Question

Hero Honda has increased the cost of its vehicles as per the type of the engine using the following criteria:

Type of Engine	Rate of increment
2 stroke	10% of the cost
4 stroke	12% of the cost

Write a program by using a class to find the new cost as per the given specifications:

Class name: Honda
Data members/Instance variables
int type: to accept type of engine 2 stroke or 4 stroke
int cost: to accept previous cost
Member Methods:
void gettype(): to accept the type of engine and previous cost
void find(): to find the new cost as per the criteria given above
void printcost(): to print the type and new cost of the vehicle 

Answer 1

import java.util.*;
class Honda{
int type, cost;

void gettype()
{Scanner sn = new Scanner(System.in);
System.out.println("Enter the type of the Engine");
System.out.println("Type 2 for 2stroke (or) 4 for 4stroke engine");
type = sn.nextInt();
System.out.println("Enter the previous cost");
cost = sn.nextInt();
}

void find()
{if (type = 2) cost = cost + (int) (0.10 * cost);
else if (type == 4) cost = cost + (int) (0.12 * cost);
}

void printcost()
{System.out.println("Type: " + type);
System.out.println("New cost: " + cost);
}

public static void main(String args[])
{Honda obj = new Honda();
obj.gettype();
obj.find();
System.out.println("\n\n");
obj.printcost();
}}
