java 获取unix时间戳

Console.log("使用System.currentTimeMillis()获取毫秒的时间戳");
Console.log(System.currentTimeMillis());

Console.log("使用Instant获取秒的时间戳");
long unixTime = Instant.now().getEpochSecond();
Console.log(unixTime);

System.out.println("将时间戳转为日期");
Instant instant = Instant.ofEpochSecond(unixTime);
Console.log(instant);
System.out.println("使用Date获取时间戳");
Date date = new Date();
long unixTime2 = date.getTime() / 1000L;
Console.log(unixTime2);
