Re: Good practice or not to close the file before System.exit(1)?

  One single call of ?System.exit? is justified for this purpose at
  the very end of ?main?:

public static void main( final java.lang.String args )
{ ... System.exit( returnCode ); }

  . The above code assumes that no more exception is active at
  this point. For example:

public static void main( final java.lang.String args )
{ int returnCode = 2; /* "2" indicates internal failure to set
  "returnCode" properly to some other value as intended below. */
  try { ... returnCode = ... ... }
  catch( final java.lang.Exception exception )
  { ... returnCode = ... ... }
  catch( ... even catch some other Throwables? ... )
  { ... returnCode = ... ... }
  System.exit( returnCode ); }
