Expert Solution & Answer
![Check Mark](/static/check-mark.png)
Explanation of Solution
“throw” an exception:
- To “throw” an exception means to generate an exception object.
- When an exception occurs in the method, an object is created by the method which in turn send to the runtime system.
- This created object is called exception object which holds the information about the error.
- The information includes its type and the state of the program when the error occurred.
- Thus, creating an exception object and giving it to the runtime system is called throwing an exception.
Explanation for incorrect options:
Built:
The term “built” does not comes under the concept of exception handling.
Hence, the option “A” is wrong.
Caught:
The term “caught” is used to represent error which is thrown.
Hence, the option “C” is wrong.
Killed:
The term “killed” does not comes under the concept of exception handling.
Hence, the option “D” is wrong.

If it is negative throw an exception and indicate the number is negative otherwise take the squire root of the number. Use exception handling to control the flow of the code.
