Converting Celsius To Fahrenheit And Vice Versa Using Methods And Loop
Oct 13, 2014
I need to do a conversion of Celsius to Fahrenheit and viceversa using methods and a for loop. The methods are public static double celsiustoFahrenheit (double celsius) and public static double Fahrenheittocelsius (double fahrenheit). It gives me weird numbers and i have to have some format that you can see attached ....
package temperatureconverter;
import java.util.Scanner;
public class TemperatureConverter {
public static void main(String[] args) {
Scanner corvette = new Scanner(System.in);
System.out.printf("%12s%12s","Celsius","Fahrenheit");
[Code] .....

I am trying to write a program converting Fahrenheit to Celsius using a for loop. I get it to run and Fahrenheit goes to a hundred. My issue is that the Celsius just says 100 down the column and is not converting. I have tried messing with it, and can not figure what is wrong with it.
import java.util.Scanner;
public class Controlstatement {
public static void main(String[] args) {
double F = 1.0;
double Celcius = 100;
System.out.printf("%s%20s", "Farenheit", "Celcius" );
for (int Farenheit = 0; Farenheit <= 100; Farenheit++) {
F = Celcius * (Farenheit - 32 * 5.0/9.0);
System.out.printf("%4d%,20.2f", Farenheit, Celcius);
}
}
}
The output looks like this all the way to 100:
Farenheit Celcius
0 100.00
1 100.00
2 100.00
3 100.00

I have a Set S=[1,2,3,4,5,10,12]
Now I want to convert this Set into a Range Statement which is of Form as follows...
Desired Range Statement Form is = 1..5/10/12.
Since 1 to 5 are contigious in my Set, they are represented as 1..5 and 10 and 12 are single non contigious elements they are given a single element with a union (/) Symbol.
Similarly, I want to convert the RangeStatement 1..5/10/12 to Set S=[1,2,3,4,5,10,12].
DO we have any efficient method to o this in Java? if I need to write my own method or is there any inbuilt method to do this.

I have:
Java Code: String s = "111100100111011011000010110011101"; mh_sh_highlight_all('java');
I am trying to convert that to bits/bytes.
I need to make that into a series of bits with the same exact values..."1" = a 1 bit, and "0" = a 0 bit.
Remarkably, I haven't been able to find much on this sort of conversion - possibly I am just not searching with the right keywords? As typically, stackexchange or other parts of the web have the same question that I have, asked (and answered) by many others.
How do I go about doing this?
Furthermore, how would I go about saving this to a file - and are there already good "kinds" of files to save this into. If not, how do I go about making my "own" type of "file."
CONTEXT:
I've written a compression system. To keep things simple, I've been using a string to hold the 1s and 0s, so that debugging is simpler, and overall, everything is easier to write. Now, however, my algorithm is finished - and I'm moving on to create a GUI and a working system. This is the last step that I need for the non-GUI stuff (which I'm writing through javafx by the way - is this the right thing to use? I've been told that that is where people are moving towards. Away from swing).

I'm new to coding and we have an assignment for class to convert fahrenheit to celsius so far this is what i have:
import java.util.Scanner;
public class Lab5 {
public static void main(String[] args) {
//variable dec
Scanner scan = new Scanner(System.in);
double input;
[code]...
This is what he wants us to do "Write a method name celsius that accepts a Fahrenheit temperature as an argument. The method should return the temperature, converted to Celsius. Demonstrate the method by asking the user a temperature value to convert. Then below the result, call a loop that displays a table of the Fahrenheit temperatures 0 through 20 and their Celsius equivalents."

Write java program using table that stores celsius and farenheit values that are equal to one another using a loop. use C 0-20 and convert to farenheit.
I have to use doubles for Celsius and Fahrenheit and in the formula. I get a runtime error with the following displayed:
I will display a table of temperatures in their Celsius and Farenheit equivalents.
celsiusfarenheit
import java.util.*;

double celsius;// Temperature in degrees Celsius minimum
double farenheit;// Temperature in degrees Fahrenheit

Write a CiUI application that converts Celsius temperatures to Fahrenheit temperatures. The user should be able to enter a Celsius temperature, click a button, and then sec the equivalent Flhnfflhelt temperature. Use the following formula to make the conversion: F - - y C + 32..F is the Fahrenheit temperature and C is the Celsius temperature.
Now the program runs (In Jgrasp) But when I Enter a number in the fahrenheit box and hit "COnvert' NOTHING happens. I went over my code and I can't find what seems to be the problem...I tried changing
ActionListener Listener = new ConvertListener();
convertBtn.addActionListener(ConvertListener); <----- I tried changing ConvertListener to just Listener but it gives me more problems
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;

The assignment reads: Develop a Java program (F2C.java) for converting a temperature from the Fahrenheit to the Celsius scale. The program will read the temperature graphically using an input dialog box
(JOptionPane.showInputDialog) and will show also the result graphically on a message dialog box (JOptionPane.showMessageDialog).
I can get my input box to show, but I am unable to get to the output box
What I have came up with:
import javax.swing.JOptionPane;
public class F2C {
public static void main(String[] args) {
// Enter Farenheit
String Fahrenheit = JOptionPane.showInputDialog(

I have followed the instructions carefully but the conversion values are not correct.
Write a program that displays a table of the Celsius temperatures 0 through 20 and their Fahrenheit equivalents. The formula for converting a temperature from Celsius to Fahrenheit is
F - | C + 32
where ¥ is the Fahrenheit temperature and C is the Celsius temperature. Your program must use a loop to display the table.
Code
public class TempConversion
{
public static void main(String[] args) {
for(double i = 0; i <= 20.0; i++) {

So I've been trying to come up with a Farenheit to Celsius converter and back. However, whenever I run the program in JCreator it never recognizes the string "Farenheit". Even if I put that exact thing (I copy/pasted from the if (FarOrCel == "Farenheit")) it keeps asking me for a Celsius value.

