Question

In Java, find if the first character in a string is upper case without using regular expressions.

Answer 1

Make sure you first check for null and empty and ten converts existing string to upper. Use S.O.P if want to see outputs otherwise boolean like Rabiz did.

 public static void main(String[] args)
 {
     System.out.println("Enter name");
     Scanner kb = new Scanner (System.in);
     String text =  kb.next();

     if ( null == text || text.isEmpty())
     {
         System.out.println("Text empty");
     }
     else if (text.charAt(0) == (text.toUpperCase().charAt(0)))
     {
         System.out.println("First letter in word "+ text + " is upper case");
     }
  }
