Hi,

Following example is for reading text file line by line in Java using the stream api in Java 8.

package my.code;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

public class StreamReadFile {

    public static void main(String[] args) throws IOException {
        // File to read
        String fileName = "data.txt";
        // Read file with streams and print each line
        Files.lines(Paths.get(fileName)).forEachOrdered(System.out::println);

    }
}

Thanks
