searching a text file for a specific word

[mbonfyre]

I am writing a program that will read a text file and calculate number of words/characters etc. That bit works fine, but I am struggling on how to find a specific word(in this case 'The' - I also need it to be able to ignore case)

each time I search for ' the ' (leading and follwing space) I get an error 'unclosed character literal'

Please suggest where I am going wrong (I'm a beginner, so please go easy on the techical talk!)

 (I haven't included keyboard3.java or text file)

for (int i = 0;i < CurrentString.length();i++)
{if(CurrentString.charAt(i) == ' ')
{numberofCharacters++;}}

This is surely not what you want.


This is too much code for me to look all the way through. Check the reference of String for functions you might find helpful.
And be careful: 's' is a character, "s" is a string. 'the' is nothing. The compiler might eat it and make a UNICODE character from it, but it's not the string "the" you want.

thanks for your reply. I think that I understand what you are saying - I'll go away and play with my code a bit more
