Java讀檔、寫檔

最少行數的寫檔：

private static void writeUsingFiles(String data) {
        try {
            Files.write(Paths.get("/Users/pankaj/files.txt"), data.getBytes());
        } catch (IOException e) {
            e.printStackTrace();
        }
}

最少行數的讀檔：

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

    public static void main(String[] args) throws IOException {
        String content = new String(Files.readAllBytes(Paths.get("duke.java")));
    }
