2020.2
