java problem

[aura2]

well turns out there is problems

this is mine

import java.io.* ;
public class lab3_141
{
    public static void main(String[] args)
    {
    double area;
    double wood;
    double width;
    double length;
    double drawer;
    double price = 200;


     System.out.print("Enter the length of the desk : ");
     length=MyInput.readInt();
     System.out.print("Enter the width of the desk : ");
     width=MyInput.readInt();

     area = (length * width);
        if (area > 1000)
                price += 75;
        if (area > 2000)
                price += 125;

     System.out.println("Wood Selection!");
     System.out.println("1. Oak - $100");
     System.out.println("2. Mahogany - $150");
     System.out.println("3. Pine - $0");
     System.out.print("Enter the type of wood: ");

     wood = MyInput.readInt();
         if (wood == 1)
          price += 100;
         if (wood == 2)
          price += 150;
         if (wood == 3)
          price += 0;
     System.out.print("Enter the number of drawers: ");
     drawer= MyInput.readInt();

        price += (drawer * 30);
    System.out.println("The cost of your desk is: $" + price );
}
}

when i enter the values 60=leng 48=wid 1=oak 4=drawers
i get the answer 620

However on your program (with slight modifications)

import java.io.* ;

public class labredo
{
        public static void main(String[] args)
 {
                int price = 200;
                int width;
                int length;
                int surface;
                int wood;
                int drawers;

                System.out.print("Enter table surface's width (inches): ");
                width = MyInput.readInt();
                System.out.print("Enter table surface's length (inches): ");
                length = MyInput.readInt();

                surface = width * length;
                if((surface > 1000) && (surface < 2000)) {
                        price += 75;
                }
                if(surface > 2000) {
                        price += 125;
                }

                System.out.println("Wood Selection!");
                System.out.println("1. Oak - $100");
                System.out.println("2. Mahogany - $150");
                System.out.println("3. Pine - $0");
                System.out.print("Which type of wood: ");
                wood = MyInput.readInt();

                if (wood == 1) {
                        price += 100;
                }if (wood == 2) {
                        price += 150;
                }if (wood == 3) {
                        price += 0;    }

                System.out.print("How many drawers would you like - $30/drawer:$
                drawers = MyInput.readInt();

                price += (drawers * 30);

                System.out.println("Your new desk is going to cost: $" + price);
}
}

Using the same values i get 545 which is correct.

What math am i doing wrong?

[aura2]

it was the
if ((area > 1000) && (area <2000) statement

however i dont really understand what that did

sorry if im kind of scatter-brained, i keep fixing and finding new problems. This time im done but i dont understand what the difference was

You're charging them $75 too much like I said in my previous post. You're charging them a $200 fee rather than just a $125. Look at my original and the double condition if statement I have, you should do something similar to it.

That compund if statement is basically an if with two conditions. Translated into words it means: if the area is greater than 1000 AND ( && ) the area is less than 2000, then perform what's under this if statement.

oh, tha makes sense then. I changed mine to something similar. Now i might have a bit of an edge in that class. I appreciate everything
