Generating Random No. In java

import java.util.Random;
class Run
{

public static void main(String args[])
{
 int i;
 Random d = new Random(3);
 Random d1 = new Random(0);
 for(i=0;i<10;i++)
 {
 System.out.println("Print Random value having seed 3  " + d.nextInt(1000));
System.out.println("Print Random value having seed 0 : "+d1.nextInt(1000));
 }
 }

}

output:

Print Random value having seed 3  734
Print Random value having seed 0 : 360
Print Random value having seed 3  660
Print Random value having seed 0 : 948
Print Random value having seed 3  210
Print Random value having seed 0 : 29
Print Random value having seed 3  581
Print Random value having seed 0 : 447
Print Random value having seed 3  128
Print Random value having seed 0 : 515
Print Random value having seed 3  202
Print Random value having seed 0 : 53
Print Random value having seed 3  549
Print Random value having seed 0 : 491
Print Random value having seed 3  564
Print Random value having seed 0 : 761
Print Random value having seed 3  459
Print Random value having seed 0 : 719
Print Random value having seed 3  961
Print Random value having seed 0 : 854

Printing Date in java Program

import java.util.Date;
class New
{

public static void main(String args[])
{

 Date d = new Date();

 System.out.println("Time in millisecond is from 1 jun 1970 " + d.getTime());
System.out.println("Current Date and Time is : "+d.toString());
 }


}

output:

   e:\java_programs>java New
Time in millisecond is  1377282070857
Current Date and Time is : Fri Aug 23 23:51:10 IST 2013
