Explore code examples for efficient file parsing and data extraction. --- CSV (Comma-Separated Values) files are a popular format for storing tabular data. In Java, reading a CSV file with a header involves a few steps, such as opening the file, parsing its contents, and extracting data. Let's explore a simple Java code example that demonstrates how to read a CSV file with a header. Java Code Example: [[See Video to Reveal this Text or Code Snippet]] Explanation: BufferedReader: We use the BufferedReader class to read the contents of the CSV file efficiently. Reading Header: The first line of the file contains the header. We read it and split it into an array of column names. Processing Data: After reading the header, we loop through the remaining lines and split each line into an array of values. Accessing Columns by Header: To make the code more readable and maintainable, we use the header to access specific columns by name. Helper Method (getIndex): This method helps in finding the index of a specific column in the header. Conclusion: Reading CSV files with headers in Java involves parsing the file, extracting column names, and processing the data accordingly. The provided code offers a straightforward way to achieve this, making it easier to work with CSV data in Java.
