At times, we are asked to enter the date into the current date field and we need to get it from Java. In such cases, we will use the Date class, which will give us the current date and current time, in seconds as well. So every detail about the day, week, month, year, or hour can be read through from Java classes. Java has developed a class called Date, from which we can get all these details.

Date d= new Date();

This Date class comes from the util package, and d is the object of the Date...
