The CSV stands for Comma-Separated Values. It is a simple file format which is used to store tabular data in simple text form, such as a spreadsheet or database. The files in the CSV format can be imported to and exported from programs (Microsoft Office and Excel) which store data in tables. The CSV file used a delimiter to identify and separate different data token in a file. The CSV file format is used when we move tabular data between programs that natively operate on incompatible formats. There are following ways to read CSV file in Java. The default separator of a CSV file is a comma (,).

There are following ways to print an array in Java:
The problem is that you’re using ints instead of intobjs where you want to pass things around by reference (& in c). In your main function, you should try declaring i and j as intobjs and your parameter for fun, k should also be an intobj.

Step 3: Now, save the file. Provide the file name CSVDemo and select CSV (Comma delimited) from the save as type menu. Now, click on the Save button.Using Notepad
Step 1: Open notepad.
Step 2: Write some data into file separated by comma (,). For example:
Vivek, Singh, 23, 9999999, Chandigarh
Step 3: Save the file with .csv extension.

Java Scanner class provide various methods by which we can read CSV file. The Scanner class provides a constructor that produces values scanned from the specified file. It breaks data into the token form. It uses a delimiter pattern which by default matches white space. The resulting tokens then converted into values of different types using the next() methods.
Exampleimport java.io.*;import java.util.Scanner;public class ReadCSVExample1{public static void main(String[] args) throws Exception{//parsing a CSV file into Scanner class constructorScanner sc = new Scanner(new File(’F:CSVDemo.csv’));sc.useDelimiter(’,’); //sets the delimiter patternwhile (sc.hasNext()) //returns a boolean value{System.out.print(sc.next()); //find and returns the next complete token from this scanner} sc.close(); //closes the scanner}}
Output:Java String.split() method
Java String.split() identifies the delimiter and split the rows into tokens.
Syntaxpublic String[] split(String regex)
The method parses a delimiting regular expression. The method returns an array of string computed by splitting this string around matches of the given regular expression.
Consider the string:
’this:is:a:table’RegexResult : {’this’, ’is’, ’a’, ’table’}
Example
In the following example, we use BufferedReader class which reads file line by line until the EOF (end of file) character is reached.import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException;public class ReadCSVExample2{public static void main(String[] args) {String line = ’;String splitBy = ’,’;try {//parsing a CSV file into BufferedReader class constructorBufferedReader br = new BufferedReader(new FileReader(’CSVDemo.csv’));while ((line = br.readLine()) != null) //returns a Boolean value{String[] employee = line.split(splitBy); // use comma as separatorSystem.out.println(’Employee [First Name=’ + employee[0] + ’, Last Name=’ + employee[1] + ’, Designation=’ + employee[2] + ’, Contact=’ + employee[3] + ’, Salary= ’ + employee[4] + ’, City= ’ + employee[5] +’]’);}} catch (IOException e) {e.printStackTrace();}}}
Output:Using OpenCSV API
OpenCSV is a third party API which provide standard libraries to read various versions of CSV file. The library provides better control to handle the CSV file. The library can also read TDF (Tab-Delimited File) file format.Features of OpenCSV
*Any number of values per line.
*Ignores commas in quoted elements.
*Handles entries that span multiple lines.
The CSVReader class is used to read a CSV file. The class provides CSVReader class constructor to parse a CSV file.
Syntaxpublic CSVReder(Reader reader, char separator)ORpublic CSVReder(Reader reader)
Parameters
reader: The reader to a CSV source.
separator: It is a delimiter which is used for separating entries.
Steps to read CSV file in eclipse:
Step 1: Create a class file with the name ReadCSVExample3 and write the following code.
Step 2: Create a lib folder in the project.
Step 3: Download opecsv-3.8.jar from
Step 4: Copy the opencsv-3.8.jar and paste into the lib folder.
Step 5: Now, run the program.
Exampleimport java.io.FileReader;import com.opencsv.CSVReader;public class ReadCSVExample3{ public static void main(String[] args){CSVReader reader = null;try{//parsing a CSV file into CSVReader class constructorreader = new CSVReader(new FileReader(’F:CSVDemo.csv’));String [] nextLine;//reads one line at a timewhile ((nextLine = reader.readNext()) != null){for(String token : nextLine){System.out.print(token);}System.out.print(’n’);}}catch (Exception e) {e.printStackTrace();}}}

Reading CSV file with a different separator
In the following CSV file, we have used semicolon (;) to separate tokens.
Exampleimport java.io.FileReader;import java.io.IOException;import com.opencsv.CSVReader;public class ReadCSVExample4 { public static void main(String[] args){CSVReader reader = null;try{reader = new CSVReader(new FileReader(’F:CSVDemo.csv’)); String [] nextLine;//read one line at a timewhile ((nextLine = reader.readNext()) != null){for(String token : nextLine){System.out.println(token);}System.out.print(’n’);}}catch (Exception e) {e.printStackTrace();}}}
