e1071. copying one file to another.txt

这里面包含了一百多个JAVA源文件

This example uses file streams to copy the contents of one file to another file. See e172 Copying One File to Another for an example that uses file channels. 
    // Copies src file to dst file.
    // If the dst file does not exist, it is created
    void copy(File src, File dst) throws IOException {
        InputStream in = new FileInputStream(src);
        OutputStream out = new FileOutputStream(dst);
    
        // Transfer bytes from in to out
        byte[] buf = new byte[1024];
        int len;
        while ((len = in.read(buf)) > 0) {
            out.write(buf, 0, len);
        }
        in.close();
        out.close();
    }
