What is the method for reading the content of a file line by line in Java?

Java offers several methods for reading the contents of a file line by line. Here are some commonly used methods:

1. Using the readLine() method of the BufferedReader class:
2. Attempt to read the contents of the file using BufferedReader, and process each line until the end. If an IOException occurs, print the stack trace.
3. Utilize the nextLine() method of the Scanner class.
4. Attempt to scan the contents of a file using a scanner object, processing each line. If the file is not found, print the exception.
5. Utilizing the lines() method of the Files class and stream operations:
6. Attempt to read the file’s lines and process each line individually, catching and printing out any IOException that may occur.

These methods can all read file contents line by line and perform corresponding operations on each line. The specific method you choose depends on your needs and personal preferences.
