I suggest you use readLine
and split
...
public static void main(String[] args) throws FileNotFoundException {
String line;
int x=0;
String [] cName = new String [100];
String [] cMascot = new String [100];
String [] cAlias = new String [100];
try (BufferedReader input = new BufferedReader(new FileStreamReader("test.txt"))) {
while ((line = input.readLine())!=null) {
cName[x] = line.split(",")[0];
cMascot[x] = line.split(",")[1];
cAlias[x] = line.split(",")[2];
x++;
}
}
}
