Program Plan Intro

Try and catch block:

Java virtual machine (JVM) searches to handle the error in “catch” clause at that time of exception in the program. So “try-catch” statements are used in order to handle those exceptions. The following are the main keywords used in exception handling.

• • “try” block: Try block contains the block of statements to monitor the exception and it thrown the exception. It is possible to have a “try” block inside another large “try” block and “catch” block.
• • “catch” block: Catch block catch exception thrown by the try block to handle it.

Syntax:

    try

    {

        // Try block statement

    }

  // Catch block

    catch(Excep1 exObj)

    {

        // Catch block statement

    }