I’m trying to write a program in Java that will take the input of a temperature in Fahrenheit and convert it to Celsius and Kelvin. This is what I have so far but when I run the program on Eclipse it says the temp. in Celsius is infinity and the same for kelvin. Why is it not preforming the operation and spiting out the correct numbers?
import java.util.Scanner;
public class Temperature {
public static void main(String[] args) {
// This program converts temperatures from Fahrenheit to Celsius to Kelvin.
double temperature1;// operands
double temperature2;
double temperature3;

I've made a simple program in Java (Eclipse) that converts Fahrenheit to Celsius.The class is:
Java Code: package ehu.student;
public class ConversorTemperaturas {
/*--------------------------------------------------------------*/
/*Clase que dado una temperatura en Fahrenheit la canvierte en C*/
/*--------------------------------------------------------------*/
public float farenheit2celsius (float d){
float celsius, aux;
[code]...
When I write t.farenheit2celsius(25.6), appears the following error: "The method farenheit2celsisus(float) in the type ConversorTemperaturas is not applicable for the arguments (double)"If i change in the class the type float for double there is not problem. Why can't i use the type float?

I've tried a couple ways to do it, and they don't work. I'm aiming for functionality like I got with the regular for loop, but from an enhanced for loop. Is this simply beyond the scope of an enhanced for loop, or am I just not getting the right syntax?
TestObject to1 = new TestObject("first", 11);
TestObject to2 = new TestObject("second", 12);
TestObject to3 = new TestObject("third", 13);
TestObject to4 = new TestObject("fourth", 14);
TestObject to5 = new TestObject();
List<TestObject> testList;
testList = new ArrayList<TestObject>();
[code]....
The TestObject class is simply an int and a String, with getters getInt and getString. It all works fine with the regular for loop.
edit: I should probably mention that I know what I have in the enhanced for loop now will only display the class name and the hash. I've tried adding the .getString and .getInt, and tried a few other ways to make it work. I just reverted to this because it compiles and runs

I am trying to invoke some methods in a for loop in order to print some info stored in a List. But for some reason, compiler pops a message saying "cannot find symbol - method getEmpID(). You are using a symbol here (a name for a variable, method or class) that has not been declared in any visible scope." But I am pretty sure that method getEmpID (as also getName(), getAfm(), and payment() ) have been declared as public.
Note: My List contains objects of different type (SalariedEmployee, HourlyEmployee). I hope this is not the factor causing this problem.
Java Code:
import java.util.*;
abstract class Employee{
private String name = "";
private String afm = "";
private long EmpID;
static long count=0;

I have a problem with functions connected to strings.
I have a random String, e.g. "Hello World!" and I have to change every capital Letter into a small letter and vise versa. This alone would be fairly simple, but I have to do it with two other strings.
lowercase= "abcde...z" and
uppercase="ABCDE...Z". Every small letter stands at the very same position as the capital letter, but in the other string.
There should be a letter for letter search in lowercase and uppercase for the letters of "Hello World".
How I could solve the task, however I need a way to search the first string, here "Hello World", according to position. A statement which does: "Give me the letter of position x". This found letter should be able to be stored in a variable or else be able to be used by another statement. And it should be compatible with a for lope.

I am trying to teach myself a bit of java and came across the following line of code in the degrees to Fahrenheit converter tutorial:
int tempFahr = (int)((Double.parseDouble(tempTextField.getText()) )
* 1.8 + 32);
I know what the code does in that it is getting the value that the user has input in text field tempTextField and is applying the mathematical calculation to convert to Fahrenheit and assigning the result to the variable tempFahr.
I am guessing any value input into a text box is considered a string?I am guessing that Double.parseDouble takes in a string and converts it to a double.I am assuming that by simply putting (int) in front of
(Double.parseDouble(tempTextField.getText())) * 1.8 + 32)
that it calculates the value and converts it to an int?The tutorial says this example is not localizable because the parseDouble method is not localizable - what does it mean by localizable?

I am writing a small program to convert temperature from Fahrenheit to Centigrade. I cannot figure out why I keep getting 0.00 for the Centigrade temperature output. Also, I cannot figure out how to get the F degree symbol before or after the temp. I know in JOptionPane the char = 176 is the code for it but im not sure how to code it into the program. My program keeps saying 0.00 for Centigrade temp on the output ....
import javax.swing.JOptionPane;
import java.text.DecimalFormat;
public class tempConversion {
public static void main(String[] args) {
String newDecimal;
[Code] .....
Okay I figured out the Degree symbol!(String DEGREE = "u00b0") phew... now only if i can get the correct output!
