Answer:
False. A non void method must return something.
Explanation:
No, a non-void method has return statement in it and it returns a value based on the return type in the method declaration and the implementation of that method. Every non - void method has to return a value depending on its declaration. A non void method should have a return statement in it. As it is a non - void method and has return statement in it, it returns a value based on the implementation of that method. If a void method contains return statement in it, the method exits.
Answer:
The attack is known as SQI Injection attack.
Explanation:
SQI injection usually exploit some security lapse in an application software for it to be able to work. It usually attack websites and mostly known as attack vector but may equally attack any type of SQL database of a company. These attacks allow attackers to steal and use identity, tamper with existing data on a system or website of the company or allow the complete disclosure of all data on the system. SQL Injection can also destroy the data or make it otherwise unavailable. Most importantly, it can become administrators of the database server or even cause reconciliation issues for such company transactions (e.g banks) such as voiding transactions or changing balances.
