I am getting a null value when im reading from my teachers. csv file. Column 1 which is att[0] works but att[1] returns 3 null values.
My csv looks like this: 1, Mr Murphy 2, Mr Davis 3, Ms Simpson Each on separate lines ie line 1 -> 1, Mr Murphy etc
Here is my code:
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
public class ReadCSV
{
public static void main(String[] args)
{
//Input file which needs to be parsed
String readTeachers = "teacher.csv";
BufferedReader fileReader = null;
//Delimiter used in CSV file
final String DELIMITER = ",";
try
{
String line = "";
//String line = inFile.readLine();
//Create the file reader
fileReader = new BufferedReader(new FileReader(readTeachers));
int count=0;
String[] att = new String[10];
//Read the file line by line
while ((line = fileReader.readLine()) != null)
{
//Get all tokens available in line
String[] tokens = line.split(DELIMITER);
int i=0;
count++;
for(String token : tokens)
{
att[i] = token;
i++;
//Print all tokens
// System.out.println(token);
System.out.println(att[1]);
break;
}
}
//System.out.println(count);
//System.out.println(att[1]);
}
catch (Exception e) {
e.printStackTrace();
}
finally
{
try {
fileReader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
Your issue here is that you have a break statement inside the for loop that exits the loop at the end of the first iteration. Therefore, you are only putting a value in the first index of your array. Take out that statement and it should be fine.
for(String token : tokens)
{
att[i] = token;
i++;
//Print all tokens
// System.out.println(token);
System.out.println(att[1]);
break; // <---- ***take this out***
