Simple usage sharing of scanner classes in Java _java

Copy Code code as follows:

public static void Main (string[] args) {
System.out.println ("Please enter a value, end by carriage return:");
Scanner sc = new Scanner (system.in);
Sc.usedelimiter ("\ n");
while (Sc.hasnext ()) {
String s = sc.next ();
System.out.println ("Get Value:" +s);
}
}

1. Encapsulate system.in input stream with scanner class

2.sc.userdelimiter ("\ n"); Sets the flag for the end of the input and ends with a carriage return.

3. Use Sc.hasnext () to determine whether there is content, and then use Sc.next () to remove
