        String[] v = new String[5];

        for (int i = 0;
                i < v.length;
                i++) {
            //long tempo = (long) (1293861598 + random.nextDouble() * 60 * 60 * 24 * 365);
            DateFormat dateFormat = new SimpleDateFormat("yyyy");
            Date dateFrom = dateFormat.parse("2012");
            long timestampFrom = dateFrom.getTime();
            Date dateTo = dateFormat.parse("2013");
            long timestampTo = dateTo.getTime();
            long timeRange = timestampTo - timestampFrom;
            long randomTimestamp = timestampFrom + (long) (random.nextDouble() * timeRange);
            System.out.println(randomTimestamp);
        }
    }
}

我需要，例如，2012 年 2 月 11 日

使用简单日期格式

SimpleDateFormat formatter= new SimpleDateFormat("dd/MM/yyyy");
System.out.println(formatter.format(new Date(randomTimestamp)));
