Question
Which of the following operators is used to generate instance of an exception which can be thrown using throw
?
Options
thrown
malloc
alloc
new
Solution
The correct answer is "new". This operator is used in many programming languages, like Java and C++, to create a new instance of a class or an exception that can be thrown using the "throw" keyword. Here are the steps to do it:
- Define the exception class if it's a custom exception. If it's a built-in exception, you can skip this step.
- Create a new instance of the exception using the "new" keyword followed by the constructor of the exception class.
- Use the "throw" keyword followed by the instance of the exception to throw it.
For example, in Java:
try {
throw new Exception("This is an exception");
} catch (Exception e) {
e.printStackTrace();
}
In this example, "new" is used to create a new instance of the Exception class, and "throw" is used to throw it.
