    Default Converter

    Hello there

    i was wondering if someone is able to help me,
    im kinda trying to make converter between 2 parameters which the user need to type,
    and compare them ,same about the amount (the user needs to insert that parameter (the amount of the value))
    im kinda getting confused how to write it right, i've made a start and not sure how to continue it, and i would gladly take any offers
    suggestion about it

    Thanks

    import java.util.*;
    public class Converter
    {
    	static Scanner reader=new Scanner (System.in);
    	public static void main (String[]args)
    	{
    		int amount=0, insertGold, insertCPs;
    		double cpsPrice, goldPrice;
    		System.out.println("What do you want to convert (cps silver)");
    		int cp=reader.nextInt();
    		int silver=reader.nextInt();
     
    		if ((silver==1)&&(cp==0))
    			System.out.println("Type in the amount of the silver that u want to convert into cps");
    			insertGold=reader.nextInt();
    			System.out.println("Type in the amount of the cps that u want to buy");
    			insertCPs=reader.nextInt();
     
    		if ((silver==0)&&(cp==1))
    			System.out.println("Type in the amount of the cps that u want to convert into silver");
    			insertCPs=reader.nextInt();
    			System.out.println("Type in the amount of the silver that u want to buy");
    			insertGold=reader.nextInt();
     
    	}
    }

    Yeah as you can see ima newbie
    i was thinking maybe it's possible to make boolean access to those ifs...

    Can you explain what the program is supposed to do? Also could give an example of the input to the program and what it is supposed to output with that input.
    If you don't understand my answer, don't ignore it, ask a question.

    technically it should work as a converter that the user inputs the parameters,
    with the price, and amount of each side.

    i kinda getting confused by my self right now....
    that based idea is like you want to buy 10apples.
    the price (the user need to input) x
    output how many he can buy in that amount ,and will something be left. Something like that... .
    hope it's enough to understand the idea that im trying to explain.

    well for example:
    Amount: 1cp
    buyPrice: lets say 100,000
    sellPrice: 110,000
    Ratio of the gaining: (output) 110%
    profit: 10% (10k)

    and the opposite ..
    amount 1m (gold)
    buyPrice: 10cps
    sellprice: 12 (per those 100k)




    well something like that, it's for trading .... .i hope that the idea is now more understandable

    Your example does not show:
    Which data is the input
    what is the output?

    Can you make two lists? One of the input and one of the output.

    That's good that you are trying to work on the details of the design before trying to write the code.

    When you get a design and need help writing code for it, post the code and ask your questions about the problems you are having.

    Default Re: Converter

    Can you explain what you are stuck on?
    So far you have said:
    The input is: Amount, buyPrice, and sellPrice
    what other things does the program need for input? Are there dependencies between the inputs?

    What will the program's output be? Make a list.
    How does the output depend on the input? Are there formulas?
    If you don't understand my answer, don't ignore it, ask a question.

    Default Re: Converter

    im stuck on the output of the programs, I'm not sure how to put things out so it will make the calculating stuff, how to make the percentage that i mentioned before. and something like boolean rule of:
    Convert in or convert out as the code is written till now,and now as i wrote it.
    about the in put, for now i can't think about anything.

    output is gonna be different for both of sides, but it should be based on:
    How much did the user spend:
    How much the user won on that deal : (example)
    Ratio of the gaining: (output) 110%
    profit: 10% (10k)

    basicly it should me like merchanting stats , if u know what i mean.

    If you don't know specifically what you want the program to do, how can anyone help you write the program?
