Help to solve my Code of Java

Please this is my Question
(Conversions between Celsius and Fahrenheit) Write a class that contains the following two methods:

/*
* Convert from Celsius to Fahrenheit
*/

public static double celsiusTFahrenheit (double celsius)

/*
* Convert from Fahrenheit to Celsius
*/

public static double fahrenheitToCelsius (double fahrenheit)

Chapter 6 Methods

The formula for the conversion is as follows:

fahrenheit = (9.0 / 5) * celsius + 32

celsius = (5.0 / 9) * (fahrenheit - 32)

Write a test program that invokes these methods to display the following table:

Celsius

40.0

39.0

38.0

37.0

36.0

35.0

34.0

33.0

6.9 (Conversions between feet and meters) Write a class that contains the following two methods:

/*
* Convert from feet to meters
*/
public static double footToMeter (double foot)

/*
* Convert from meters to feet
*/
public static double meterToFoot (double meter)

The formula for the conversion is:

meter = 0.305 *foot

foot = 3.279 * meter

Write a test program that invokes these methods to display the following tables:

Feet

1.0

2.0

3.0

4.0

5.0

6.0

7.0

8.0

9.0

10.0

Meters

40.0

45.0

50.0

55.0

65.0

- _ _ _ _ Feet.

65.574

81.967

98.361

114.754

131.148

147.541

163.934

180.328

196.721

213.115

And this is my code is it correct and what is the compelet of it

public class Lab12 {
    public static double celsiusToFahrenheit(double num){
        double fahrenheit = (9.0 / 5) * num + 32;
        return fahrenheit;
    }

    public static double fahrenheitToCelsius (double num){
        double celsius = (5.0/ 9) * (num - 32);
        return celsius;
    }
    public static double feetToMeters(double num1){
        double meters =0.305 * num1;
        return meters;

    }
    public static double metersToFeet( double num2){
        double feet = 3.279 * num2;
        return feet;
    }
    public static void main(String[] args) {
        double celsius;
        double fahrenheit;
        System.out.println(" Celsuis     Fahrenheit |    Fahrenheit    Celsuis ");
        System.out.println("----------------------------------------------------");
for(celsius = 40.0, fahrenheit = 120.0; celsius > 31.0; celsius--, fahrenheit -= 10){
            System.out.println(celsius + "\t" + celsiusToFahrenheit(celsius) + "|" + fahrenheit + "\t" + fahrenheitToCelsius(fahrenheit));

        }
double feet;
double meters;
        System.out.println(" feet     meters |    meters    feet ");
        System.out.println("----------------------------------------------------");
         for(feet = 1.0, meters = 20.0; feet <= 10.0; feet++ , meters += 5){
             System.out.println( feet + "\t" + feetToMeters(feet) + "|" + meters + "\t" + metersToFeet(meters));

         }




    }
}

i’m lost what is this

This is a school assignment posted, as @AROUNDTHE2 needs help.


Hi @AROUNDTHE2 !
It seems that this post is asking for answers to a school assignment. It is against Replit Ask policy for community members to request or post complete answers to homework-like questions. On the other hand, the community can assist you in working through and understanding the core fundamentals of computer programming to help you figure out your question by yourself, though.
