Explanation of Solution
Difference between the “StringBuffer” and “StringBuilder” class:
| “StringBuffer” class | “StringBuilder” class |
| This class is thread safe that is many thread can’t access concurrently. | This class is not thread safe that is many thread can access concurrently. |
| Its methods are synchronized. | Its methods are not synchronized. |
| Performance is low in this class because, the operation of this class is slower than “StringBuilder” class. | Performance is high in this class because, the operation of this class is faster. |
| It is less efficient. | It is more efficient. |
Example for “StringBuffer”:
//Define "exampleTest1" class
class exampleTest1
{
//Define main function
public static void main(String[] args)
{
//Create an object "b" with parameter "Java"
StringBuffer b = new StringBuffer("Java");
/* Append "
b...

Construct a relational database schema from the ER diagram. Your set of schemas should include primary-key and foreign-key constraints and you should ensure there are no redundant schemas. has_model model modelID name vehicle has_vehicle VIN dealer_ID brand name has_available_option has_option has_dealer options options_ID specification dealer dealer ID name customer_ID owned_by customer customer ID namearrow_forward
