复制代码 代码如下:

try {

File inputFile = new File(args[0]);

if (!inputFile.exists()) {

System.out.println("源文件不存在，程序终止");

System.exit(1);

}

File outputFile = new File(args[1]);

InputStream in = new FileInputStream(inputFile);

OutputStream out = new FileOutputStream(outputFile);

byte date[] = new byte[1024];

int temp = 0;

while ((temp = in.read(date)) != -1) {

out.write(date);

}

in.close();

out.close();

} catch (FileNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block
