usedelimiterでcsvなどの区切り文字を指定することができる
以下の例は文字列を直接指定している
通常はFileInputStreamを使用してファイル読み込みとする

public class Outer {
    public static void main(String[] args) {
        Scanner sc = new Scanner("A B C");
        sc.useDelimiter(" ");
        try(sc) {
            while(sc.hasNext()) {
                System.out.println(sc.next());
            }
        }
    }
