Answers
None of the mentioned facts about assignment operators is incorrect.
- To give a variable a certain value, assignment operators are employed in a program. A variable serves as the assignment operator's left side operand, and a value serves as its right side operand. The variable on the left must have the same data type as the value on the right side so that the compiler can avoid raising an error. Assignment operators can be used only with numeric and character data types. Assignment operators are more efficiently implemented by java run-time system than their equivalent long forms.
- A specific example of the assignment operator where the source that is there on the right-hand side and destination which is there on the left-hand side are of the same class type is the copy assignment operator. It is one of the special member functions, thus if the programmer doesn't declare one, the compiler will create a default version of it. By default, each member is copied by its own copy assignment operator in a copy operation that is done memberwise. Assignment operators run faster than their equivalent long forms.
Hence, none of the mentioned facts about assignment operators is incorrect.

Answer:
The statement "Assignment operators can be used only with numeric and character data type" is incorrect.
Explanation:
Assignment operators are used to assign a value to a variable. They are used to update the value of a variable with a new value. They are widely used in programming, such as in Java, to simplify the process of updating variables. However, they can be used with any type of data, not just numeric and character data types as mentioned in the question, they can also be used with data types like Booleans, Arrays, and objects. The performance of assignment operators versus their equivalent long forms also depends on the specific implementation and usage, and cannot be generalized as saying that assignment operators are more efficiently implemented by java run-time system or run faster than their equivalent long forms. It is best to test and profile the specific use case to determine the best method for a particular implementation.
