Java uses the get() function of the Calendar class to obtain date and time information
In Java programming, we often need to obtain the current date and time information. Java provides many classes and methods to handle dates and times, among which the Calendar class is one of the commonly used ones. The Calendar class provides many methods to handle date and time operations, including obtaining various parts of date and time information.
In the Calendar class, we can use the get() method to obtain various parts of the date and time, such as year, month, day, hour, minute, second, etc. The following is a simple sample code that demonstrates how to use the get() method of the Calendar class to obtain date and time information:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 |
|
The above code obtains a Calendar object by calling the getInstance() method of the Calendar class, and then Use the get() method to obtain the year, month, day, hour, minute, second and other information, and print it out to the console.
Example of output results:
1 2 3 4 5 6 |
|
The above code only uses the get() method of the Calendar class to obtain date and time information. The Calendar class also provides many other methods for date and time processing. Operations, such as setting the date and time, increasing or decreasing a specific date and time, etc. If you need more functions, you can refer to the Calendar class related content in the official Java documentation.
Summary:
Using the get() method of the Calendar class, you can easily obtain various parts of the date and time information, including year, month, day, hour, minute, second, etc. This information is very helpful for us to handle date and time operations in programming. Using the get() method of the Calendar class, we can flexibly obtain and process dates and times to meet our various programming tasks.
The above is the detailed content of Java uses the get() function of the Calendar class to obtain date and time information. For more information, please follow other related articles on the PHP Chinese website!
