💡 Hint

Common Mistakes

Forgetting to put the file name in quotes causes a compile error.

Using a wrong file name that does not exist.

The file path must be a string literal, so it needs to be in quotes.

2fill in blank

medium

Complete the code to read one line from the CSV file.

Selenium Java

String line = reader.[1]();

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using lowercase 'readline' causes a compile error.

Using 'nextLine' is a Scanner method, not BufferedReader.

The correct method to read a line from BufferedReader is readLine() with capital L.

3fill in blank

hard

Fix the error in splitting the CSV line into values.

Selenium Java

String[] values = line.[1](",");

Drag options to blanks, or click blank then click option'

Asplit

BsplitLine

Cdivide

Dseparate

💡 Hint

Common Mistakes

Using non-existent methods like 'splitLine' causes errors.

Trying to use 'divide' or 'separate' which are not string methods.

The split method splits a string by a delimiter and returns an array.

4fill in blank

hard

Fill both blanks to loop through CSV lines and print the first value.

Selenium Java

while (([1] = reader.readLine()) != null) {
    String[] values = [2].split(",");
    System.out.println(values[0]);
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using different variable names causes compile errors.

Using 'reader' or 'values' incorrectly in the split method.

The variable line stores each line read and is used to split into values.

5fill in blank

hard

Fill all three blanks to close the reader and handle exceptions.

Selenium Java

try {
    BufferedReader reader = new BufferedReader(new FileReader("data.csv"));
    String [1];
    while (([2] = reader.readLine()) != null) {
        String[] values = [3].split(",");
    }
    reader.close();
} catch (IOException e) {
    e.printStackTrace();
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using different variable names causes errors.

Trying to use 'reader' as the line variable.

The variable line is declared and used consistently to read and split lines.
