Convert to Celsius using Methods

TheBlindHatter · 01-27-2014, 02:31 AM

So can anyone convert Celsius using loops and methods? Here are some specific instructions:

Celsius Temperature Table

Where F is the Fahrenheit temperature and C is the Celsius temperature. Write a method named Celsius that accepts a Fahrenheit temperature as an argument. The method should return the temperature, converted to Celsius. Demonstrate the method by calling it in a loop that displays a table of the Fahrenheit temperature 0 to 20 and their Celsius equivalents.

I started you off can you finish and modify?

Code:
public class conversiontable
{
  public static void main(String [] args)
  {
    System.out.println("The following is a table that converts Celsius to Fahrenheit:");
    System.out.println("Celsius    Fahrenheit");
    for (int c= 0; c <= 20; c= c+1)
    {
      int convertf= (c*9/5)+32;
      int f= convertf;
      System.out.println(+c+"          "+f);
    }
  }
}
/* The following is a table that converts Celsius to Fahrenheit: 
Celsius    Fahrenheit 
0          32 
1          33 
2          35 
3          37 
4          39 
5          41 
6          42 
7          44 
8          46 
9          48 
10          50 
11          51 
12          53 
13          55 
14          57 
15          59 
16          60 
17          62 
18          64 
19          66 
20          68

dont know if i understood well !! what u did here already converts from f to c from 0 to 20 !! so u did the job if i understood well u need a method to convert ?

i think that's what u've asked for:

Code:
package conversiontable;

public class Conversiontable {

    public static int convert(int c) {
        int f = (c * 9 / 5) + 32;
        return f;

    }

    public static void main(String[] args) {
        System.out.println("The following is a table that converts Celsius to Fahrenheit:");
        System.out.println("Celsius    Fahrenheit");
        for (int c = 0; c <= 20; c = c + 1) {

            System.out.println(c + "          " + convert(c));
        }
    }
}
