Types of `Exception`

Here are two of the rules about how try/catch semantics try/catch blocks work:

The first catch block to match the type of Exception thrown gets control.

The most specific Exception types should appear first in the structure, followed by the more general Exception types.

To make full sense of these rules you need to know more about Exception types. Inspect the above hierarchy diagram of Exception.

An ArithmeticException is thrown for some types of arithmetic problems, such as when a division by integer zero is attempted. (However, not all arithmetic problems cause an ArithmeticException.)

Potential Gotcha!

In arranging the try blocks, a child class should appear before any of its ancestors. If class A is not an ancestor or descendant of class B, then it doesn't matter which appears first.

QUESTION 10:

You have a try block that might throw an ArithmeticException or some type of RunTimeException . Put these exceptions in the correct order in the catch blocks:

try
{
  // statements which might throw an ArithmeticException
  // or some type of RunTimeException
}

catch (  ex )
{
  // statements to handle this
  // type of exception
}

catch (  ex  )
{
  // statements to handle this
  // type of exception
}
 
// Statements following the structure
