Two ways that Java unexpectedly shuts down resources

Try-catch-finally commonly used to determine if the stream is empty when the exception is closed

 Public classCloseableutils { Public Static voidcloseable (closeable ... closeio) { for(closeable Clo:closeio) {if(clo!=NULL) {                Try{clo.close (); } Catch(IOException e) {System.out.println (Dateutils.getnowtime ()+clo.getclass (). GetName () + "Off exception occurred" +e); }            }        }    }}

try-with-resources , which automatically closes the resources in parentheses without manually adding code

Attention:
    1. Resource must inherit from java.lang.AutoCloseable    2. Definitions and assignments must all be done in a try

Try NULL ;) {    new fileoutputstream ( ")")    ; Catch (IOException e) {        e.printstacktrace ();}
