    Default Hello there everyone!

    Write a class that contains the following two methods:

    /** Converts from Celsius to Fahrenheit */

    Hello there guys please I need help with this program in java
    this what i have done so far , please any help would much appreciated

    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");
    for(double i=40,j=120 ;i<=31 && j<=-1.11;i-=1,j-=10){
    System.out.printf("%3.1f|%11.1f|%3.1f|%8.2f|\n",i, (i*(9.0/5)+32),j,j/i*(5.0/9)-32);

    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

    Welcome fon90
    If you have a question please post it in an appropriate area, this is for saying hi.
    Also please not that posting homework instructions is not posting a question.
