How To Create A Second Scanner To Get Each Token Separated By Commas Top 5 Latest Posts

To create a second scanner that gets each token separated by commas, you can use the Scanner class in Java and set the delimiter to a comma.

Here’s an example code snippet:

java
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        String input = "apple,banana,orange";
        
        // create the first scanner to read the input string
        Scanner scanner1 = new Scanner(input);
        
        // create the second scanner to read each token separated by commas
        scanner1.useDelimiter(",");
        while (scanner1.hasNext()) {
            String token = scanner1.next();
            System.out.println("Token: " + token);
        }
        
        // close the scanners
        scanner1.close();
    }
}

In the code above, we first create a Scanner object scanner1 to read the input string “apple,banana,orange”. We then set the delimiter of scanner1 to a comma using the useDelimiter method. This means that scanner1 will read each token separated by commas.

We then loop through the tokens using the hasNext and next methods of scanner1. For each token, we print it to the console.

Finally, we close the scanners using the close method to release the resources used by them.

Note that you can replace the input variable with any string that contains tokens separated by commas.
