Answer 3

sorry don't know java

Answer 4

okay who is know about java

Answer 5

for date & time you can use:
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());
}
}
output:
Mon May 04 09:51:52 CDT 2009

Answer 6

Date Comparison:

There are following three ways to compare two dates:

1.You can use getTime( ) to obtain the number of milliseconds that have elapsed since midnight, January 1, 1970, for both objects and then compare these two values.

2.You can use the methods before( ), after( ), and equals( ). Because the 12th of the month comes before the 18th, for example, new Date(99, 2, 12).before(new Date (99, 2, 18)) returns true.

3.You can use the compareTo( ) method, which is defined by the Comparable interface and implemented by Date.

Answer 7

Date Formatting using SimpleDateFormat:
import java.util.*;
import java.text.*;

class DateDemo {
public static void main(String args[]) {

Date dNow = new Date( );
SimpleDateFormat ft =
new SimpleDateFormat ("E yyyy.MM.dd 'at' hh:mm:ss a zzz");

System.out.println("Current Date: " + ft.format(dNow));
}
}

output:

moha i got code for the clock:

public class Clock extends Frame implements MouseMotionListener{
int xmou=200; //set the center of circle

int x=xmou; //x position of Second's hand
int y=ymou; //y position of second's hand
int p,b; //perpendicular and base of Second's hand

int h; //hypotenous(heigth) of clock's hand


double the= -0.1047; //theta for creating outer circle

double thetamin=-0.1047; //theta for minutes hand
int xm=xmou; //x position of minute's hand

double thetah=-0.1047; //theta for hour hand
int xh=xmou; //y position of hour's hand

Answer 14

the code is made using threads

Answer 15

Jeet.in is reffering to http://openstudy.com/code-of-conduct, which stats Don’t post only answers - guide the asker to a solution. There is no guidance here as I can see.

Answer 16

ok bro i do know that direct answers are not allowed but how i can guide her in project its difficult thing its not like mathematics. i m also sorry for doing this but its difficult for me to guide her in java project

Answer 17

Annas I understand but I would of first ask her/him to show some work because clearly this is an assignment. You can tell it is an assignment because he/she posted the assignment. He/she has not done a little bit of code far as we can tell.

Answer 18

Also he has this same post here http://openstudy.com/study#/updates/50031249e4b0848ddd670a2d
He is cross posting.

Answer 19

Also, he did not even answer my question if he wanted to use awt,which you are using or Swing or SWT

Answer 20

moha is a girl... and i just gave the code which can help her... i havent answered the whole assignment.

Answer 21

@moha_10 - You must interact with the people helping you in order to learn. Also, telling people to 'mind their own business' is NOT the way to interact on OpenStudy.

Pick ONE question, and don't simply post your entire assignment - ask a question, get help, and show what parts you understand and what parts you don't.

All clear? Thank you.

Answer 22

@cshalvey look i'm so sorry but he first start look to this plz and there is respect to my queastion
http://openstudy.com/study#/updates/50031249e4b0848ddd670a2d
and he also say explain explain what !!
this is a code i understand by read it
