public class DelimetersDemo {

public static void main(String[] args)

//The only delimiter for keyboard2 is ##.

System.out.println("Enter a line of text with two words:");
s1 = keyboard1.next( );
s2 = keyboard1.next( );
System.out.println("The two words are \"" + s1 +
"\" and \"" + s2 + "\"");

System.out.println("Enter a line of text with two words");
System.out.println("delimited by ##:");
s1 = keyboard2.next( );
s2 = keyboard2.next( );
System.out.println("The two words are \"" + s1 +
"\" and \"" + s2 + "\"");
}
}

Answer 2

A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace. keyboard2 is told to set the delimiter to ## which means each token has to be separated by a double #.
e.g. entering "hello world" (without the quotes) for keyboard1 will set s1="hello" and s2="world"
similarly, entering "hello##world" (without the quotes) for keyboard2 will s1="hello" and s2="world"
