StringBuilder objects can be used instead of String objects when the string data is not constant, the string data size may grow, or the programs frequently perform string concatenation. StringBuilder allows for more efficient manipulation of strings as it does not create new string objects each time a modification is made. Therefore, all of the above options are valid reasons to use StringBuilder over String.
