This looks like a classic string manipulation exercise—a great way to practice working with the substring method in Java. cbtfturbo login ID and password

public class Solution {

public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    String S = in.next();
    int start = in.nextInt();
    int end = in.nextInt();
    in.close();
    System.out.println(S.substring(start,end));

Java logic for substring

  Scanner in = new Scanner(System.in);
        String S = in.next();
        int start = in.nextInt();
        int end = in.nextInt();
        String str = S.substring(start,end);
        System.out.println(str);
