Write A Program To Print Out Fahrenheit-Celsius Conversion Table?
Oct 14, 2014
This is my program
import java.util.Scanner;
import java.text.DecimalFormat;
public class Lab6 {
public static void main(String[] args) {
int F;
double C = 0;
[Code] ......
output
0 1 2 3 4 5 6 7 8 9
0 degree Fahrenheit equal to :-00.00 degree Celsius
1 degree Fahrenheit equal to :-00.00 degree Celsius
2 degree Fahrenheit equal to :-00.00 degree Celsius
3 degree Fahrenheit equal to :-00.00 degree Celsius
4 degree Fahrenheit equal to :-00.00 degree Celsius
5 degree Fahrenheit equal to :-00.00 degree Celsius
6 degree Fahrenheit equal to :-00.00 degree Celsius
7 degree Fahrenheit equal to :-00.00 degree Celsius
8 degree Fahrenheit equal to :-00.00 degree Celsius
9 degree Fahrenheit equal to :-00.00 degree Celsius
I don't know why the program is not calculating the C degree ?

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++) {
[Code] ....

<import javax.swing.JOptionPane;
public class TempCalc {
public static void main(String[] args) {
//Confirming which conversion to compute.
String FarOrCel = (JOptionPane.showInputDialog("Would you like to calculate a Farenheit value or a Celsius value? (Enter Farenheit or Celsius)");
[Code] ....
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 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'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?

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;
import javax.swing.JLabel;

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."

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(

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

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 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");

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!

I am trying to create a java file that will print out the temperature in Fahrenheit. This is my code.
import java.util.Scanner;
public class TemperatureConverter {
public static void main(String[] args) {
float temperature;
Scanner in= new Scanner(System.in);
System.out.printf("Enter temperature in degrees Celsius: ");
temperature = in.nextInt();
//Getting a red X next to this line.
fahrenheit = temperature * 9/5 +32;
//Add this line
System.out.printf(+temperature + " degrees Celsius is " + fahrenheit + " degrees Fahrenheit.");
//System.out.println(temp1 + " degrees celsius is " + fahrenheit + " degrees Fahrenheit.");
}
}
I need to know what I am doing wrong. Using Eclipse as my platform. I have entered comments where I am getting red X's.
The error I get when I run the program.
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
fahrenheit cannot be resolved to a variable
fahrenheit cannot be resolved to a variable

I am a student taking a Java programming class. My assignment is to write a program that converts a roman numeral input as entered by a user and converting it to it's integer value (arabic number). These are the methods that I must have in it:
1. Write a method that takes input from the user and passes it to a conversion method.
2. Write a method that yields the numeric value of each of the letters (conversion method).
3. Write a method that outputs the number the user entered and the converted number.
4. Write a main method to test the 3 methods.
I have written the first method, at least I think. Here is what I did there:
public static String romanInput(String number) {
Scanner numberInput = new Scanner (System.in);
System.out.print("Enter a roman numeral: ");
String userInput = numberInput.next();
return userInput;
}
I returned the userInput and I think that is passing it to the conversion method? Now I am working on this conversion method and to be honest I don't know where to begin. I am told how to convert a string in my assignment by the professor. I am told:
- Look at the first two characters. If the first has a larger value than the second, then simply convert the first.
- Call the conversion method again for the substring starting with the second character.
-Add both values. If the first one has a smaller value than the second, compute the difference and add to it the conversion of the tail.
I am also told to use a single-dimensional array. But, I don't know what I am to use a single dimensional array for? So this is what I wrote so far for this method:
public static int numberConversion(int number) {
int romanConv = 0;
char[] romanNum = {'I', 'V', 'X', 'L', 'C', 'D', 'M'};
char[] arabicNum = {1, 5, 10, 50, 100, 500, 1000};
romanNum = arabicNum;
}
I have written a character array for the roman numerals, and then one for arabic numerals, then I set them equal to each other. I also declared an integer variable set to 0 because I think that is what I will be returning at the end of the method. Now I don't know where to start for the conversion algorithm here. I know this is what I have to do, but I don't know how to do it:
1. Add the numbers together if they are in decreasing value or are equal in value. For example: VI is read as 5 + 1 = 6 XVI is read as 10 + 5 + 1 = 16 XXXVIII is 10 + 10 + 10 + 5 + 1 + 1 + 1 = 38
2. Use subtraction if a number is less than the number that follows it. For example, I is less than V, so when I is in front of V, you subtract its value.
3. For example: IV is 5 1 = 4 IX is 10 1 = 9 XL is 50 10 = 40 MCM is 1,000 + (1,000 - 100) = 1,900
I can't use hashtables or enums because I haven't learned about that yet. I have a feeling I need to use a for loop. I know I haven't done any of the actual programming work but I don't know how to begin writing this conversion method.

I have a HSQLDB-database and the update syntax is as follows:
Java Code:
UPDATE table SET column = Expression [, ...] [WHERE Expression]; mh_sh_highlight_all('java');
Now I would like to update a column, with an inner join. Because inner join is not supported in this update-syntax I put the relationship in the where clause:
Java Code:
update table1 set rang=null where table1.column1 = table2.column1; mh_sh_highlight_all('java');
But HSQLDB is always saying to me that there is an syntax error: user lacks privilege or object not found: table2.column1
But I am 100% sure, that there is a table2 with the column1. I have no mistake in writing!

I am working on my java program it prints out a table of angles and the sin, cos, and tan. For extra credit he wanted us to use nest loops to create a space after every five lines. I have come real close to getting this to work but have a problem with the very end of the table. The table needs to stop at 180...
public static void printTable(double angle,double sin,double cos,double tan) { // Method to create a table for the values
for (double j = 0; j <= 180;) {
for (double i = 1; i <= 5; i++) {//loop to print five lines of code
angle = Math.toRadians(j);
[Code] .....
Here is the end of the output of the table:
175.00.0872-0.9962-0.0875
176.00.0698-0.9976-0.0699
177.00.0523-0.9986-0.0524
178.00.0349-0.9994-0.0349
179.00.0175-0.9998-0.0175
180.00.0-1.00.0
181.0-0.0175-0.99980.0175

So, here is the question I have been working on: Write a java class named Time that prompts the user to input the elapsed time for an event in seconds. The program then outputs the elapsed time in hours, minutes, and seconds. (For example the elapsed time is 9630 seconds, and then the output is 2:40:30 ).Hint: an hour has 3600 seconds and a minute has 60 seconds. Use Scanner class for reading the input.
Here is my code:
import java.util.Scanner;
public class Time {
public static void main(String[] args) {
Scanner scan= new Scanner(System.in);
System.out.println("Enter the elapsed time in seconds:");
int totalseconds= scan.nextInt();
[Code] .....
Now, I know I am supposed to use the remainder operator to figure out the time in minutes and seconds, but the hours has be a little confused. Right now this code compiles but gives me an exception.
