The program is executed for the second time. When a string value is given as an array value, then the second exception is generated, and the statement of the second catch block is executed. Example-3: Exception handling with try-catch-finally block The use of finally block with the try-...

that it reads values saved from variables that were in scope at the time the exception occurred—then uses what it learns to restore the Java program to a flow of normal behavior. For example, an exception handler might read a saved filename and promp the user to replace the missing file...
