Making A Program That Could Convert Metric Units Into American System
Aug 31, 2014
I just started programming yesterday, and I have been making little programs to learn some algorithms and the syntax of java. I tried making a program that could convert metric units into the American system. Whenever I try to compile the code, it shows up as an "incompatible type" error. I know this is probably a very obvious answer to most of you, but I can't figure it out.
import java.util.Scanner;
public class MetricToAmerican
{
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
System.out.println("fWhat measurement would you like to convert into US system?
celsius, meter, or kilogram ");
I am trying to write a program that basically determines the max amount of units sold and displays it in a dialog box. Also, the program will display the winning sales associate out of 10. I have wrote the program successfully so far and I can see the maximum number of units sold displayed in the dialog box, but I cannot seem to link the winning sales person.
Here is the code I have typed so far.
//Program to find maximum of three number
import javax.swing.JOptionPane; import java.util.Scanner; public class Sales { public static void main (String[] args) { //Declare variables int num1, num2, num3, num4, num5, num6, num7, num8, num9, num10; int large; int winner;
Creating an array searcher wherein it all depends on the user input. On the first user input it would be the array to search from while the second input would be something to be searched for inside the loop?
The Coupling Corruption Propagation is a OO metric that computed as follows:
Coupling Corruption Propagation = Number of child methods invoked with the parameters based on the parameters of the original invocation.
In the code bellow, a parent method calculateStringBuildSpeed invokes a child method called buildString with the parameter length. The method buildString then calls three child methods of its own callStartTime, callEndTime, and reportResult. The methods callStartTim and callEndTime do not take any parameter.
Therefore, they are effectively immune to any coupling effects that originate from calculateStringBuildSpeed.
However, reportResult takes one variable stringLength that is calculated from the original length variable. If the variable is ever compromised (i.e., it becomes null, has a value that exceeds the int range, or contains a value that reportResult cannot use), then reportResult method could indirectly be corrupted from calculateStringBuildSpeed. Therefore, the coupling corruption propagation is 2 in the following code.
So how can I modify the following code so that the Coupling Corruption Propagation will decrease for example into 1 or 0
Public void CalculateStringBuildSpeed(double numOfElements) { buildString (numOfElements); } . . . public String buildString(double length) {
I have a maths application I am working on in java. This is more related to maths but there could be some here who have worked with calculations like this in their java project.
One could convert from degree to radians and from mph to knots. Could one convert from knots to degree or from mph to degree?
I have to make a program on J2Me which I don't have a clue, the question is :
------------- "Initial display is a text box, with a command button "Generate". When the user enters the list type and clicks on the Generate button, the application asks count of elements and gets the elements and finally displays the list." --------------
I'm doing a project with very defined requirements. Input and output will be done to and from a file. Both the input and output files should have the same format. Each file will consist of a series of lines formatted as follows:
Year Rank Artist Title
That is, each line of the file will consist of the year, rank, artist, and title of a single song, with each of the fields separated by tabs ( ). Output files must maintain this format—you should be able to use the output file of one run of the program as the input to another run.
The first part of my project is to make a Song class, with 6 methods:
public static Song parse(String s) { //Parse a string of the form “Year Rank Artist Title” and create a Song object with the given values. } public int getYear() { //returns the year of the song } public int getRank() { //returns the rank of the song
[Code] .....
So far, I have worked out my Song class like this:
Java Code:
import java.util.Scanner; public class Song { private int year; private int rank; private String artist; private String title;
[Code] ....
I know there's definitely a problem with my parsing, as I am getting the
Exception in thread "main" java.util.NoSuchElementException
when I attempt to input a test String at my variables.
Should I try using StringTokenizer and Integer.parseInt()? I think that perhaps the reason why an error is occuring is because the String is being parsed into Strings and there are no int values to be inputted into the year and rank variables.
How I am supposed to set up the units for my program, and how to correctly display them in the console. Here is a description of my program.
To display the nonzero denominations only, using singular words for single units such as 1 dollar and 1 penny, and plural words for more than one unit such as 2 dollars and 3 pennies. You must use nested if statement when displaying the output.
Sample run: Enter an amount in double, for example 11.56: 1.56 Your amount 1.56 consists of 1 dollar 2 quarters 1 nickel 1 penny
Ok so this is a grading program. I have it so the user can input 2 students and then at the end using an if statement it is suppose to compare them and print out who had the higher grade. Seems simple but it never runs the line of code to print out whos grade is higher:
if (stuAverage > stuAverage2 ){ System.out.println(student + " has the highest grade of all students entered!"); } else if (stuAverage2> stuAverage){ System.out.println(student2 + " has the highest grade of all students entered!!"); }
Here is the Main class:
import java.util.Scanner; public class Main2 { int stuAverage; static String student;
So i was assigned to write a program that would print the answer to the system of two linear equation. the form of ax+by=c and dx+ey=f..I wrote this program, but it is incorrect since I tried it out on my terminal and I keep getting incorrect values.
import java.util.Scanner; public class Quest4 { public static void main(String[] args) { Scanner input = new Scanner(System.in);
I need to convert units accurately. Some of these units include angstroms (0.1nm) and astronomical units or light years. I can't seem to accurately perform these equations (probably mostly because of lack of a proper conversion formula). For example:
To perform the conversion right now, I'm simply multiplying the angstroms by 0.00000000000001799856. However, inputting 55560000000000 (angstroms in one league) results in 0.9999999936. Why is this? Is it possible to work around it? I believe there's a term for the inability for a computer to process 1/3rd properly, but I can't remember what it's called - is that the problem?
