java complete Read a .csv file

To read a .csv file in Java, you can use the following steps:

1. Create a new FileReader object to read the file, passing the file name or path as a string parameter.
2. Create a new BufferedReader object, passing the FileReader object as a parameter.
3. Use the readLine method of the BufferedReader object to read each line of the file.
4. Split each line by the delimiter (usually a comma) using the split method of the String class.
5. Parse the values as needed and store them in a data structure or object.

Here is an example code snippet that demonstrates how to read a .csv file in Java:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class ReadCSVFile {
    public static void main(String[] args) {
        String csvFile = "data.csv";
        String line = "";
        String delimiter = ",";

        try (BufferedReader br = new BufferedReader(new FileReader(csvFile))) {
            while ((line = br.readLine()) != null) {
                String[] values = line.split(delimiter);
                // Do something with the values
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

In this example, the code reads a file named "data.csv" and splits each line by a comma delimiter. You can modify the code to handle different delimiters or to parse the values in a different way depending on your specific use case.
