Comparison of Commons CSV (SANDBOX) framework with other CSV processing libraries
Commons CSV (SANDBOX) is a Java library for processing the CSV (comma separation value) file.It provides a simple, flexible and efficient way to read and write into the CSV file.This article will be compared with other CSV processing libraries and provides some Java code examples.
1. Commons CSV (Sandbox) vs OpenCSV:
OpenCSV is another widely used CSV processing library, which also provides the function of reading and writing CSV files.However, compared to OpenCSV, Commons CSV (Sandbox) has the following advantages:
-Commons CSV (SANDBOX) supports CSV file specifications such as RFC 4180 and RFC 71111.
-Commons CSV (SANDBOX) provides richer options to analyze and write CSV files, such as custom separation symbols, reference characters, changing line characters, etc.
-Commons CSV (SANDBOX) reads CSV files through Iterator mode, which makes processing large CSV files more efficient.
The following is a sample code for analysis of CSV files using the Commons CSV (Sandbox):
import org.apache.commons.csv.CSVFormat;
import org.apache.commons.csv.CSVParser;
import org.apache.commons.csv.CSVRecord;
import java.io.File;
import java.io.IOException;
import java.nio.charset.StandardCharsets;
public class CsvParserExample {
public static void main(String[] args) {
try {
File csvFile = new File("path/to/csv/file.csv");
CSVParser csvParser = CSVParser.parse(csvFile, StandardCharsets.UTF_8, CSVFormat.DEFAULT);
for (CSVRecord csvRecord : csvParser) {
String column1 = csvRecord.get(0);
String column2 = csvRecord.get(1);
// Processing CSV record
}
csvParser.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
2. Commons CSV (Sandbox) vs Super CSV:
Super CSV is another popular CSV processing library, which provides advanced features such as converters and verifications.However, the Commons CSV (Sandbox) is different from Super CSV in the following aspects:
-Commons CSV (Sandbox) has better performance and smaller memory occupation, especially when processing large CSV files.
-Commons CSV (SandBox) provides a more intuitive and flexible API, which simplifies the reading and writing process of the CSV file.
-Commons CSV (SANDBOX) has high development activity, providing more timely bug repair and new functional development.
The following is a sample code written to the CSV file with the Commons CSV (SANDBOX):
import org.apache.commons.csv.CSVFormat;
import org.apache.commons.csv.CSVPrinter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.nio.charset.StandardCharsets;
public class CsvWriterExample {
public static void main(String[] args) {
try {
File csvFile = new File("path/to/csv/file.csv");
FileWriter fileWriter = new FileWriter(csvFile, StandardCharsets.UTF_8);
CSVPrinter csvPrinter = new CSVPrinter(fileWriter, CSVFormat.DEFAULT);
csvPrinter.printRecord("Column1", "Column2");
csvPrinter.printRecord("Value1", "Value2");
// Write more CSV records
csvPrinter.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
In summary, the Commons CSV (Sandbox) is a powerful CSV processing library that provides more intuitive, flexible and efficient ways to read and write CSV files than OpenCSV and Super CSV.From the perspective of performance or function, the Commons CSV (Sandbox) is an excellent choice for handling CSV files.
