If the object implements ASN1Choice the tag style will always be changed to explicit in accordance with the ASN.1 encoding rules.

public boolean isExplicit()
Note: if the object has been read from an input stream, the only time you can be sure if isExplicit is returning the true state of affairs is if it returns false. An implicitly tagged object may appear to be explicitly tagged, so you need to understand the context under which the reading was done as well, see getObject below.

Note: tagged objects are generally context dependent if you're trying to extract a tagged object you should be going via the appropriate getInstance method.
