CSV File Reader Java Program

Reads the CSV file and returns each row as line and column values are separated with ' ' single space.

Let us consider test.csv file contains the below rows.

This java program parses the CSV file and provides the customized string content for each csv file lines.

import java.io.*;

public class CSVReaderTest {

	public static void readCSVFile(String csvFile, String delimiter) {
		try {
			File file = new File(csvFile);
			BufferedReader br = new BufferedReader(new FileReader(file));

			String line = "";

			String[] columnsStr;
			while ((line = br.readLine()) != null) {
				if(line.indexOf("id")>=0){
					continue;
				}
				columnsStr = line.split(delimiter);
				for (int i=0;i<columnsStr.length;i++){
					System.out.print(columnsStr[i] + " ");
				}
				System.out.println();
			}
			br.close();

		} catch (IOException ex) {
			System.out.println("IOException: "+ex.toString());
		}

	}

	public static void main(String[] args) {
		// csv file to read
		String csvFile = "d:/test.csv";
		String delim = ",";
		CSVReaderTest.readCSVFile(csvFile, delim);
	}

}
