In Java, you can use the java.util.Date class to represent dates and times, and you can specify date formats using the SimpleDateFormat class.

Below is an example code for creating a Date type for a specified date.

import java.text.SimpleDateFormat;
import java.util.Date;

public class Main {
    public static void main(String[] args) throws Exception {
        String dateString = "2021-12-31";
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
        Date date = format.parse(dateString);
        System.out.println(date);
    }
}

In the example above, we first defined a string called dateString which represents the date to be created. Then, we used the SimpleDateFormat class to create a date format, specifying the format for the year, month, and date. Next, we called the parse method to parse the string into a Date object. Finally, we printed out this Date object.

When you run the example code above, the output will show “Fri Dec 31 00:00:00 CST 2021”, indicating that the Date type for the specified date was successfully created.

It should be noted that the Date class has been deprecated in Java 8, and it is recommended to use the java.time.LocalDate class to represent dates. Below is an example code showing how to create a specific date using java.time.LocalDate:

import java.time.LocalDate;

public class Main {
    public static void main(String[] args) {
        LocalDate date = LocalDate.of(2021, 12, 31);
        System.out.println(date);
    }
}

In the example code above, we used the LocalDate.of method to create a specific date LocalDate object. Afterwards, we printed out this object.

By running the example code above, the output will be 2021-12-31, indicating the successful creation of a specified date of type LocalDate.
