OCPJP7 Exception Handling

1. Closeable (Java 5) throws IOException
   
   AutoCloseable (Java 7) throws Exception


2. Closeable extends AutoCloseable.


3. try-with-resources : close when get out of the try block in reverse order.


4. If more than one exception is thrown in a try-with-resources block
   
   All later exception will be added as suppressed.


5. try {
   
   }catch(Exception 1 | Exception 2 e) {
   
   }
   
   There should be no subclass relationship between Exception 1 and Exception 2. Do not assign a new value to "e" in multi-catch.


6. If exception throws in catch block or finally block, no suppressions happen.
   
   The last exception thrown get sent to the caller.


7. If a method throws a exception in the declaration, it must be included in try catch block. Even if it is in the finally block.



8. Try-with-resource Object must not have close method if that Object is declared in Try block.
