Throwable and Errors

/*Abnormal system:----------| Throwable the superclass of an exception or error class--------------| Error error errors are generally used for JVM or hardware-initiated problems, so we do not normally use code to handle errors. --------------| Exception exceptions need to be handled by code.    How to distinguish between errors and exceptions: If the program has an unhealthy message, if the class name of the unhealthy information ends with an error, then it must be a mistake. If it ends in exception, it's definitely an exception. */classDemo9 { Public Static voidMain (string[] args) {//Java Virtual machines can only manage 64m of memory by default.         byte[] buf =New byte[1024*1024]; System.out.println ("Hello world!"); }}
