9. The Catch or Specify Requirement

• Each Java program must follow this rule: the code will not compile unless the Catch or Specify requirement is honored. When a block of code can throw an exception, such block of code must be

  • (a) wrapped by a try statement that catches exceptions and handles them in the corresponding catch blocks (catch)

    
        try {
            //a block of code that can throw an exception
        } catch ( ExceptionType ex ) {
            //...
        }
    
    

  • (b) enclosed in a method with the throws clause (specify)

    
        public void saveFile() throws IOException {
            //a block of code that can throw an exception
        }///saveFile
