Store Celsius And Fahrenheit Values Equal To One Another Using Loop
Sep 29, 2014
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.*;
import java.lang.*;
import java.io.*;
class TemperatureConversion {
public static void main (String[] args) throws java.lang.Exception {
double celsius;// Temperature in degrees Celsius minimum
double farenheit;// Temperature in degrees Fahrenheit
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); } } }
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");
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; import javax.swing.JPanel; import javax.swing.JTextField;
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."
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.
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++) {
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.
<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’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 have a JScrollPane with two coulmns. In the first column I have an image pane JTable, and in the second a list with names of sections. This second column I try to divide in two columns, one (the second column) to display the names of the sections (each row contains one name), and in the other column (the third) I want to show some values for every section in the row respectively. But, instead of displaying the desired values in the third column, I get the same names of the sections as in the second column. Here is a part of the code I have:
private Vector<Section>daten = new Vector<Section>(0); //These are the values for the first column in the Jscroll private String[] header = {"Section","calcGYR"}; // These are the values for the second and third column (in this case the header for the both columns public TrafficObserveModel(Vector<Section> daten) { setData(daten);
[code]....
But I don't know how to modify the methods in order to render the desired integer values in the third column.
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.
I need a way to store the pixels values currently on the screen and compare them to the values on the first frame. Right now I'm using glreadpixels as follows:
currentBuffer= BufferTools.reserveByteData(mapSize); glReadPixels(mapStartX, mapStartY, mapWidth, mapHeight, GL_BLUE, GL_UNSIGNED_BYTE, currentBuffer); for (int i = 0; i < mapSize; i++) { if (currentBuffer.get(i) != baseBuffer.get(i)) { //Do nothing continue; } //Do something }
This works perfectly fine but turns out to be a real bottleneck, dropping the fps to a third of what it was. Is there any quicker way? All I'm after is speed, I don't even need to show it on the screen if the comparison is made "behind the scene".
So i wanted to try something new like find an image within an image. So for my "find" method I would like to take an image and use it to scan and compare sum of absolute differences with the bigger image. So that the smallest SAD would be the exact image that I am using to scan. What I am thinking is to put each pixel value of both images into two separate arrays and compare them via Math.abs(image1[i][j]-image2[i][j]); . My only problem is that I do not know how to put each pixel value into an array.
Also, If I only want to compare just the green in the picture. I saw that the Pixel class has a getGreen(); method. If I want to find the SAD of the green, would Math.abs(image1.getGreen()-image2.getGreen()); work? I was planning to have 2 nested loops running through each column and row for each image and just find the SAD of the green value.
I have a problem with my application. It supposed to store 4 different Room objects but when I entered one only it stores tat object variables into all my Array elements. I just need it to store any number of objects as long as it is less than 4.
Java Code:
import java.util.Arrays; import java.util.Scanner; import javax.swing.JOptionPane; class TestRoom { public static void main(String [] args) { String[] roomsInHouse = new String[4];
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())
So I'm trying to write a program that takes in 20 numbers and computes their average and I'm supposed to use a while loop to read the values and to make sure that all the numbers are positive. My while loop is set up and does all the math correctly but I have completely forgotten how to taken 20 numbers from the user all at once and then run them through the while loop.
HERE IS MY CODE SO FAR:
public static void main(String[] args) { int num = 100; int count = 0; int total = 0; while (num >= 0 && count < 20){ if (num %2 == 0){ total += num; count++; } } double avg = total/20; System.out.println("The Result Is: " + avg); }
The program is supposed to print all even and odd numbers between 50 and 100 using ONE while or do while loop. The evens work, but the program terminates after printing 51 for the odds, which doesn't satisfy the second value sentinel value for the while loop.
public class EvenOdd { public static void main(String args[]) { int x = 50; int y = 50; int i = 0; int j = 0; System.out.print("Even numbers between 50 and 100: ");
Write a program that creates an array that can hold 9 double values that represent baseball batting averages for a starting baseball lineup. Use a for loop to populate array with random double values in the range of 0.00 to 0.500. Recall that "double" values are what Java calls "real" numbers. Use a second for loop to print the values in the array with one number per line. Finally, use a third for loop to traverse the array and find and print the maximum batting average in the array. Note: you will need to use String.format to control the precision of a double number when you print it- Here is my code so far:
public class P2F { public static void main (String[] args) { double [] player= new double [9]; //player[0]= Math.random(); for (int index=0; index < player.length; index++) {

When I open the terminal window I get different variations of this [D@4545c5]. I would like to know all the things I am doing wrong.
I have used netbeans to build my app. So there creating jTable is out of my control as that part was inside auto-generated code. I have just used the jTable.setValue().
My problem is, above method is inside a button click event. Updated values not displaying until the loops ends.
Started learning about Array's I'm doing an exercise where you create a for loop that randomly assigns values to each element within the array, but where is my code going wrong?
import java.util.Scanner; public class ArrayExamples{ public static void main(String[] args) { Scanner input = new Scanner(System.in); double exampleArray[] = new double[5]; System.out.print("Enter a Number: "); int num1 = input.nextInt();
I had to write a foor loop to count the values of a stack of quarters from 1.00 to 3.00 and I had to print the values, that I understood and got it working so I taught the next assignment was going to be easier but I am having a hard time with it. For this one I have to write a for loop to print all the positive integer factors of 144 and I am supposed to print of factor per line but I tried doing that but it doesn't work it just prints out 144.
This is my code. The quarter assignment is also in there because it is part of a lab so just ignore that part since it is working correctly.
public class ForLoopPractice { public static void main(String [] args) { // Write a for loop to count out the values of a stack of quarters from $1.00 to $3.00 // Print the value of each iteration. Print this all on one line, rounded to the nearest cent. // To print rounded, use printf, with a placeholder of %.2f // (%f is the floating-point placeholder; the .2 indicates the number of decimal places) /* YOUR CODE HERE */ for (double q = 1.00; q <= 3.00; q += .25)
