Getting Date and Time in JShell

We can work with dates and times in JShell as we work with them in Java programming. The java.time package is already present in the JShell environment.

Example 1

If we want to get the current date with time in JShell by using the below code snippet, using the Date() class.

jshell> new Date()
$1 ==> Fri Feb 28 11:59:23 IST 2020

Example 2

In the below code snippet, we need to get a date with a number of milliseconds using the getTime() or currentTimeMillis().

jshell> new Date().getTime()
$2 ==> 1582871487654

jshell> System.currentTimeMillis()
$3 ==> 1582871513421

jshell> new Date(1582871513421L)
$4 ==> Fri Feb 28 12:01:53 IST 2020

Example 3

In the below code snippet, we need to get the time using the Instant.now() method.

jshell> java.time.Instant.now()
$5 ==> 2020-02-28T07:07:33.941720100Z
