Answer 1

Answer:

// here is code in java.

import java.util.*;

class Main

{

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

   try{

       // variable to store the number of bottles

       int num_bot;

        Scanner scr=new Scanner(System.in);

        System.out.print("Enter number of bottles of beer on the wall:");

        //read the number of bottles

        num_bot=scr.nextInt();

        // print the output

        for(int i=num_bot;i>0;i--)

        {

         // print the first statement

         System.out.println(i+" beer bottles on the wall");

         // print the second statement

         System.out.println(i+" beer bottles . Take 1 down and pass the bottle around.");

         }

         // when there is 0 bottle

           System.out.println("0 bottles of beer on the wall.");

   }catch(Exception ex){

       return;}

}

}

Explanation:

Declare a variable "num_bot" to store the initial number of beer bottles.Then ask user to give number of bottles.Run a for loop to pass a beer bottle until there is 0 bottle on the wall. When number of bottle is 0 then it will print there is "0 bottle on the wall".

Output:

Enter number of bottles of beer on the wall:3

3 beer bottles on the wall

3 beer bottles . Take 1 down and pass the bottle around.

2 beer bottles on the wall

2 beer bottles . Take 1 down and pass the bottle around.

1 beer bottles on the wall

1 beer bottles . Take 1 down and pass the bottle around.

0 bottles of beer on the wall.
