Answer 1

DuckDuckGoose.java

import java.util.Scanner;

public class DuckDuckGoose {
   public static void main(String[] args) {
       // Scanner class object to get the input from user

       System.out.print("Enter the number of kids in the circle: ");
       int numberOfKids=input.nextInt(); // accept the number of kids from user
       System.out.print("Enter the number of ducks called before goose: ");
       int numberOfDucks=input.nextInt(); // accept the number of ducks called before goose
       int gooseSelected;
       // if goose called in first round
       if(numberOfKids>=numberOfDucks)
           gooseSelected=numberOfKids-numberOfDucks;
       else
           // if goose called in other then first round
           gooseSelected=numberOfDucks%numberOfKids;
       // print the child number which was selected as goose
