Java™ How To Program (Early Objects), Tenth Edition

7.5.1 The try Statement

To handle an exception, place any code that might throw an exception in a try statement (lines 17–26). The try block (lines 17–20) contains the code that might throw an exception, and the catch block (lines 21–26) contains the code that handles the exception if one occurs. You can have many catch blocks to handle different types of exceptions that might be thrown in the corresponding try block. When line 19 correctly increments an element of the frequency array, lines 21–26 are ignored. The braces that delimit the bodies of the try and catch blocks are required.
