Question

#Java

I am reading from the txt file

and I put everytihng inside of the String[], like that:

String[] values = str.split(", ");

But, now I have to retrieve the data from it one by one. How can I do it?

Here is the txt file:

OneTime, finish the project, 2020-10-15
Monthly, wash the car, 2020-11-10

Thanks!

Main.java :

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

/*
Java Program to read file and retrieve comma separated String 
*/
public class Main {
  public static void main(String[] args) throws Exception {
    /*
    Redaing file using BufferedReader 
    */
    BufferedReader br = new BufferedReader(new FileReader("file.txt"));
    String line = null; // local variable to hold each line (it will change in each loop iteration)

    // while loop execute until no more line available to read in file.
    while ((line = br.readLine()) != null) {
      String[] values = line.split(","); // String array to hold each comma (,) separated string
      
      /*
      follwing for each loop retrieve the data from values(String array) one by one
      */
      for (String str : values) {
        System.out.println(str); // print each retrieved value in a single line
      }
    }
    br.close(); // close the BufferedReader.
  }
}
