Cant add space separated inputs using for loop

Question

I am trying to add space separated inputs to hashmap using for loop but I got some problems

    int G = s.nextInt();
    for (int i = 0; i < G; i++) {
        System.out.println("List girls qualities");     
        int j=1;
        String gir=s.next();
        String[] numbers = gir.split(" ");
        girlQualities=new HashMap<>();
        for (int x=0;x<numbers.length;x++)  
        {  
            int z=Integer.parseInt(numbers[x]);
            girlQualities.put(j,z); 
            j++;
        }
    }

When I used nextLine() its showing NumberFormatException but even now its not working. Please help me My target is to add numbers in this way

Java has a `Scanner` that is rather sophisticated to parse all kinds of input. — Willem Van Onsem, Apr 12 '17 at 10:22
@WillemVanOnsem does the code OP provided not imply they are using a Scanner called `s`? — Sash Sinha, Apr 12 '17 at 10:24

Thats because the Scanner#nextInt method does not consume the last newline character of your input, and thus that newline is consumed in the next call to Scanner#nextLine

Try

        int G = s.nextInt();
        s= new Scanner(System.in);

And then try nextLine() Method

kindly could you please explain why its happening. nextLine should return current line. I am little bit confused about the above scenario – Rognik Apr 12 '17 at 10:43
