Answer 1

public class MyClass {
      
    public static void main(String args[]) {
        float f = 13.6871f;
        
        String s = String.valueOf(f);
        
        int index_of_decimal_point = s.indexOf(".");
        String fraction_part = s.substring(index_of_decimal_point + 1);

        int len = fraction_part.length();
        String last_digit = fraction_part.substring(len - 1, len);     
        
        System.out.println(last_digit);
