本文提供了一个使用Java语言读取文本文件的简单示例程序，通过使用File类和BufferedReader类来实现文件读取操作。

package HeadFirstJava;

import java.io.*;

class ReadAFile {
    public static void main(String[] args) {
        try {
            File myFile = new File("MyText.txt");
            FileReader fileReader = new FileReader(myFile);
            
            BufferedReader reader = new BufferedReader(fileReader);
            
            String line = null;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
            reader.close();
        } catch(Exception ex) {
            ex.printStackTrace();
        }
    }
}

Whose house is this?
I think I know.
River flows happily.
Sun shines brightly.
