I was asked to work on building a program that can convert Fahrenheit to kelvin. Need to create a for loop that spits out the value of kelvin for every degree increase from 32 degrees Fahrenheit to 100 degrees Fahrenheit.
View RepliesI’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;
[Code] ....
Every time I input a number for fahrenheit, I always get 273.15. Everything compiles, the only problem is that run-time error. I need getting fahrenheit to exactly change to kelvin.
//my class
public class TempConversion
{
private double fahrenheit;
public TempConversion() {
fahrenheit = 0;
[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
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.

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");

How to convert this program from a while loop to a for loop.

So i'm writing a for loop to convert any number entered to base 10 with any base provided as well. My code does not work because I need a way to reverse the code order, so the new number is printed correctly with the given base. My code so far:
public static void main (String[] args) {
Scanner kb = new Scanner (System.in);
System.out.print("Enter a number :: ");
int numOriginal = kb.nextInt();
System.out.print("Enter a base :: ");
int base = kb.nextInt();
[Code] .....
newBase has a problem with how it calculates the new number, looking for correct newBase code for conversion?
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

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'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;

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."
I am new to java and I am trying to learn a little about GUI. I found this problem of creating a converter for temp from farenheit to celcius. I have everything working, except for when I hit the converter button... it does not convert.
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;

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(
[Code] .....
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] ....
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 new to Java, programming, and intelliJ. I am trying to make a BMI Calculator using this code as my initial template which converts Fahrenheit to Celsius.
import javax.swing.JFrame;
public class Fahrenheit
{
//-----------------------------------------------------------------
// Creates and displays the temperature converter GUI.
//-----------------------------------------------------------------
[code]....
I created a local field within BMIButtonListener for weight, height, resultLabel, and was able to compile but it did not calculate and listed exceptions.
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

[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 don't know why the program is not calculating the C degree ?
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 am trying to print a loop inside an array of a greater size than the loop itself. Like for example I have an array of size 7 but it has only 3 elements.
int[] array=new int[7]
array[0]=2;
array[1]=3;
array[2]=4;
now what I want to do is print these three numbers in a loop so that my array[3]=2;array[4]=3;array[5]=4 ...... till the last one. Also the array could be any size and not just 7.
Here's the code: it's while loop inside a for loop to determine the proper length of a variable:
for (int i = 0; i < num; i++) {
horse[i]=new thoroughbred();
boolean propernamelength = false;
while (propernamelength==false){
String name = entry.getUserInput("Enter the name of horse "
[code]....
I was just wondering what was going on here -- I've initialized the variable, so why do I get this message? (actually the carat was under the variable name inside the parentheses.
I have everything else working. My problem is that when i type "quit" to close the outer loop. It still runs the inner loop. The National Bank manager wants you to code a program that reads each clients charges to their Credit Card account and outputs the average charge per client and the overall average for the total number of clients in the Bank.
Hint: The OUTER LOOP in your program should allow the user the name of the client and end the program when the name entered is QUIT.In addition to the outer loop, you need AN INNER LOOP that will allow the user to input the clients charge to his/her account by entering one charge at a time and end inputting the charges whenever she/he enters -1 for a value. This INNER LOOP will performed the Add for all the charges entered for a client and count the number of charges entered.
After INNER LOOP ends, the program calculates an average for this student. The average is calculated by dividing the Total into the number of charges entered. The program prints the average charge for that client, adds the Total to a GrandTotal, assigns zero to the Total and counter variables before it loops back to get the grade for another client.Use DecimalFormat or NumberFormat to format the numeric output to dollar amounts.
The output of the program should something like this:
John Smith average $850.00
Maria Gonzalez average $90.67
Terry Lucas average $959.00
Mickey Mouse course average $6,050.89
National Bank client average $1,987.67
Code:
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String name = "";
int charge = 0;
int count = -1;
int total = 1;
int grandtotal = 0;
int average = 0;

How do I convert my for loop below to a while and do while loop?
for(int a=1;a<=9;a++){
for(int b=1;b<=a;b++){
System.out.print(a);
}
System.out.println();

I am trying to make a program add values from a loop. So what its supposed to do is search through tokens on an imported file. The file lists State, Capital, and then capital population. Then take the population string, turn it into numbers, and then do stuff with the numbers. First I'm supposed to find the Highest and lowest population of the places in the file (which I did without problem), but the finally thing is I'm supposed to add each found population to the last so I can find the average of the populations.
I just cannot seem to grasp how to do that. I THINK I'm supposed to some how store the given value into a variable, but how do I get that variable to add to the new value?
like...?
Get token -> a
b = a
c = a + b
or wait no.....
Java Code :
import java.io.*;
import java.util.Scanner;
public class CapPopS
{
public static void main(String[] args) throws IOException
{
File stateCAP = new File("state-capital-2004population.txt");
if (!stateCAP.exists())

I am making a program which accepts two user inputs one being a letter either upper or lower case and the other being a number. the out come should be some thing like this:
G
GG
GGG
GGGG
GGGGG
This is assuming the user inputted 'G' and '5'.
here is the code i have so far:
package week10;
import java.util.Scanner;
public class integer {
public static void main(String args[]) {
Scanner user_input = new Scanner( System.in );
[Code] ....
The problem i am having is that i cant get the number that is inputted to be accepted as a variable to be used for the program.
