Assign the size of userinput to stringsize. ex: if userinput is "hello", output is: size of userinput: 5

import java.util.Scanner;

public class StringSize {

  public static void main (String [] args) {

     Scanner scnr = new Scanner(System.in);

     String userInput;

     int stringSize;

     userInput = scnr.nextLine();

     /* Your solution goes here  */

     stringSize = userInput.length();

     System.out.println("Size of userInput: " + stringSize);

     return;

  }

}

Explanation:

stringSize = userInput.length();  //  userInput.length() will get the length of the string and  put in stringSize
