Hi,

I've got some code like this in a try block:

==
BufferedReader input_file = new BufferedReader(new FileReader(input_fil=

ename));

String curr_line;
int line_length_ref, k;

for (int i = 1; (curr_line = input_file.readLine()) != null; i++) {
if (i == 1) {
line_length_ref = curr_line.length; // save the length o=

f the first line of the file

    }
    else {
         if (curr_line.length != line_length_ref) {
            System.err.println("Input file must contain same =

number of columns through rows.");

            System.exit(1);
         }
    }}

==

However, I'm getting

==
cannot find symbol
symbol : variable length
==
for the curr_line.length calls. But isn't a .length attribute defined
for every String object?

For String instances, length is a method, not a variable:
curr_line.length()
