Java ดึง Text ในไฟล์ .txt มาแสดงใน Java Netbeans ทำอย่างไรครับ

// Open the file
FileInputStream fstream = new FileInputStream("textfile.txt");

// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));

String strLine;

//Read File Line By Line
while ((strLine = br.readLine()) != null)   {
  // Print the content on the console
  System.out.println (strLine);
}

//Close the input stream
in.close();
