I'm a beginner learning to program in Java. I have written a program that reads words from a file and prints them with spaces in-between in addition to as they exist in the file. When I run my program I get an error denoting an "exception in thread main".
Any help would be appreciated!
Thank You!

String filePath = "/Users/cameronburgess/Programming/I:O/words.txt";
String word = "";
int cv = 0;
String spacedWord = "";

BufferedReader readBot = new BufferedReader(new FileReader (filePath));
//user facing
System.out.println("This program will read from a File at :" + filePath);
System.out.println();
while (readBot.readLine() != null) {
word = readBot.readLine();
//spliter
while (word.length() != cv) {
spacedWord = spacedWord + " " + word.charAt(cv);
cv = cv + 1;
}
System.out.println(word + " OR " + spacedWord);
}
}
}
This program will read from a File at :/Users/cameronburgess/Programming/I:O/words.txt

Have a try to make some change for the while-loop,
You need to reset the value to cv =0; spacedWord="";
when you are trying to split the word.
like,
while ((word=readBot.readLine()) != null) {
//spliter
cv =0;
spacedWord="";
while ( cv <word.length()) {
spacedWord = spacedWord + " " + word.charAt(cv);
cv = cv + 1;
}
System.out.println(word + " OR " + spacedWord);
}
You will get the result as follows:
This program will read from a File at :TEST.txt
