Java Exception Trapping (try/catch/finally)

Languages Focus: Exception Trapping

A common usage of exception handling is to obtain and use resources in a "try-it" block, deal with any exceptions in an "exceptions" block, and release the resources in some kind of "final" block which executes whether or not any exceptions are trapped.

Java Exception Trapping

try {

  /* Risky code here. */

catch (SomeException) {        //one or more.

  /* Recovery here. */

finally {                      //0 or one.

  /* Do something. */
