How do u use system date in java?

I only know how in jsp. In jsp, u need to do the code below to get the sysdate

<%@ page import="java.text.*, java.util.Date" %>String date = DateFormat.getInstance().format(new Date());

and you will be able to get the system date which has the format 6/6/04 7:19 AM

iv tried to do this in java

import java.util.Date;public String getSysDate()    {    String date = "";                      String date = DateFormat.getInstance().format(new Date());    return date;    }

there's an error on the variable DateFormat., it cannot resolve symbol.

does anyone know how?

That's because the import for the DateFormat is missing; DateFormat is not in default package (java.lang) so you have to import it as you did it in your jsp either by

import java.text.*;

or by

import java.text.DateFormat;

in the import section then it should work....

import java.util.Date;public String getSysDate()    {    String date = "";                      String date = DateFormat.getInstance().format(new Date());    return date;    }

--> The last post explained successfully why your code couldn't find the command as you didnot declare the exclusive namespace of the package. Another problem your could face here is casting the date from Date type to String. You have to use the toString() method which forms a part of every cannonical class in java. Try the following code instead:==========================================
import java.util.Date;

public string getSysDate {

Date sysDate = new Date ();
String sysDateStr = sysDate.toString ();
return sysDateStr;

}
==========================================

There are several other methods to perform the same. Here's the code:

import java.text.SimpleDateFormat;
import java.util.Calendar;

public string getSysDate {

Calendar sysDate;
String sysDateStr;

sysDate = Calendar.getInstance();
sysDateStr = new SimpleDateFormat("dd-mmm-yy").format(curDate).toString();

return sysDateStr;
}

==========================================

Yet, a third method:

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

public string getSysDate {

// Make sure the Month ("MM") in the "MM-dd-yyyy" is in CAPITALS
SimpleDateFormat DateFormat = new SimpleDateFormat("MM-dd-yyyy");

Date today = new Date();

return DateFormat.Format (today).toString ();

}

Any of them should do your job fine....

Current Sysdate using Java

Using system date in java... How?

 

Import java.Util.Date;

import java.Text.DateFormat;

import java.Text.SimpleDateFormat;

 

private String getDateTime() {

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.Ms");

Date date = new Date();

System.Out.Println(dateFormat.Format(date));

}

 

You can format the date as per your requirement. Here I have tried to print the milliseconds also...Keep Rocking!!

The key here is that "new Date()" returns the system date. How you want to format it is up to you, but any of the above mentioned suggestions are good!

Date outputUsing system date in java... How?

I find this method the simplest and clear of all.

You will need:

import java.Text.DateFormat; /*--to format the date and time(formatting subclasses)*/

import java.Util.Date; /*specific instant in time*/

Creating a simple function like below would be handy;

  public String getdate(){     String mydate = DateFormat.GetInstance().Format(new Date());     return mydate;

 

}

The execution time of a quicksort algorithm in javaUsing system date in java... How?

I have this quicksort algorithm and need to find its execution time using java eclipse, the output should be the sorted array and the time of execution. I would really appreciate your help.

 

public class QuickSort{  public static void main(String a[]){    int I;    int array[] = {12,9,4,99,120,1,3,10,13};    System.Out.Println(" Quick Sortandand");    System.Out.Println("Values Before the sort:and");    for(I = 0; I < array.Length; I++)      System.Out.Print( array+"  ");    System.Out.Println();    quick_srt(array,0,array.Length-1);    System.Out.Print("Values after the sort:and");    for(I = 0; I <array.Length; I++)      System.Out.Print(array+"  ");    System.Out.Println();    System.Out.Println("PAUSE");  }  public static void quick_srt(int array[],int low, int and){    int lo = low;    int hi = and;    if (lo >= and) {      return;    }    int mid = array[(lo + hi) / 2];    while (lo < hi) {      while (lo<hi && array[lo] < mid) {        lo++;      }      while (lo<hi && array[hi] > mid) {        hi--;      }      if (lo < hi) {        int T = array[lo];        array[lo] = array[hi];        array[hi] = T;      }    }    if (hi < lo) {      int T = hi;      hi = lo;      lo = T;    }    quick_srt(array, low, lo);    quick_srt(array, lo == low ? lo+1 : lo, and);  }}
