Writing CSV Files in Java Using OpenCSV

In Java, there is no delegate library or API for writing or reading comma-separated value (csv) files, so a third-party API can be used to meet this requirement. The most popular third-party API is OpenCSV, which provides methods for handling CSV files such as reading csv files, writing csv files, parsing csv file values, mapping csv file values to java beans, and mapping java beans to csv files, etc.
