Detecting Capitalization

I have this program in my Java class that is due on Monday (Pig latin translator). There are many rules to this and I just kind of started but this is what I have so far:

Code:

---

import java.util.*;
public class IgpayAtinlay {
       
        public static void main(String []args){
               
                Scanner Keyboard = new Scanner(System.in);
               
               

                String current_word;
               
                System.out.print("English: ");
                String input = Keyboard.nextLine();
               
                String[] word = input.split(" ");
               
                for(int i=0; i<=input.length()-1; i++)
                {
                        current_word=word[i];
                        wordToPig(current_word);
                       
                       
                }

               
               
               
               
               
        }
       
        public static boolean isCapitalized (String word){
               
                [B]if(word.charAt(0)){[/B]
                        return true;
                       
                }
                else
                        return false;
               
        }
       
        public static String lowerCase(String word){
               
                word=word.toLowerCase();
                return word;
        }
       
       
       
       
        /*public static String upperCase(String word){
                String temp, new_word;
               
                temp=word.substring(1);
                temp=temp.toUpperCase();
               
                new_word=temp;
               
                for(int i=1; i<word.length(); i++){
                new_word=new_word+word[i];
               
               
                }
                */
       
        public static String wordToPig (String english){
               
                String copy, firstletter, fin;
               
                if(isCapitalized(english)==true){
                        lowerCase(english);
                        //upperCase(current_word);
                }
                firstletter = english.substring(0);
                copy = english.substring(1,english.length()-1 );
                fin = copy+firstletter+"ay";
                return fin;
               
               
               

               
               
       
               
        }
}

As you can see, the area that is bolded I need help with. I know with C++, you can easily just say if(char > 97 || char < 65) etc, you can figure out if its capital or not (because in C++ chars are secretly integers). However, I dont think this is the case in Java.

Any help would be appreciated.

You can test a char against 'a' for example (char > 'a'). chars can be treated as int in java
This kind of code: (char > 97) is poor because you have to look up the value of 97 to see what char it is.
Using a literal like 'Z' shows exactly what you are testing.

Thanks for the reply. However, that isn't what I am looking for. For example, if someone entered:

Daniel

I want to say: if(firstletter is capital)
so I started saying

if(word.charAt(0) > ???)
I don't know what the word is yet so I can't actually write the specific character.

Would this work?
if(word.charAt(0) > 'z')

Would ^^^^ that mean that the word's first index be a capital letter?

You should write a small program and try some different values to see what the results are.

Do you know whether 'a' is > or < 'A'?
Try this: System.out.println("'a' > 'A' = " + ('a' > 'A'));

I got:

'a' > 'A' = true

so I should write:

if(word.charAt(0) > 'z')
then its a capital, right?

Thank you for your help! I found out that this is the order:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwx yz

Therefore if(word.charAt(0) < 'a')

we know it is capital :)!
(Just for reference in case others stumble upon this thread)

Sometimes yes, sometimes no.
There are a lot of other character values that are less than 'a'.
The best test would be for the letter to be in the range from 'A' to 'Z'

Ok so how about

if(word.charAt(0) >= 'A' && word.charAt(0) <= 'Z')

:-)

That looks about right

What about something like:

Code:

---

  public static boolean isCapitalized (String word) {
        return Character.isUpperCase(word.charAt(0));
    }