I am using BigDecimals for all equations.
Edit: a mod can change the title if they think another is more fitting.
Write a program that will provide temperature conversions between degrees Fahrenheit and degrees Celsius. Provide a method that will take an argument representing a temperature in Fahrenheit degrees and return the equivalent temperature in degrees Celsius. Also provide a method that will take an argument representing a temperature in degrees Celsius and return the equivalent temperature in degrees Fahrenheit. Conversion formulas are as follows: F = 9./5. * C + 32, C = 5./9. * ( F - 32 ), where F = Fahrenheit temperature and C = Celsius temperature. You must prompt for input using the Input class methods that are provided as a download for this unit.
I have two questions, 1st is why won't I get an output from my program when I run it? 2nd is how do I prompt for input using the Input class methods downloaded? The downloaded files are in .class form, and won't show any output when I run them.My code is:
import java.util.*; public class temp { public static void main ( String [] args ) { Scanner in = new Scanner(System.in);
This program deals with a variation of the geographic coordinate system with Greenwich at 51° 28' 38" N. The program will be adding the three values of one coordinate to the three values of the second coordinate. Though the maximum value for seconds and minutes is 59, the user can enter values greater than that number when prompted. The maximum degree is 360 for this assignment though the user can enter values greater than that number.
I'm working on creating the Binary to Decimal program . hat is wrong with this part of my code. Why does it not take you into the loop.
import java.util.Scanner; public class question5 { public static void main(String[] args) { System.out.println("Enter a Binary number. "); // collect Scanner keyb = new Scanner(System.in); //
A GUI program that allows user to enter their name and the program will convert it in number using array.
For example if i input "EUNISE" the output should be 521149195
Because the letter equivalent of
a = 1 b = 2 c = 3 d = 4 e = 5 f = 6 g = 7 h = 8 i = 9 j = 10 k = 11 l = 12 m = 13 n= 14 o = 15 p = 16 q = 17 r= 18 s = 19 t = 20 u = 21 v = 22 w = 23 x = 24 y = 25 z = 26
Netbeans do not detect any syntax errors, but I when I check the build it retuned areas they were a few; It's a simple program name 5 people, gade them then do final calulatoins it's called "grade tool.
heres the code
package gradingapplication; import java.util.Scanner; public class GradingApplication { public static double score(double score){ if(score >= 90){ System.out.println("A");
[code]...
~Problems~
1. It has no gui, I don't know java fx, is java groove used? awt is useful for creating spam bots in robot class, I know it's not very useful but it's so much fun.
I do now have the problem where i have to insert the numbers 1 to 100 individually in order to allow the program to accept a grade as high as 100%.
Also as soon as i type in a negative number the system crashes and shows me a error as attached.
/* Averaging grades To use the Java Swing interface to calculate the average of up to 50 grades.Average is calculated once -1 is entered as a value. The grades are then sorted from lowest to highest and displayed in a content pane which also displays the average. */

Many classes calculate a final grade by using a weighted scoring system. For example, "Assignments" might be worth (weighted at) 40% of your final grade. To calculate the portion of the final grade contributed by the Assignments category, the teacher takes the average of all assignments in the category and multiplies it by the weight (40%). So if a student averaged 90% on all assignments, the teacher would take 40% of 90%, or 36 as the weighted average score for the assignment portion of the the final score. The teacher then calculates the weighted average score for each of the other categories (Quizzes, Midterm Exam, Final Exam, etc.), adds them all together to come up with the final score, and assigns a letter grade based on that score.
Write a Java program that allows the teacher to calculate the grade for a student.
Specification :
Prompt the user to enter the Student ID number, first name, last name, and the average score for each of the following categories:
i am new to programming skills it may be silly question for experience but for me it's new thing. actually i tried a lot but i am facing problem when i trying to take input through Scanner. if i will take input a sentence directly as a string it's working . but when i am trying with Scanner the first word is showing next are not showing
public class Demo2 { public static void main(String[] args) { String s1="hi how are you"; s1=s1.replace('a', 'A'); s1 =s1.replace('e', 'E'); s1 =s1.replace('i', 'I');
[Code]...
this is working properly.
but when i trying with Scanner i am facing problem.
public class Demo2 { public static void main(String[] args) { java.util.Scanner scn= new java.util.Scanner(System.in) String s1=scn.next(); s1=s1.replace('a', 'A');
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 am trying to make a translator program that will convert english to my custom binary. It works going from english to binary, but not going from binary to english.
import java.util.Scanner; public class Translator { public static void main ( String [] args ) { Scanner input = new Scanner( System.in ); System.out.print( "Would you like to convert English to Binary (yes or no)? " ); String answer = input.nextLine();
I develop a finite element code at java. I am looking for efficiency solver and fast for large, sparse , symmetric and positive define matrices .
i used in jblas but i encounter in problem when the matrix has high condition number(ill condition number) and i get error for singular matrix while in mathematica i succeed to solve that system without problems...
Any good solver and fast solver package in java can i use for solving that system?
Write a GUI program to convert all lowercase letters in a string to uppercase letters, and vice versa. For example, Alb34eRt will be converted to aLB34ErT.
