What is the Scanner
method to get a char
returned by the keyboard in Java.
like nextLine()
for String
, nextInt()
for int
, etc.
To get a char
from a Scanner
, you can use the findInLine
method.
Scanner sc = new Scanner("abc");
char ch = sc.findInLine(".").charAt(0);
System.out.println(ch); // prints "a"
System.out.println(sc.next()); // prints "bc"
If you need a bunch of char
from a Scanner
, then it may be more convenient to (perhaps temporarily) change the delimiter to the empty string. This will make next()
returns a length-1 string every time.
Scanner sc = new Scanner("abc");
sc.useDelimiter("");
while (sc.hasNext()) {
System.out.println(sc.next());
} // prints "a", "b", "c"
