write a sample code for Date And Time in java?

Description:java provides the Date class available in java.util package, this class encapsulates the current date and time.

The Date class supports two constructors. The first constructor initializes the object with the current date and time.

Date( )

The following constructor accepts one argument that equals the number of milliseconds that have elapsed since midnight, january 1 1990

Date(long millisec)

Once you have a Date object available, you can call any of the following support methods to play with dates:

Boolean after(Date date)
Returns true if the invoking Date object contains a date that is later than the one specified by date, otherwise, it returns false.
    boolean before(Date date)
Returns true if the invoking Date object contains a date that is earlier than the one specified by date, otherwise, it returns false.
    Object clone( )
Duplicates the invoking Date object.
    int compareTo(Date date)
Compares the value of the invoking object with that of date. Returns 0 if the values are equal. Returns a negative value if the invoking object is earlier than date. Returns a positive value if the invoking object is later than date.
    int compareTo(Object obj)
Operates identically to compareTo(Date) if obj is of class Date. Otherwise, it throws a ClassCastException.
    boolean equals(Object date)
Returns true if the invoking Date object contains the same time and date as the one specified by date, otherwise, it returns false.
    long getTime( )
Returns the number of milliseconds that have elapsed since January 1, 1970.
    int hashCode( )
Returns a hash code for the invoking object.
    void setTime(long time)
Sets the time and date as specified by time, which represents an elapsed time in milliseconds from midnight, January 1, 1970
    String toString( )
Converts the invoking Date object into a string and returns the result.

import java.util.Date;
 
class DateDemo {
   public static void main(String args[]) {
       // Instantiate a Date object
       Date date = new Date();
      
       // display time and date using toString()
       System.out.println(date.toString());
   }
}

out put:
