Answer:
Explanation:
The following modified code correctly uses recurssion to reverse the string that was passed as a parameter to the reverseString method. A test output using the runner class can be seen in the attached image below.
import java.util.Scanner;
class U10_L2_Activity_One {
public static String reverseString(String str) {
if (str.isEmpty()) {
return str;
}
return reverseString(str.substring(1)) + str.charAt(0);
}
}
class runner_U10_L2_Activity_One
{
public static void main(String[] args)
{
System.out.println("Enter string:");
Scanner scan = new Scanner(System.in);
String s = scan.nextLine();
System.out.println("Reversed String: " + U10_L2_Activity_One.reverseString(s));
}
}
