TRY Statement (JVM COBOL)

The TRY block allows you to test a section of code for exceptions that may occur during its execution. The CATCH block must specify the type of exception you wish to handle if one should occur during the execution of the TRY block. The FINALLY block allows you to execute a section of code following the TRY block, whether or not an exception occurred.

Context:

    Procedure Division
        Statements

try-statement

Example of a local declaration of an exception

      *>   The example below shows that you can declare e at the point of use.
      *>   It is in scope until the end-try.
           try
               display "exception test"
           catch e as type Exception
               display e::Message
           end-try

Further Information

In the TRY statement, the:

TRY statement-block

specifies the section of code to be tested for exceptions that may occur during its execution

CATCH statement-block

specifies the type of exception to handle if an exception occurs during execution of the TRY block

FINALLY statement-block

specifies the section of code to execute following the TRY block, whether or not an exception occurred

Your program can raise an exception using the RAISE statement and pass this exception back to the caller. This is commonly referred to as "throwing an exception".
