    Default Small Problem with my Code

    Hello, I have this code:

    import java.util.Scanner;

    public class Question1 {

    // public static char isConsecutive() {


    //}

    public static void main (String[] args) {
    Scanner reader = new Scanner(System.in);
    System.out.print("Enter something: ");
    String word=reader.next();

    // creating an array
    String[] ArrayKespass= word.split("");

    System.out.println();

    //place our letters in array, and print them
    for (int x=0; x<ArrayKespass.length; x++) {
    System.out.print(ArrayKespass[x] + " ");
    }

    // skip a line
    System.out.println();

    // convert our letters into characters
    for (int i=0; i<=ArrayKespass.length; i++) {
    char c=word.charAt(i);



    }
    }

    }



    It works, but when i execute it it gives me this in red:

    java.lang.StringIndexOutOfBoundsException: String index out of range: 13
    at java.lang.String.charAt(Unknown Source)
    at Question1.main(Question1.java:33)

    at java.lang.reflect.Method.invoke(Unknown Source)
    at edu.rice.cs.drjava.model.compiler.JavacCompiler.ru nCommand(JavacCompiler.java:272)

    Can someone please explain to me why? And what should I do to solve the problem?

    Please read the Announcement topic at the top of the sub-forum to learn how to post your code in code tags.

    Your error is caused by looping: i<=ArrayKespass.length, and you knew that. You did it right in the other loop but wrong here.
