编写一个程序，分别使用字节流和字符流拷贝一个文本文件

以下是使用Java代码实现的示例：

使用字节流拷贝：

import java.io.*;

public class ByteStreamExample {
    public static void main(String[] args) {
        try (FileInputStream in = new FileInputStream("source.txt");
             FileOutputStream out = new FileOutputStream("destination.txt")) {
            int c;
            while ((c = in.read()) != -1) {
                out.write(c);
            }
        } catch (IOException e) {
            System.out.println("I/O Error: " + e);
        }
    }
}

使用字符流拷贝：

import java.io.*;

public class CharacterStreamExample {
    public static void main(String[] args) {
        try (BufferedReader in = new BufferedReader(new FileReader("source.txt"));
             BufferedWriter out = new BufferedWriter(new FileWriter("destination.txt"))) {
            int c;
            while ((c = in.read()) != -1) {
                out.write(c);
            }
        } catch (IOException e) {
            System.out.println("I/O Error: " + e);
        }
    }
}
