passing percent to public int method

I believe the author of the text I am using made an error in the problem he has presented. The problem asks to write a main method that includes a percentage of increase and pass that to an int(parameters) method and recalculate. Below is the entire code I have so far. Is there a solution? The problem seems confusing to me. Thank you all for your help.

import java.util.Scanner;

public class PriceAdjustment {

/**Write a method

* int bumpMe(int price, int increase, boolean updown)

* that accepts a price in dollars and returns a new

* price rounded to the nearest dollar, after

* increasing/decreasing price by increase percent. If

* updown is true then you should increase the price;

* otherwise, decrease the price. Write an appropriate

* main(...() method to test bumpMe(...).

*

*/

public static int bumpMe(int price, int increase, boolean updown)

{

//convert increase to decimal

(double) increase = increase /100; //convert to decimal

double newPrice = price * (1 + increase);

newPrice = Math.round(newPrice);

return newPrice;

}//end bumpMe

public static void main(String[] args) {

//declare variables

int dollar; //original price

int incr; //the increase

boolean priceIncrease = true;

double adjustedPrice; // new price after adjustment

//initialize Scanner

Scanner input = new Scanner(System.in);

System.out.println("Enter the original price: ");

dollar = input.nextInt();

System.out.print("Enter the increased % ");

System.out.println(": (enter - for negative numbers");

incr = input.nextInt();

if (incr <=0)

priceIncrease = false;

System.out.println("Value of dollar = " + dollar);

System.out.println("Value of % is = " + incr);

System.out.println("Value of priceIncrease is = " + priceIncrease);

adjustedPrice = bumpMe(dollar, incr, priceIncrease);

System.out.println("The new price is: " + adjustedPrice);

}//end main

}//end class

I'm not sure I get the logic of the problem then

If the original price is $5 and the increase is 5% then the new price should be %.25 but because the returned value is an int, the returned value is $5. But by what the author asked for, that is probably the correct answer. Right?

And thanks. You are right about the uptown parameter. Thank you.

A can't convert double to int error

Junky,

I re-wrote the bumpMe method as follows and get an the error that I

can't cast double to int: Thanks again

public static int bumpMe(int price, int increase, boolean updown)

{

if(updown = true){

//convert increase to decimal

increase = increase /100;

double newPrice = price * (1 + increase);

newPrice = Math.round(newPrice);

}

else {

increase = increase /100;

double newPrice = price * (1 - increase);

newPrice = Math.round(newPrice);

}

//also tried return (int)newPrice;

return newPrice;
