How to check out Prevision revision

[Tech Cool]

Hello Group,
                I am facing problem to check out previous revision. I am using following API method and it gives error

updateClient.doCheckout(url, destPath, SVNRevision.PREVIOUS , PREVIOUS , isRecursive);

regards,

Hello,

SVNRevision.PREVIOUS makes no sense for doCheckout method - there is no
revision number to base upon at the moment of checkout. If you'd like to
check out revision HEAD-1, then you may get HEAD revision first:

SVNInfo info = SVNWCClient.doInfo(URL, SVNRevision.HEAD, SVNRevision.HEAD);
SVNRevision latestRev = info.getRevision();
SVNRevision previous;
if (latestRev.getNumber() > 0) {
     previous = SVNRevision.create(latestRev.getNumber() - 1);
} else {
     previous = latestRev; // in case latest repo revision is 0.
}

Then call doCheckout with "previous" revision.
