Comparing characters

Question

I'm trying to make a program that will have the user enter a string of code, and then compare the first and last characters of the string to each other
     String text=reader.readLine("Enter string of text ");
          System.out.println(text.length());
          int numsave=text.length();
          int savechar1=text.charAt(1);
          System.out.println(savechar1); 
          int savechar2=text.charAt(numsave);
          System.out.println(savechar2);The thought behind the length statement would be to have it check how long it is, and then since it would be the length, it would be the index for the last character as well, but apparently that doesn't fly in java because it gives me and error on that line when I compile it.

Answer 1

it checks the first character with
charAt(1), which spits out a number, whereas its
looking for actual characters when using endsWithLook at where you assign the value of savechar1. Is there anything in your code that tells the program you want it to make savechar1 an int? The program will make the type of savechar1 to be exactly what you tell it to be.
Edit: I guess that's not what you were worried about. However, you would have found debugging to be much easier if you could see the actual charcter returned by charAt(1), instead of just the int representation
As for using "endsWith", if you take a look at the charAt(int i) method in String, you'll see that it tells you the index numbers of the first and last characters in the String. What is the index number of the first character? (It's not 1 like you're saying above). What is the index number of the last character compared to String.length()?
Edit: Oh, I guess Gino went ahead and told you straight out what the indexes should be.
