Java reads the file, converts the string into a date type, and adds the date type to the

Recently always read the file with Java, found a way I personally feel better, now share to everyone

public static void Main (string[] args) throws Exception
{
FileInputStream f = new FileInputStream ("File path");
InputStreamReader FileInputStream = new InputStreamReader (f);
BufferedReader br = new BufferedReader (FileInputStream);
String str= "";
SimpleDateFormat SDF = new SimpleDateFormat ("Yyyy-mm-dd");

while ((Str=br.readline ())!=null) {
Date date = Sdf.parse (str); Convert a string into a date type
String bedate= Sdf.format (New Date (Date.gettime ()-7 * 24 * 60 * 60 * 1000)); Figure out the date seven days ago
System.out.println (bedate);

}

}
