My log file is empty

The problem with the code below is that, after running the application, "log.txt" is empty. Why? I looked over the code, but i can't find something wrong. package Main;

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

public class JavaApp1 {

    public static void main(String[] args) throws IOException {
        File file = new File("log.txt");
        PrintWriter Log = new PrintWriter("log.txt");

        int Line = 1;

        Scanner ScanCycle = new Scanner(System.in);
        System.out.println("Cate numere doriti sa fie afisate?");
        int Cycle = ScanCycle.nextInt();

        Scanner ScanRange = new Scanner(System.in);
        System.out.println("Care este numarul maxim dorit?");
        int Range = ScanRange.nextInt();

        Random Generator = new Random();
        for (int idx = 1; idx <= Cycle; ++idx){
            int Value = Generator.nextInt(Range);
            Log.println("(" + Line + ")" + "Number Generated: " + Value);
            Line = Line + 1;
        }
    }
}

You need to flush your character stream out. Call close()[which internally calls flush()] or flush() on your PrintWriter instance.

    PrintWriter log = new PrintWriter("log.txt");
    //your code
    log.close();
