How to fill out week 2 using bufferedreader

How to fill out week 2 using BufferedReader:

First, import the BufferedReader class by adding the following line at the top of your Java program:

import java.io.BufferedReader;

Create an instance of the BufferedReader class by initializing it with a FileReader object. You can create a FileReader object by passing the filename or the file object to its constructor. For example:

BufferedReader reader = new BufferedReader(new FileReader("week2.txt"));

Use a try-catch block to handle any potential exceptions while reading the file. The most common exception that can occur is the FileNotFoundException, which is thrown if the specified file does not exist. For example:

try {

BufferedReader reader = new BufferedReader(new FileReader("week2.txt"));

// Rest of the code for reading the file

} catch (FileNotFoundException e) {

printStackTrace();

1. Use the readLine() method of the BufferedReader class to read each line of the file. The readLine() method returns a String containing the contents of the current line, and it automatically moves the cursor to the next line. Store the returned value in a variable to process or display it. For example:

String line;

while ((line = reader.readLine()) != null) {

// Process or display the line

Close the BufferedReader object after you finish reading the file to release any system resources. Use the close() method of the BufferedReader class to do this. For example:

reader.close();
