hint:
Kunin mo length ng input.

use charAt() and concat(). Gagamit ka din parseInt() jan.

import java.util.*;

class Spoonfed {
public static void main(String spoonfedIsReal[]) {
Scanner get = new Scanner(System.in);
int input = get.nextInt();
int minuend = input / 10;
int subtrahend = input % 10;
int difference = minuend - subtrahend;
System.out.println(difference);
}
}

Kung gusto mo makuha logic ng problem mo. Yung above code yung maganda pag-aralan.
Pwede mo rin diretsuhin:

import java.util.Scanner;

public class MP01 {
    
    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        
        int userInput;
        int output;
        
        System.out.print("Input: ");
        userInput = s.nextInt();
        output = (userInput/10) - (userInput%10);
        System.out.println("Result: " + output);
    }   
}
