here's my solution, its failing in test case 1 and 2 kindly help me understand how can i make it generic public class Solution {

public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);
    int i = scan.nextInt();
    double d=scan.nextDouble();
    String s= "";


    // Write your code here.
      while(scan.hasNext())
    {
        s += scan.next();
        s += " ";
    }
    scan.close();
    System.out.println("String: "+s);
    System.out.println("Double: " + d);
    System.out.println("Int: " + i);

}

}
