Core Java Programming Course- Time Difference

The video tutorial explains how to calculate the difference between two times using a duration object. It introduces the concept of local time and demonstrates how to create a duration object to find the time difference. The tutorial also covers the ISO 8601 format for representing time durations and periods, explaining how to interpret the format. Additionally, it discusses how to calculate time differences in various units and handle negative differences when the first time is greater than the current time. The session concludes with a brief mention of the next topic, which is date formatting.

What is the purpose of using a duration object in time calculations?

• To format time in a 12-hour format

• To convert time to a different timezone

• To calculate the difference between two times

• To store the current time

In the ISO 8601 format, what does the 'P' in the duration object signify?

• Past

• Present

• Period

• PDT for time

How is the difference between two dates represented in the period object?

• Using hours and minutes

• Using weeks and days

• Using seconds and milliseconds

• Using years, months, and days

What happens to the sign of the difference if the first time is greater than the second time?

• The difference is positive

• The difference is negative

• The difference is zero

• The difference is undefined

Which of the following is a feature of the duration object?

• It automatically adjusts for daylight saving time

• It can only be used for date differences

• It can display differences in various time units

• It can only show differences in seconds
