How do I fix this error? The Coding Language is Java.

public class AppleOrange {

public static void main(String[] args) {

int x = Integer.valueOf(args[0]);

for (int i = 0; i <= x ; i++) {

if (i%3==0) {

System.out.print("apple");

}

else if (i%7==0) {

System.out.print("orange");

}

else if (i%3 == 0 || i%7 == 0) {

System.out.print("appleorange");

}

else {

System.out.print(i + " ");

}

}

}

}

Error:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 0 out of bounds for length 0 at AppleOrange.main(AppleOrange.java:5)
