Question

/* Method: findName() */
/**
 * Finds the name of the entry and sets it to the name variable.
 */
    private void findName(String line){
        end = line.indexOf(" ");
        name = line.substring(0,end);
    }

/* Method: findDecades() */
/**
 * Finds the name of the entry and sets it to the name variable.
 */
    private void findDecades(String line){
        for(int i = 0; i<NDECADES; i++){
            int start = end + 1;
            end = line.indexOf(" ",start);
            String decadeTemp = line.substring(start, end);
            data[i] = Integer.parseInt(decadeTemp);
        }
    }

Line looks like the following:

Sam 58 69 99 131 168 236 278 380 467 408 466

When I run the code the first method runs fine but then it throws an error exception when it reaches the line:

            String decadeTemp = line.substring(start, end);

edit:

the error that is throw is:

throw new StringIndexOutOfBoundsException(endIndex – beginIndex);

Answer 1

Problem solved NDECADES was one space too big.
