在Java中，如何将两个独立的文件复制到两个独立的位置？

import java.io.*;

public class FileCopyExample {
    public static void main(String[] args) {
        // 源文件路径
        File sourceFile1 = new File("path/to/sourceFile1.txt");
        File sourceFile2 = new File("path/to/sourceFile2.txt");

        // 目标文件路径
        File targetFile1 = new File("path/to/targetFile1.txt");
        File targetFile2 = new File("path/to/targetFile2.txt");

        try {
            // 创建文件输入输出流
            FileInputStream fis1 = new FileInputStream(sourceFile1);
            FileInputStream fis2 = new FileInputStream(sourceFile2);
            FileOutputStream fos1 = new FileOutputStream(targetFile1);
            FileOutputStream fos2 = new FileOutputStream(targetFile2);

            // 创建缓冲字节流
            BufferedInputStream bis1 = new BufferedInputStream(fis1);
            BufferedInputStream bis2 = new BufferedInputStream(fis2);
            BufferedOutputStream bos1 = new BufferedOutputStream(fos1);
            BufferedOutputStream bos2 = new BufferedOutputStream(fos2);

            // 复制文件1
            int data1;
            while ((data1 = bis1.read()) != -1) {
                bos1.write(data1);
            }

            // 复制文件2
            int data2;
            while ((data2 = bis2.read()) != -1) {
                bos2.write(data2);
            }

            // 关闭流
            bis1.close();
            bis2.close();
            bos1.close();
            bos2.close();

            System.out.println("文件复制成功！");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
