 In the above program, we can see that the `names` is an `ArrayList`  and `blogname` is a `String` object.

 When we call the `getClass()` method on these objects it prints its respective datatype.
 true
 false
 ```

 In the above program, I have defined one String `blogname`. I have used the `instanceof` keyword to check if the `blogname` implements the `String` class and it prints `true`. It means the `blogname` is an instance of the `String` class.


 If you know any other way to check the datatype of an object, please comment below to help the community. Thank you.

 See above code as [GitHub Gist](https://gist.github.com/gauravkukade/b1ceabac137864efd7258b60610cd9dd)

 ### Explanation:

 1. In the first case, we have used the `.now()` method of the `Instant` class to get the current timestamp.
 2. timestampFromDateObject: 2021-05-13 20:55:44.187
 ```

 See above code as [GitHub Gist](https://gist.github.com/gauravkukade/a965f1a078d382ff7366e7ba6d13561c)

 ### Explanation:

 1. In the first case, we are got the `timestamp` using the system time in milliseconds. We can get the system time in millisecond using the `System.currentTimeMillis()`.
 ```
 Instant To Timestamp: 2021-05-13 21:07:44.381
 ```
 See above code as [GitHub Gist](https://gist.github.com/gauravkukade/ea3bc951f15be0010569d306ccafa975)

 ### Explanation:

 In the above example, we have used `.from()` of the `Timestamp` class to get the current timestamp from the `instant` object.
 ```
 Timestamp To Instant: 2021-05-13T15:39:08.046Z
 ```
 See above code as [GitHub Gist](https://gist.github.com/gauravkukade/a031b1904d4efaf758a59462ee2dc02e)

 ### Explanation:

 In the above example, we have used the `.toInstant()` method on the `timestamp` object to get the current timestamp (as Instant ).

 We will see how to get the current date-time in java. Also, we will see how we can format them using the SimpleDateFormat.
