String Manipulation...cont!

[Jim Hooper]

Mmmm...think I'm missing something here...my code is as follows

public static void main(String[] args)
{
String numword = args[0];
String output;
int i;
int i1;
int i2;

if (numword.charAt(0) = "1")
{.......

but will not accept numword.charAt(0). Error -
Java_4a.java:29: unexpected type
required: variable
found : value
if (numword.charAt(0) = "1")
^

Any help greatly appreciated!
Thanks again....

should be

if (numword.charAt(0) == '1')

notice the double == and the single quotes.


Personally I would add some checks to ensure that there is a string passed in and that it has a lenght of at least 1. Just good a good habit to be in.
