Thread: help with this code please!!!

Yes please I just can get the program to print out the values it compiles
but is not working

This is the original question
Find below is the complete question

public static double celsiusToFahrenheit(double celsius)

/** Converts from Fahrenheit to Celsius */
public static double fahrenheitToCelsius(double fahrenheit)

The formula for the conversion is:

fahrenheit = (9.0 / 5) * celsius + 32

Write a test program that invokes these methods to display the following tables:
Celsius Fahrenheit Fahrenheit Celsius
40.0 104.0 120.0 48.89
39.0 102.2 110.0 43.33
...
32.0 89.6 40.0 4.44
31.0 87.8 30.0 -1.11

I just want to be able to fit in the those methods in the program and make it work
now is saying [Exception in thread ] "main" illegalformatConversionException

Now is working without me uisng those methods < public static double celsiusToFahrenheit(double celsius){
return celsius=(5.0/9.0) * fahrenheit - 32;
}
public static double fahrenheitToCelsius(double fahrenheit){
return fahrenheit=(9.0/5.0) * fahrenheit + 32;
}>
and am getting a wrong value for celsius column 4
please .....I have tried to paste it here but it does not paste I don't know why sir..

Find below is my exact out put right now ....


|Celsius |Fahrenheit||Celsius |Fahrenheit|

40.0| 104.0|120.0| 184.00|
Press any key to continue . . .

yes, it is suppose to print out like this...
but I have not been able to make it work properly .

40.0 104.0 120.0 48.89
39.0 102.2 110.0 43.33
...
32.0 89.6 40.0 4.44
31.0 87.8 30.0 -1.11

}while(i<=31 && j<=30);
}
}][/QUOTE]
The program do not print the right out put, and I don't know how to use the methods posted above in the program please guidance...

Hey cono if you wanna help you do that ,
please al ready frustrated with this assignment and to be candid you are making things worst
you keep asking same questions all over the place..
i have showed you my code and where am @ .....
so please if you have ideas direct and and if can't no problem
my directed here thought I could get help
Thanks.

please how do I format and wrap the code ,and code tag it? this is my first time using this forum

[code=java]
[/import java.util.Scanner;

public class EX5_8{
public static void main(String args[]){
/* public static double celsiusToFahrenheit(double celsius){
return celsius=(5.0/9.0) * fahrenheit - 32;
}
public static double fahrenheitToCelsius(double fahrenheit){
return fahrenheit=(9.0/5.0) * fahrenheit + 32;
}*/
System.out.println("|Celsius |Fahrenheit||Celsius |Fahrenheit| \n");
double i=40;
double j=120;
do{
System.out.printf(" %3.1f|%11.1f | %3.1f | %8.2f |\n",i,(i*(9.0/5)+32),j,j/(5.0/9.0)-32);
i-=1;
j-=10;
}while(i<=31 && j<=30);
}
}]
</The code is here also import java.util.Scanner;

return celsius=(5.0/9.0) * fahrenheit - 32;
}

return fahrenheit=(9.0/5.0) * fahrenheit + 32;
}*/
System.out.println("|Celsius |Fahrenheit||Celsius |Fahrenheit| \n");
double i=40;
double j=120;
do{
System.out.printf(" %3.1f|%11.1f | %3.1f | %8.2f |\n",i,(i*(9.0/5)+32),j,j/(5.0/9.0)-32);
i-=1;
j-=10;
}while(i<=31 && j<=30);

--- Update ---

I formatted it well now
find above is the code

ok, thanks but please how do include those methods in this program?

In the original question of this assignment we are asked to use
public static double celsiusToFahrenheit(double celsius){
return celsius=(5.0/9.0) * fahrenheit - 32;
}
public static double fahrenheitToCelsius(double fahrenheit){
return fahrenheit=(9.0/5.0) * fahrenheit + 32;
}

But if you look at my code i commented them because any I try to used them methods in my code I have tons of errors,please help me...

am sorry thats just me ..
The question was include in your program

<public static double fahrenheitToCelsisu(double celsius) / /converts from CToF
public static double celsiusToFahrenheit(double fahrenheit) / /converts fromFToC>

--- Update ---

The want us to include those methods in the program
