Question
Which among the following methods is used to reverse the sequence of characters in a StringBuilder object?
a) backwards()
b) invert()
c) reverse()
d) flip()
Solution
To determine which method is used to reverse the sequence of characters in a StringBuilder
object, we can analyze the given options:
- backwards(): This is not a standard method in the
StringBuilder
class in Java. - invert(): This method does not exist in the
StringBuilder
class. - reverse(): This is a well-known method in the
StringBuilder
class that reverses the characters in the object. - flip(): There is no
flip()
method in theStringBuilder
class.
Conclusion
The correct answer is c) reverse(). This method effectively reverses the order of the characters in a StringBuilder
instance.
