import java.util.*;

class App {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter a String: ");

String string = in.nextLine().toLowerCase();

System.out.print("Enter character to find: ");

String characterFind = in.nextLine().toLowerCase();

int index = string.indexOf(characterFind);

System.out.print("Index Position: ");

while (index >= 0) {

System.out.print(index + " ");

index = string.indexOf(characterFind, index + 1);

}

in.close();

}

}

Do this coding without using characterFind

Answer 1

import java.util.ArrayList;
import java.util.Scanner;

public class App{
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.println("Enter a String");
        String line = in.nextLine().toLowerCase();
        System.out.print("Enter character to find: ");
        char toFind = in.nextLine().toLowerCase().toCharArray()[0];
        ArrayList<Integer> indexes = new ArrayList<>();
        for (int i = 0; i < line.length(); i = index + 1) {
            int index = line.indexOf(toFind, i);
            if (index == -1) {
                break;
            }
            indexes.add(index);
        }
        System.out.print("Index Position: ");
        for (Integer index : indexes) {
            System.out.print(index + " ");
        }
        System.out.println();
    }
}
