java中文件拷贝用流的方式
如果是同一机器上的文件拷贝可以用
File.rename()方法
public static void main(String[] args) throws IOException {
//set timer
Timer timer = new Timer();
long timeIterval = Long.valueOf(args[2]).longValue();
//System.out.println("test iterval" + timeIterval);
//timeInterval = args[3];
if (args[1] != null && args[1].length() != 0) {
if (args[0] != null && args[0].length() != 0) {
File inputFile = new File(args[0]);
if (inputFile.exists()) {
RunTimer runTimer = new RunTimer(args[0], args[1]);
timer.scheduleAtFixedRate(runTimer, 500, timeIterval);
} else {
System.out.println("file not existed");
}
}
}
}
}class RunTimer extends TimerTask {
int i = 0; String inputFileName = ""; String outputFileName = ""; /**
* @param string
*/
public RunTimer(String inputDir, String outPutDir) {
inputFileName = inputDir;
outputFileName = outPutDir;
// TODO Auto-generated constructor stub
