Question

Hello,

Here is the program I'm trying to work on:

(Finding the number of uppercase letters in a string) Write a program that passes a string to the main method and displays the number of uppercase letters in a string.

Here is the code I have so far:

public class CountUppercase {


public static void main(String[] args) {


int count = 0;
String str = args[0];
for(int i=0;i<str.length();i++)
if(str.charAt(i)>64 && str.charAt(i)<91)
count++;

System.out.println("total upper characters in string" + str + "are" + count);
}
}

I'm getting the following errors in NetBeans:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at countuppercase.CountUppercase.main(CountUppercase.java:16)
Java Result: 1

Where am I going wrong?
