Generate Prime Number Series in Java Programming

It is a java program where accept a number form user and generate prime number series from 1 to accepted number.
Example: If accepted number from user is: 1000

Prime number series from 1 to 1000 is:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499, 503, 509, 521, 523, 541, 547, 557, 563, 569, 571, 577, 587, 593, 599, 601, 607, 613, 617, 619, 631, 641, 643, 647, 653, 659, 661, 673, 677, 683, 691, 701, 709, 719, 727, 733, 739, 743, 751, 757, 761, 769, 773, 787, 797, 809, 811, 821, 823, 827, 829, 839, 853, 857, 859, 863, 877, 881, 883, 887, 907, 911, 919, 929, 937, 941, 947, 953, 967, 971, 977, 983, 991, 997

Total 168 prime numbers from 1 to 1000

Program Code
//Prime Number Series
import java.util.*;
class prime_series
{
 public static void main(String args[])
 {
  Scanner object1=new Scanner(System.in);
  System.out.println("********Prime Number Series Program********");
  System.out.print("Enter any number to generate prime no series: ");
  int num=object1.nextInt();
  System.out.println("");
  System.out.println("Prime number series from 1 to "+num);
  System.out.println("");
  for(int i=1;i<=num;i++)
  { 
   int count=1; 
   for(int j=2;j<i;j++)
   {
    if(i%j==0)
    {
     count=0;
     break;
    }
   }
   if(count==1&&i!=1) 
   System.out.print("\t\t"+i);
  }
 
 }
}



Output
Save program as "prime_series.java"
