Question

抱歉，我对此很陌生。

this is from another class
private String name;
private String code;
private GregorianCalendar startDateTime;
private GregorianCalendar endDateTime;

this is for main
CourseDetail []c1={new course("Java","AACS 2083",
new GregorianCalendar(2015,06,20,14,00),new GregorianCalendar(2015,06,21,15,00))};

我接近答案吗？

请问如何使用上面的方法将日期传递给GregorianCalendar？抱歉这个虚假的问题...

Answer 1

您可以直接使用util date到GregorianCalendar

Date date = new Date();
GregorianCalendar gregoriancalendar = new GregorianCalendar();
gregoriancalendar.setTime(date);

直接设定日期

GregorianCalendar gc = new GregorianCalendar();
gc.set(GregorianCalendar.YEAR, 2015);
gc.set(GregorianCalendar.MONTH, 7);
gc.set(GregorianCalendar.DATE, 23);

构建者link

public GregorianCalendar(int year,
                 int month,
                 int dayOfMonth)


public GregorianCalendar(int year,
                 int month,
                 int dayOfMonth,
                 int hourOfDay,
                 int minute)

实施例

GregorianCalendar calendar=new GregorianCalendar(2015, 6, 23,23, 12);

Answer 2

您创建一个GregorianCalendar的新对象，然后设置日期：

GregorianCalendar gc = new GregorianCalendar();
gc.set(GregorianCalendar.YEAR, 2015);
gc.set(GregorianCalendar.MONTH, 4);
gc.set(GregorianCalendar.DATE, 20);

Answer 3

  CourseDetail []c1={new Course("Java","AACS 2083",new GregorianCalendar(2015,06,20,14,00),new GregorianCalendar(2015,06,21,15,00))};

哦，最后，我只知道我可以通过这种形式的日期。大家好！
