Print Out Two Different Tables One For Feet To Meters And Other From Meters To Feet
Feb 19, 2015
I can get this program to run and compile, however, upon printing, I have the lastnumber from each table printing on the next line under their respective tables.
public class Lab6 {
public static void main(String[] args) {
double foot = 0;
double meter = 0;
System.out.println(" Feet Meters");
System.out.println(footToMeter(foot));
[Code]...
and what it prints is this:
Feet Meters
1.0 0.31
2.0 0.61
3.0 0.92
4.0 1.22
5.0 1.53
6.0 1.83
7.0 2.14
8.0 2.44
9.0 2.75
10.0 3.05
3.05
Meters Feet
20.0 65.57
25.0 81.97
30.0 98.36
35.0 114.75
40.0 131.15
45.0 147.54
50.0 163.93
55.0 180.33
60.0 196.72
65.0 213.11
213.11475409836066

I have to do feet to meters code. here is the question. Write a Java program that reads a number in feet, converts the number to meters and displays the result. One foot is 0.305 meters.
here is my code :
import java.io.*;
class FeetToMeters
{
public static void main (String[] args) throws IOException
{
InputStreamReader inStream = new InputStreamReader (System.in);
BufferedReader stdin = new BufferedReader (inStream);
[Code] ....
I have seen alot of people use the scanner tool for the start of it but we never learned it as it is an online course but we may end up learning it farther on in our java programming. we have just started with the input and output stuff.

Pretty much what im trying to accomplish, i need to write a program that figures out the distance between one point to another, using miles and feet..
Heres how it has to look: "The distance from my uncles house is ___ miles, or ____ feet."
I can get it to run if i add only whole miles..but when i try to add 8.5 miles, and compile, the program flips out..I know i need to use a double somewhere, but cant figure it out, here is my code..
import java.util.Scanner; //required for input
public class feetToMiles {
public static void main (String[] args){
//Create new scanner object called input
Scanner input = new Scanner (System.in); //allows for input
[Code] ....

I have a program where the user enters in the miles and then it is supposed to get multiplied by feet but I keep getting this error.
GetUserInfo.java:12: error: bad operand types for binary operator '*'
int total = name * feet;
^
first type: String
second type: int
1 error
This is my code so far :
import java.util.Scanner;
public class GetUserInfo
{
public static void main(String[] args) {
String name;
int miles;
[Code] ....

1. Land Calculation
One acre of land is equivalent to 43,560 square feet. Write a program that calculates the number of square feet in a tract of land with 3.5 acres. Hint: Multiply the size of the tract of land (in acres) by the number of square feet in an acre to get the number of square feet in the tract.
a) You must have a variable called nrAcres where you will store the number of acres in the track.
b) Output must look as follows:
Size of land in acres: 3.5
Size of land in square feet: 152460
c) if the value of the variable nrAcres is changed the output should change accordingly. In other words: it would be wrong to have the following statement:
System.out.println("Size of land in square feet: 152460");
previous statement will print the correct output but will not change if you change the value of nrAcres.

this is what i got so far
public class Land
{
public static void main(String[] args){
double nrAcres = 3.5;
int feetInAcre = 43560;
double feetInTract = nrAcres * feetInAcre;
System.out.println("Size of land in acres: " + nrAcres + "
Size of land in square feet: " + feetInTract);
}
}
i tried to compile it but it says
error: class names, Land, are only accepted if annotation is explicitly requested 1 error
what is wrong with my code

I have 2 tables on 1 database
Table A, Table B
I need to evaluate a query by joining these 2 tables and then update the results in the 3rd table in another database. I need to use stateless session bean using JPA I believe. I need 3 Entities for each of the tables here.

We started learning about tables and have a little program. The teacher gave us an excercise and doesn't works (not running), I receive too many errors. So any simple java program with tables with 20 numbers, that is giving random numbers?

I am creating a portal using JSP and MySQL with eclipse IDE. I have a scenario where data is stored on draft table and is retrieved then stored on another table. I need the entry in the draft table to be deleted after the insertion. When I tried to run the code it redirects to success page but makes no impact on database(neither inserts not gets deleted).
<%@ page import="java.sql.*" %>

I am writing a class which formats console output as a table. It displays the type of an entry, the name of an entry, and the data for an entry. I am stuck on a required for loop which appends a tab character to a string, for formatting it as a table. It doesn't seem to be adding any of the tabs and I can't tell what I've done wrong. As far as I can tell the contents of the loop are never reached, and I can't make sense of it.
The ConsoleWriter class that contains the code that is in error...
Java Code:
package frontend;
public class ConsoleWriter {
private static String tabbedData(String data, int min) {
System.out.println(); //for debug
int tabcount = 0;
int len=8*min;
[code]....

I've been using a Java applet for sports tables.It has been very useful for me. However, the recent developments from the people at Oracle have made this program impossible to use. The point is that I need this program and I need it fast.I've been in touch with the person who once created this applet and he has no intentions at all to upgrade it or do anything to make it function. How to make the program works with their new updates.

I am trying to retrieve data from my database by joining my tables. So far i have managed to join my four tables in my database and retrieve all the information in that table. Now what i want to do is create a prepared statement in java that allows me to retreive certain data. Here is my joining query.
SELECT student.idNumber,student.names, student.surname,
course.description,
coursemarks.mark,
class.form,class.id
FROM `student`
LEFT JOIN `coursemarks` on student.idNumber = coursemarks.studentid
LEFT JOIN `course` on course.courseid = coursemarks.courseid
LEFT JOIN `class`on student.idNumber = class.studentID;
What I want is to select all the data depending on the class passed and the form passed, e.g a person might decide to select a certain form only or a certain form and class

Basically the class is supposed to have a static variable that keeps track of the number of companies (numberOfCompanies) that have been created and a static method that returns the value of this variable. I need to have a constructor and a method to addEmployee, a method to printCompany, and a toString method. The addEmployee method will check that there is only 1 salesperson, 2 designers, and 4 manufacturing persons at a time and will check that there are no more than 7 employees of the company.
The addEmployee method will return a String indicating what the error is (i.e. "There is already a sales person in this company") or a null if the employee was added. If attempting to name a third company, an error message will be shown. what i have so far but my print company mmethod returns null company class :in which i am obliged to use inputdialog because it says that it cannot return void when i use the showmeassage diaolog.
company class:
import java.util.ArrayList;
import javax.swing.JOptionPane;
public class Company {
private ArrayList<Employees> list ;
private static int numberOfCompanies;
[Code] ....
error message when print button is clicked:
Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: JOptionPane: parentComponent does not have a valid parent
at javax.swing.JOptionPane.createInternalFrame(Unknown Source)
at javax.swing.JOptionPane.showInternalOptionDialog(Unknown Source)

I am currently trying to print a Diamond using for-loops but I seem to be confusing my self / over-complicating it.
This is what I have so far [URL]). When I run the code I get [URL].
I want to duplicate it on to the other side but I can't seem to be able to figure out a working for-loop to print it out.
Also, is there a faster/efficient method of doing something like this?
