Java File Reading: Creating Song Objects from Text

First, we'll create a Song class to store our music data.The Song class has three private fields: title and artist as Strings, and year as an integer. We also include a constructor and getter methods.To read files in Java, we need to import several classes from the java.io package.Our song data will be stored in a text file. Let's look at the expected format.The file structure follows a specific pattern. Each line represents one song, with values separated by commas.To read the file, we'll use the Scanner class inside a try-catch block to handle potential file not found errors.The Scanner class provides several useful features for reading and parsing our text file.When working with files, it's crucial to follow proper error handling practices.When specifying file paths, there are several important considerations to keep in mind.Now that we have our Song class and file reading setup ready, we can move on to parsing the data.Now that we have our file open, we'll read and process each line to create Song objects.We use Scanner's hasNextLine and nextLine methods to read the file line by line.The while loop continues until we've processed every line in the file.For each line, we split it into parts using the comma as a delimiter. We also verify that we have exactly three parts: title, artist, and year.Let's see how a line gets split into its components.We need robust error handling to deal with potential issues like invalid year formats.Here's how we handle valid and invalid year formats. Valid years are converted to integers, while invalid formats throw exceptions that we catch and handle.Finally, once we've validated all the data, we can create a new Song object.The Song object encapsulates our parsed and validated data in a structured format.To store our song collection, we'll use an ArrayList of Song objects.We'll use a try-with-resources block to safely manage our file resources while adding songs to the collection.As we read each song from the file, it gets added to our ArrayList. Here's what our collection might look like.We can perform various operations on our song collection.Here's a method to display all songs in our collection.We can also create a method to search for songs by title.When we search for a song, the method returns the matching Song object if found.It's important to handle cases where a song isn't found in the collection.
