    Post How do I output information from my Method to the user as a table?

    For my program, I'm trying to use data from a file that will take the numbers(which stand for Celsius) and use them to calculate standard deviation/convert to Fahrenheit. I've already created the methods for the calculation but I'm not sure what is the right way of outputting the information from those methods to the user when I run the code.

    I've tried:
    sDeviation(celsius);
    double fDeviation = sDeviation(celsius);

    import java.io.File;
    import java.io.FileNotFoundException;
    import java.util.Scanner;
     
    public class ProceduralReview {
    	public static void main(String[] args) {
     
    		//making the arrays
    		int[] year = new int[165];
    		double[] celsius = new double[165];
     
    		File file = new File("tempsLA.txt");
    		Scanner input = null;
     
    		try {
    			input = new Scanner(file);
    		}//end try
    			catch (FileNotFoundException e) {
     
    			//In case file isn't found
    			System.out.println("File not found.");
    			e.printStackTrace();
    			System.exit(0);
     
    		}//end catch
     
    		int index = 0;
    		while(input.hasNextLine()) {
     
    			year[index] = input.nextInt();
    			celsius[index] = input.nextDouble();
    			index++;
     
    		}//end while
     
    		//Print table
    		System.out.println("Year\tCelsius");
    		printTable(year,celsius);
    		System.out.println("");
     
    		//Print Final Table
    		System.out.println("Showing all of the years where the temp is at least 1 standard deviation of the mean:" + "\n");
     
    		System.out.println("Year \t Celsius\tFahrenheit");
     
    	}//end main
     
    	private static void printTable(int[] year, double[] celsius) {
     
    	    //for loop
    	   for(int i = 0; i < year.length; i++) {
    				System.out.println(year[i] + "\t" + celsius[i]);
    			}
     
    	  }//end printTable
     
    	//Celsius to Fahrenheit conversion
    	public static double cfahrenheit(double celsius) {
    		double fahrenheit = (celsius*1.8)+32;
    		return fahrenheit;
    	}
     
    	//Deviation formula
    	public static double sDeviation (double celsius) {
    		double mean = celsius/165;
    		double subtractSquared = Math.pow(celsius - mean, 2);
    		double deviation = Math.sqrt((1/165)*subtractSquared);
    		return deviation;
    	}
     
    }//end class

    Here is where the value for Fahrenheit is computed:
    //Celsius to Fahrenheit conversion
    	public static double cfahrenheit(double celsius) {
    		double fahrenheit = (celsius*1.8)+32;
    		return fahrenheit;
    	}

    Here is where the lines should be printing out on the report:
    //Print table
    		System.out.println("Year\tCelsius");
    		printTable(year,celsius);
    		System.out.println("");
     
    		//Print Final Table
    		System.out.println("Showing all of the years where the temp is at least 1 standard deviation of the mean:" + "\n");
     
    		for(int i = 1; i < year.length; i++) {
     
    		}
    		System.out.println("Year \t Celsius\tFahrenheit");
     
    	}//end main

    Please post any code here on the forum, not though a link. Be sure to wrap the code in code tags.

    Please edit your post and wrap your code with code tags:

    Fixed/edited. The code should be there I believe.

    Ok, that's good. Now can you add some comments to the output that show where the problem is?
    Also show what the desired output is.

    All set I do believe I did it correctly. I also want to output the math/data from my Fahrenheit method which does the conversion of Celsius to Fahrenheit, but basically, a table to something that is shown is desired.

    Can you show a small sample exactly of what you want the program to print out?
    I do not see anything different in the Desired Output section you posted other than the word Fahrenheit on one line.

    I edited the Desired Output to show what I am trying to output. For Fahrenheit, it won't be 50.0 the whole way down of course, but rather, it would use the data from the Fahrenheit method in my code and output for the Fahrenheit. The program takes numbers from file input, calculates the new numbers(Fahrenheit) using the Fahrenheit method, then outputs those numbers under the Fahrenheit column. If that makes sense.

    Ok. Where in the code is the value for Fahrenheit computed?
    Where in the code are the lines printed out on the report?
    Can the computed value be added to the print statement so that it is in the print out?

    I edited the post to show the part of the code where Fahrenheit is computed. Also, I have included the code block that is supposed to print the desired table. Lastly, the computed value should be able to be outputted in a print statement. I'm just not sure how it's done which is why I'm here.

    Can you add the value to be printed to the print statement that is in the code?
      System.out.println(year[i] + "\t" + celsius[i]  + ""+  <ADD the value to print here>);
    Is The <ADD the value to print here> what returned by the cfahrenheit method?
    If so call that method there in the print statement with the celsius value that is to be converted.

    Default Re: How do I output information from my Method to the user as a table?

    I could probably add it there I believe, but I haven't been taught how to nor do I know how to add the values from the method there.
    As to whether the <ADD the value to print here> added what you saw as an output for Fahrenheit the answer is no. I manually added the numbers under Fahrenheit to show an example of what I need outputting.
    How would I add the values in:
    System.out.println(year[i] + "\t" + celsius[i]  + ""+  <ADD the value to print here>);
    Based off the cfahrenheit method from my code, what would I type to add those values within the print statement?

    You know how to call a method and assign the value it returns to a variable. You do it here:
    			year[index] = input.nextInt();
    In the same way call the cfahrenheit method and assign the value returned to a variable.
    Then add that variable to the print statement like you did with year[i] and celcius[i]
