Public static void main (String [] args) {System. out. println ("enter a value and press enter to end:"); then SC = new then (System. in); SC. useDelimiter ("\ n"); while (SC. hasNext () {String s = SC. next (); System. out. println ("Get value:" + s );}}

1. encapsulate the system. in input stream with the callback class

2. SC. userDelimiter ("\ n"); set the end of the input, and press enter to end.

3. Use SC. hasNext () to determine whether there is any content. If yes, use SC. next () to retrieve it.
