Answer:
import java.util.Scanner; //to take input from user
public class MaximumCharacter
{
char ch='A';//set initially A which is smallest char
//more than one arguments are required to find max character
char maxCharacter(String line, int len, int counter)
{
if(counter==len) //all characters are compared
return ch;
else
{
if(ch < line.charAt(counter)) //compare ch with each character of input
{
ch = line.charAt(counter); //update value of ch
}
counter++;//update counter to check next character
return maxCharacter(line, len, counter); //recursive call with new value of counter
}
}
public static void main(String arga[]) //main method to control the program
{
MaximumCharacter obj = new MaximumCharacter(); //crating object of class.
Scanner IN = new Scanner(System.in); //objct of scanner class to take input
System.out.print(System.lineSeparator() + "Enter a word to find max character: ");
String input = IN.nextLine(); //take user input
char c = obj.maxCharacter(input, input.length(),0); //call function to find max character
System.out.println("'" + input + "' Max Character = " + c); //print max character
}
}
