Json Date \/Date(1389715867000)/ to convert to java.util.Date in java [duplicate]

Answer 1

String policyEffective = ...

long time = Long.parseLong(policyEffective.replaceFirst("^.*Date\\((\\d+)\\).*$", "$1"));
Date date = new Date(time);

The number is a long, ms since 1970 or so, and goes as such into the Date constructor.

Result:

Tue Jan 14 17:11:07 CET 2014

Since you got an illegal argument; maybe you took an int or something else.

Answer 2

import java.util.Date;
public class JsonDate {

    public static void main(String[] args) {
        String jsonDate = "\\" + "/Date(1389715867000)" + "/" + "\\";
        jsonDateToUtilDateConverter(jsonDate);
        System.out.println(jsonDate);
    }

    private static void jsonDateToUtilDateConverter(String jsonDate) {
        String epochDate = jsonDate.replaceAll("[^0-9]", "");

        Date date = new Date(Long.parseLong(epochDate));
        System.out.println("date: "+date);
        System.out.println(epochDate);

    }
}

And output I've got is:

date: Tue Jan 14 21:41:07 IST 2014
1389715867000
/Date(1389715867000)/\

Answer 3

long time = Long.parseLong(policyEffective.subString(
policyEffective.indexOf("(")+1,policyEffective.lastIndexOf(")"))));
Date date = new Date(time);

this way will trim the string from the index of "(" to ")" so it will extract only the number
