Read a file and Split using StringTokenizer in Java


In this program, we will take a look at how to read a file and split its contents using StringTokenizer Class in Java,

File Content:
Id, Name, Age, Gender
1, Sam, 22, Male
2, Rita, 32, Female
3, Alex, 21, Female
4, Kate, 22, Female
Program:
import java.io.*;
import java.util.StringTokenizer;


/**
 * Read a file and split lines 
 * using StringTokenizer
 */
public class StringTokenizerExample {

    public static void main(String[] args) throws IOException {
        
        File csvFile = new File("/Users/c2c/input-file.csv");

        try (BufferedReader br = new BufferedReader(new FileReader(csvFile))) {
            String line;
            while ((line = br.readLine()) != null) {

                StringTokenizer stringTokenizer = new StringTokenizer(line,",");

                while (stringTokenizer.hasMoreTokens()) {
                    //Split the line using stringTokenizer
                    System.out.println(stringTokenizer.nextToken().trim());
                }
            }
        }
    }
}
Output:
Id
Name
Age
