Having a hard time today String[i]->char

[Anthony Smith]

I cant my java book, and I only find something on the web....

String pwd = "test";
for (int i=0; i!=pwd.length(); i++)
      {
         if (Character.isLetter(pwd[i]))
            //do Something
         ;
      }

I dont understand why that does not work

for(int i=0;i<pwd.length();i++)>
      {
         if (Character.isLetter(pwd.charAt(i)))
            //do Something

I think your problem is "!=". The for loop is not running because the conditional is failing. Try this instead:

for (int i=0; i < pwd.length(); i++)
