There are several ways to get current date and time in Java. Java programmers can use modern date and time API introduced in Java 8 (java.time), the classic, outdated API (java.util), and the third-party Joda library. The java.time package Thejava.timepackage contains the main API for...
LocalDaterepresents just a date, without time. This means that we can only get the current date, but without the time of the day: LocalDate date = LocalDate.now();// Gets the current date This time around, instead of initializing a new object, we're calling the static methodnow()whic...
