Source code:

import java.util.Scanner;
public class posnegnum
{
 public static void main (String [] arg)
 {
 Scanner input = new Scanner(System.in);

 int j = 0;

 do
  {
   System.out.println("Enter a number:");
   double n = input.nextDouble();
 
   if( n>0 )
    System.out.println(n +" is a positive number");
   else if( n<0 )
    System.out.println(n +" is a negative number");
   else
    System.out.println(n +" is a zero number");
   
    j++;
   
    System.out.println("do you want to continue? (enter 1 to continue 0 to stop) " );
    j = input.nextInt();
   
  }while(j == 1);
 
 }
