(Process a string) Write a program that prompts the user to enter a string and displays its length and its first character.

Enter a string:Does quantum determinacy have anything to with whether human cognition is deterministic?
The string is of length 88 and the first character is D

import java.util.Scanner;
class StringLength{
   public static void main (String args[]){
       Scanner input = new Scanner(System.in);
       System.out.println("Enter a string:");
       String ans = input.nextLine();
       System.out.println("The string is of length " + ans.length() + " and the first character is " + ans.substring(0, 1));

import java.util.Scanner;

class StringLength {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        // It seems like we shouldn't print a newline after Enter a string:
        // Try this and let me know. If it didn't work, we will try something else
        System.out.print("Enter a string:");
        String ans = input.nextLine();
        System.out.println("The string is of length " + ans.length() + " and the first character is " + ans.charAt(0));
    }
}
