Answer:
// Here is SammysRentalPrice.java file
// import package
import java.util.*;
// class definition
class SammysRentalPrice
{
// main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// object to read value from user
Scanner scr=new Scanner(System.in);
// ask to enter rented minutes
System.out.print("enter rented minutes: ");
// read minutes
int min=scr.nextInt();
// find hours
int hour=min/60;
//reamining minutes
min=min%60;
// total cost
int cost=hour*40+min*1;
// print cost
System.out.println("total cost is: "+cost);
}catch(Exception ex){
return;}
}
}
Explanation:
Read rented minutes from user and assign it to variable "min".Find the hours from minutes and then update the remaining minutes.After this multiply hours with 40 and remaining minutes with 1.Sum them and this will be the cost of rented a sports equipment.
Output:
enter rented minutes: 145
total cost is: 105
myChairs[199].WoodType is the following accesses the last Furniture object's wood type
d. myChairs[199].WoodType
<u>Explanation:</u>
An array often has the size range of [0- n-1] where n is number of cell for array. For example, when the array has a size of 5, its index starts from 0 and ends at n-1 ie 4.
So according to the question, the array myChairs is an array of objects declared from the class Furniture. Its index starts from 0 and the last object is at 199. So to access the last object’s WoodType, the following accesses it:
myChairs[199].WoodType.
Im not entirely sure but I think it is macro
