str.substring(1,word.length()).equals(word.substring(1,word.length()))
``` | Try using:
```
if (str.length() > 0 && str.substring(1).startsWith(word.substring(1))) {

for the conditional as it is much clearer. Also, tvanfosson and Darth Eru are correct that the first conditional with the exact match on the first character is extraneous. |
