Can someone tell me why I am not satisfying the tasks

Question about the task

Request parser

Java Core, Level 5, Lesson 12

Under discussion

I am getting the correct output, but it will not verify. Can anyone help me please?

Read a URL from the console.
Display a space-delimited list of all the parameters (The parameters follow the "?" and are separated by "&", e.g. "lvl=15").
The URL contains at least 1 parameter.
The parameters must be displayed in the same order in which they are present in the URL.
If the obj parameter is present, pass its value to the relevant alert method.
alert(double value) - for numbers (fractional numbers have a decimal point)
alert(String value) - for strings
Note that the alert method must be called AFTER the list of all parameters is displayed.

Example 1

Input:
http://codegym.cc/alpha/index.html?lvl=15&view&name=Amigo

Output:
lvl view name

Example 2

Input:
http://codegym.cc/alpha/index.html?obj=3.14&name=Amigo

Output:
obj name double: 3.14

Requirements:

The program should read only one line from the keyboard.
The Solution class must not have static fields.
The program must display data on the screen in accordance with the task conditions.
The program should call the alert method with the double parameter if the obj parameter can be correctly converted to a double.
The program should call the alert method with the String parameter if the obj parameter CANNOT be correctly converted to a double.

I got it after 10 tries. import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.HashMap; import java.util.Map; import java.util.Scanner; /* Request parser */ public class Solution { public static void main(String[] args) { Scanner sc=new Scanner(System.in); HashMap<String,String> map=new HashMap<>(); ArrayList<String> paramsList=new ArrayList<>(); String url=sc.nextLine(); String params=url.substring((url.indexOf("?"))+1); String[] arr=params.split("&"); for(int i=0;i<arr.length;i++){ if(arr[i].contains("=")){ String[] has=arr[i].split("="); map.put(has[0],has[1]); paramsList.add(has[0]); }else {map.put(arr[i],null);paramsList.add(arr[i]); }} ArrayList<String> list=new ArrayList<>(); for(Map.Entry<String,String> pair:map.entrySet()){ list.add(pair.getKey()); } for(String s:paramsList) System.out.print(s+" "); System.out.println(); for(Map.Entry<String,String> pair:map.entrySet()){ if(pair.getKey().equalsIgnoreCase("obj")){ try{Double d=Double.parseDouble(pair.getValue()); alert(d); }catch(Exception e){ alert(pair.getValue()); } } } } public static void alert(double value) { System.out.println("double: " + value); } public static void alert(String value) { System.out.println("String: " + value); } }
