I don't know that where to end Input Stream? My source code is below.

import java.util.Scanner;
import java.io.PrintWriter;

public class Program
{

    public static void main(String args[]) throws Exception
    {
        Scanner in = new Scanner(System.in);
        PrintWriter out = new PrintWriter
                                            (System.out);

        double numbers[] = new double[100000];
        int i =0;
        double result = 0.0;

        while(in.hasNext())
        {
            numbers[i++] = in.nextDouble();
        }

        i = i -1;

        while(i >= 0)
        {
            result = Math.sqrt(numbers[i]);
            out.println(result);
            i = i-1;
        }

        out.flush();
    }

}

The first while loop is executing infinite time.

Problem no in Java.you write code correct but.Java have Thread class and it's to crawl all over code.

Thread? This is no working: (Потоки? Это всеравно не работает)

import java.util.*;
import java.io.*;

public class BaseClass extends Thread{
    public static Scanner in;
    private static void next() throws IOException{
        if(in.hasNext()){
            double t=in.nextDouble();
            next();
            double n=(double) Math.sqrt(t);
            System.out.printf("%.4f\n", new Float(n));
        }
    }
    public void run(){
        in=new Scanner(System.in);
        try {
            next();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    public static void main(String[] args) throws Exception{
        BaseClass t=new BaseClass();
        t.start();
    }
}

But, if i reading data from file (in=new Scanner(new FileInputStream("in.txt"));) - this working.(но когда я читаю из файла, программа работеат отлично)
