Answer 1

Correct Answer - Option 3 : The catch block

Concept:

An exception is an unexpected event which occurs during run time which disrupts the normal flow of execution. Example: division by zero.

There are two blocks in this: try and catch block.

Explanation:

try block:

It contains set of statements where an exception can occur. It is always followed by a catch block.

catch block:

In this block, exceptions are handled. Additional information sent when an exception is thrown is placed in this block. A single try block can have multiple catch blocks. Throw keyword is used to transfer control from try block to catch block.

syntax:

try

{

// statement that causes exception

}

catch

{

//statements that handle exception

}
