RETURN total:=city*charges;
END CALCULATE_CHARGES;
Write a program to calculate the telephone charges for four customers. The data for each customer consists of NAME, PREVIOUS METER READING, PRESENT METER READING. The difference between the two readings gives the number of units used by the customer for the period under consideration.
The amount due for each customer is calculated by: UNITS USED * RATE PER UNIT + RENTAL CHARGE The rate per unit and rental charge is assumed to be the same for all customers and must be input once only.
Your program must:
a. Input the rate and rental charge b. Read the data for each customer and calculate the amount due c. Print the information under suitable headings d. Calculate and print the total amount due to the telephone company
I have to write a program to calculate my weight on different planets and to do that, I have to read in the surface gravity of all the planets from a file using a separate method from main
public static double[] readGravity() throws IOException { double[] surfaceGravity = new double[8]; Scanner readFile = new Scanner("gravity1.txt"); int i = 0; while (readFile.hasNext()) { surfaceGravity[i] = readFile.nextDouble(); i++; } return surfaceGravity; }
I get this message in the while loop when I try to run the program:
java.util.InputMismatchException; null (in java.util.Scanner)
I have understood my programming class up to this point and now I have been given a lab that I can't figure out for the life of me. Here what I have to do: Write a program that will call a method (called f) to calculate the following function" f(x)=(x^2)-16...this is what the output should be:
I am still new to Java and have an assignment that I am stuck on. I believe I got the boolean function correct, however I cannot figure out what to write in the main function. I have exhausted searching, and trying different loops, arrays, etc.
I have to write a program that asks the user to enter the name of their favorite city and use string variable to store the input. The program should display the following:
-The number of characters in the city name -The name of the city in all uppercase letters -The name of the city in all lowercase letters -The first character in the name of the city
However, I can't seem to get past the following errors;
Programming Challenge #12.java:37: error: variable cityFirstChar is already defined in method main(String[]) char cityFirstChar = city.charAt(0); ^ 8 errors[CODE ----jGRASP wedge2: exit code for process is 1. ----jGRASP: operation complete. [/CODE]
My code is as follows:
import java.util.Scanner;

I have a project which consists of the delivery of an sms containing the national identification number of a user upon request. This request will be in the form of an sms. Say for instance a client sends an sms to the mobile operator, my app would retrieve the national id and communicates it to the mobile operator which would send it the client.
I have downloaded and installed kannel as well the smsc simulator SMPPSim and also gone through some of the documentation. Now my problem is, how can i simulate the reception of an sms? Say for instance a client sends 'nidn 5', i want to be able to take 5 and process it in a servlet to retrieve the associated national identification number. How to achieve this.
I am doing a pretty basic program with a fixed origin city and five destination cities. I am having trouble with entering passenger details. This is what I tried, but then I cannot retain all passenger details to print later on in the final ticket.
System.out.println("Enter flight details of child passengers (below 12 years)"); System.out.println("Enter Name"); for(a = 1; a <= cp; ++a) { //cp is number of child passengers, a is loop variable String name = br.readLine(); System.out.println("1. " + name); }
I'm working on a Weight Conversion program. The code I have for the program is:
import java.util.*; import java.awt.*; import javax.swing.*; public class Frame4a implements ActionListener { public static void main(String[] args) { JFrame f = new JFrame("Weight converter"); JPanel P = new JPanel(); // Make a JPanel;
[Code] .....
The errors I'm getting are:
Frame4a.java:33: error: class, interface, or enum expected public void actionPerformed(ActionEvent e){ ^ Frame4a.java:37: error: class, interface, or enum expected double kp= Double.parseDouble(strkilo);
Write a program which request two weight in kilograms and grams and print the sum of the weight, if the weight are 3kg 500g and 4kg 700g, your program should print 8kg 200g. this is what i have
Scanner input = new Scanner (System.in); double weight, kg, g; int sum; System.out.println("Please enter weight"); weight = input.nextDouble();
write a program which request two weight in kilograms and grams and print the sum of the weight, if the weight are 3kg 500g and 4kg 700g, the program should print 8kg 200. this is what I have so far and there is an error that I can't see:
Scanner input = new Scanner (System.in); double weight, kg, grams; int sum; System.out.println("Please enter weight"); weight = input.nextDouble();
[Code] ....
um = (3kg5oog + 4kg700g)-(this line here is where the error is, it supposed to sum the two statement and print out 8kg 200g but i keep getting the red line, dont know where the error is, dont know if it is the coding or what, where error is, where the coding is not right, I am totally lost here right now, this is the if statement.
