hi i am working on a temperautre convertor and it has to have 2 methods and a return value for each method but i dont know how to do it this is what i have so far

import java.util.Scanner;

class Temperature
{
public static void main(String[] args)
{
int Temp1,cel;

System.out.print("What is the temperature you'd like to convert? ");

Scanner myScanner = new Scanner(System.in);

Temp1 = myScanner.nextInt();

cel = (Temp1 / 5) * 32;

System.out.println("Celsius to Fahrenheit = " + cel);


}
}

If you want it oop just create another class that has 2 methods - define an object of the class and use the 2 methods to calculate the totals - it looks like you know the formulas for it.

class BlaineSch {
	celcius(int i) {
		return (i/5)*32
	}
	ferenheit(int i) {
		return (i/32)*5;
	}
}
class Temperature {
	public static void main(String[] args) {
		int Temp1,cel;
		System.out.print("If you would like celcius to ferenheiht type in the number one");
		System.out.print("If you would like ferenheiht to celcius type in the number two");
		Scanner myScanner = new Scanner(System.in);
		Temp1 = myScanner.nextInt();
		BlaineSch Blaine = new BlaineSch();
		if(Temp1==1) {
			blaine.celcius(Temp2);
		} else {
			blaine.ferenheit(Temp2);	
		}
	}
}

I just typed that up in the quick reply box so it probably has enough errors you have to fix in order to actually understand what its doing.

Looks promising, let me help the new commoner !

So, I have done one for you just this time, since I want to be happy and kind, and lol.
So try to figure out what I have done and check here !(Do it for my and yourself please !)

Read them whenever your stuck and need to remind where the walls are around the box; which means before you leave outside the box alone :-)

Cheers !!
Also rep+ me please :x

Noo !
Why you Blaine !!!
:P

[justinb09]

but neither one of these have return parimiters it needs to have them

Uhm, Blaine have a return, statement in each of his converts, you can't have return inside of parameters...(not today at least)

[BlaineSch]

Beat ya to it didnt I? :P

Either way yours looks tested lol mine probably has more errors then a 3 year old doing a "hello world" program :P

[justinb09]

ok do a step by step explanation on how to make my code into 2 methods and have two return values in it and convert from celsius to farenheit and vice versa please use my above code to explain this please show me each step of code

class BlaineSch {

	celcius(int i) {

	ferenheit(int i) {

}

class Temperature {

	public static void main(String[] args) {

		int Temp1,cel;

		System.out.print("If you would like celcius to ferenheiht type in the number one");

		System.out.print("If you would like ferenheiht to celcius type in the number two");

		Scanner myScanner = new Scanner(System.in);

		Temp1 = myScanner.nextInt();

		BlaineSch Blaine = new BlaineSch();

		if(Temp1==1) {

			blaine.celcius(Temp2);

		} else {

			blaine.ferenheit(Temp2);	

		}

	}

}

Well lets see...

//Subclass...

class BlaineSch {

//Celcius converter... with parameter int i, if you put in something...

	celcius(int i) {

//it converts here and returns the value....

		return (i/5)*32

	}

//Fahrenheit converter... with parameter int i, if you put in something...

	ferenheit(int i) {

//it converts here and returns  the value...

		return (i/32)*5;

	}

}

class Temperature {

	public static void main(String[] args) {

		int Temp1,cel;

		System.out.print("If you would like celcius to ferenheiht type in the number one");

		System.out.print("If you would like ferenheiht to celcius type in the number two");

		Scanner myScanner = new Scanner(System.in);

		Temp1 = myScanner.nextInt();

//reference to the stupid subclass...

		BlaineSch Blaine = new BlaineSch();

checks your fukking option from Temp1...

		if(Temp1==1) {

//Counts in the value refers to the subclass method...and returns value...

			blaine.celcius(Temp2);

		} else {

//Counts in the value refers to the subclass method...and returns value...

			blaine.ferenheit(Temp2);	

		}

	}

}

The end
