How is the method substring() different from subSequence() in String class?

substring() returns a string while subSequence() returns a CharSequence
There's no difference
subSequence() is deprecated
substring() allows for regular expression patterns

The correct answer is: substring() returns a string while subSequence() returns a CharSequence

The method substring() returns a modified copy of the original string, while subSequence() returns a portion of the original string without modifying it. This allows for easier manipulation of strings without affecting the original. Option B is incorrect because there is a clear difference between the two methods. Option C is incorrect because subSequence() is not deprecated, but it may be less commonly used compared to substring(). Option D is incorrect because substring() does not specifically allow for regular expression patterns, although it can be used with them.