You have been given the job of writing a program to assist pilots who fly the Beechcraft Starship-‐‑1 executive aircraft.As with any airplane, it is essential that the pilot know the total weight of the loaded plane at takeoff and its center of gravity. If the plane weighs too much, it won'ʹt be able to lift off. If the center of gravity is outside the limits established for the plane, it might be impossible to control. Your task is to write a program that will determine the total weight and center of gravity of this plane
Inputs: The number of crew members, number of passengers, weight of the forward baggage compartment contents, aft baggage compartment contents weight, and the amount of fuel in gallons are to be accepted as INTEGER values in the order stated. Be sure the input values are within acceptable ranges
Outputs:You must echo the input values, annotated with their appropriate names,calculate and display the total weight, and the center of gravity.
In the "Humidity(%)" row, they come out fine, but when I do this, they come out as 0, which I think would explain why my heat indices are consistently lower than the temperature when the temperature is over 80.
My code:
import java.util.Scanner; import java.io.File; import java.io.IOException; public class HeatIndex { public static void main(String[] args) throws IOException { System.out.printf("%70s", "Heat Index: Key West, Florida");
I want to write a method to print the all the names of a phone book. phoneBook is a HashMap<String, String> , that has names as keys and phone numbers as values.
Reading the documentation for both HashMap and Set, I have more or less an idea of how it could be done but I cant put it on code..
This is wrong. It doesnt compile saying incompatible types. I was thinking first to manage to succeed to get a key from my phone book and then I change it to print all the keys.
- The user runs CarDealer JFrame in which appears a JTexField in which he types in some characters (pretending he types some data about selling licence). - The user clicks on the JButton "Save" that stores the characters typed in inside a String variable called strLicence. - The user clicks on the JButton "Open 'Vehicle Form'" that opens the Vehicle JFrame. - Finally, in the Vehicle JFrame I want to write a code that can see/use the value of the String variable called strLicence.
In other words, for example, I want to store the value of strLicence in a new variable declared in the Vehicle class.
(Actually I'm working with a long and elaborate project for the dissertation of my bachelor's degree, so, for cutting to the chase, I simplified it by creating an essential JFrame project.)
I have a .csv file ,and I have written a jsp code which uploads csv file to a local folder . Now I want to upload that csv file to database using stored procedure. Below I have included the code which uploads the csv to database.
I have been having trouble with a recent hw assignment requiring us to sort user defined data types in an array. so far, i have implemented the sorting algorithms correctly but i cant seem to store a string and an integer together. I have an employee class
[public class employee { private String Name; private int IdNumber; public employee(int IdNumber,String Name){ this.Name=Name; this.IdNumber=IdNumber;}
[Code] .....
And in my app, i create a employee object-----> employee john=new employee(1020, "John");
How can I prompt my insert method to take in employee id and string name together?
I have a main class AddressBook where I use ArrayList<Contact> addressBook = new ArrayList<>(); to add information such as name and phone numbers in my Contact class. How do I go about accessing all the information (names, and phone numbers) that is stored in my Contact class? What happens when I print it out is it only prints out the last input of name and phone number and not the entire collection of names and phone numbers. How do I print out the contents of ArrayList?
The program below is intended to find the arithmetic mean of the numbers stored in the array q in two ways: once by storing the numbers in an ArrayList d, where you allow all the necessary conversions to be performed automatically; and once by storing them in an ArrayList e, where you perform all the conversions by hand. Complete the program.
Here is what I have so far:
double[] q = { 0.5, 2.4, 7.4, 2.8, -6.2 }; ArrayList<Double> d = new ArrayList<Double>(); ArrayList<Double> e = new ArrayList<Double>(); for ( double x : q ) { d.add( x ); e.add ( new Double ( x ) );
[Code] .....
Why does it still show "a / d.size?" I thought I fixed that. Whatever, it's supposed to be "dTotal / d.size()", etc.
I'm using jsf 2 to upload file, first I upload the file in a system directory, then trying to store the path to database with other information, my stuck is that when submitting I upload the file successfully, find it in the right place, find the other information such as description, file name ... in database but don't find the path. this is my managed bean :
