I need a clear explanation of this, even though I read this link on differences but no clear clarity. So can anyone explain to me on this in short with code?

As answered here, you might want to consider the second approach when the required resource is expensive to get.
// Always get heavy resource
getResource(resourceId).orElse(getHeavyResource());
// Get heavy resource when required.
getResource(resourceId).orElseGet(() -> getHeavyResource())
