Final answer:
In a try/catch statement, you specify the exception class in the catch block to define what type of exception it handles. For instance, 'catch (IO Exception e)' handles an IO Exception that may occur within the try block, and multiple catch blocks can be used for different exceptions.
Step-by-step explanation:
At the start of a catch block in a try/catch statement, you code the name of the exception class that defines the type of exception that the block is intended to catch. The catch block is then used to handle the specific exception if it occurs. For example, in Java, you might have a catch block that looks like this:
try {
// Code that may throw an exception
} catch (IO Exception e) {
// Handle an IO Exception here
}
In this case, the catch block is set up to handle an IO Exception. If an exception of this type is thrown within the try block, the catch block will execute, and the given code will address the exception accordingly. Each catch block can handle only one type of exception, but you can have multiple catch blocks for different types of exceptions.
