Yes.
When the "rats" is encountered,
hasNextInt()
returns false and the loop (and program) ends gracefully.
(The phrase "ends gracefully" is what programmers say when
a program ends without a crash accompanied by error messages.)
| Methods of Scanner | |
|---|---|
| HasNext Method | Reading Method |
| hasNext() | next() |
| hasNextDouble() | nextDouble() |
| hasNextFloat() | nextFloat() |
| hasNextInt() | nextInt() |
| hasNextLine() | nextLine() |
| hasNextLong() | nextLong() |
There are several hasNext methods and
corresponding next methods.
Usually your programs will use the methods for int and double.
The hasNext() and next() methods
work with tokens which are groups of characters
delimited (surrounded) by one or more spaces.
Does hasNext() consume any of the characters from the stream?
