我試圖代碼,一個新的文件夾中或者不通過傳遞特定的時間戳通過javacode存在,但我沒有得到它..canü幫助...文件存在或不經過時間
String filePath = System.getProperty("user.dir");
//create a new file with Time Stamp
File file = new File(filePath + "\\" + filename+GetCurrentTimeStamp().replace(":","_").replace(".","_")+".txt");
try {
if (!file.exists()) {
file.createNewFile();
System.out.println("File is created; file name is " + file.getName());
} else {
System.out.println("File already exist");
}
} catch (IOException e) {
e.printStackTrace();
}
}
// Get current system time
public static String GetCurrentTimeStamp() {
SimpleDateFormat sdfDate = new SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss.SSS");// dd/MM/yyyy
Date now = new Date();
String strDate = sdfDate.format(now);
return strDate;
}
// Get Current Host Name
public static String GetCurrentTestHostName() throws UnknownHostException {
InetAddress localMachine = InetAddress.getLocalHost();
String hostName = localMachine.getHostName();
return hostName;
}
// Get Current User Name
public static String GetCurrentTestUserName() {
return System.getProperty("user.name");
我不知道你在描述什麼。另外,詳細說明「我沒有得到它」的含義。什麼是實際問題? – David
