Java Program to Find out all Prime Numbers From a Given Random Numbers

Find out all Prime Numbers From a Given Random Numbers.

import java.util.*;
class prime
{
  public static void main(String args[])
  {
    int i,j;
    Scanner sc=new Scanner(System.in);
    System.out.println("Enter length of a number:");
    int len=sc.nextInt();
    int n[]=new int[len];
    System.out.println("Enter a random number:");
    for(i=0;i<len;i++)
    {
      n[i]=sc.nextInt();
    }
    System.out.println("The prime numbers are :");
    for(i=0;i<len;i++)
    {
      int count=0;
      for(j=1;j<=n[i];j++)
      { 
        if(n[i]%j==0)
          count++;
      }
      if(count==2)
         System.out.print(n[i]+"\n");
    }  
  }
}
