Multiplication Table - Single Field To Store Integer
Feb 26, 2014
Steps are:
Create a new class, MultiplicationTable, that has a single field to store an integer multiplication table
Create a constructor that takes a parameter for the maximum number to be multiplied in the table. For example, MultiplicationTable(9) would have a maximum value of 81, where as MultiplicationTable(12) would have a maximum value of 144. Initialize the field in the constructor with the appropriate multiplication values.
Create a multiply method that takes two integers as parameters and returns their multiplication value by looking it up in the field. Make sure to test this method with values greater than the max the table should have stored. How can you handle these cases?
Create a main method that repeatedly tests multiply by printing out the entire multiplication table.
So far i got:
Java Code:
package collectionsHw_netid;
class MultiplicationTable {
// field
int mt;
MultiplicationTable(){
{
for (int i=0; i<=9; i++)
[Code] ....
Is my code right? also how do i print it out? the professor told us that everything should be outside of the main method...

noticed that if I use integers only and simple multiiplication to get my exponent results (in this instance I was looking into Base 26) what is returned is odd, BUT consistent results once I surpass the integer upper limit of 2,147,483,647. I anticipated that once this limit was reached the program would blow up somehow, but no.
public static void main(String[] args) throws IOException{
// TODO Auto-generated method stub
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter an integer exponent: ");
int i = Integer.parseInt(br.readLine());
CountAlpha ca = new CountAlpha();
[code]....

I am making rows and columns in the form of a multiplication table, listed below is my code:
package assignments;
public class MultTable {
public static void main (String [] args) {
int row, column, x, y;
for(row = 0; row < 8; row++)
[Code] .....
If you see my sample run you can see that I have the multiplication table down but, I haven't completed it. I have to make the bottom left half of the whole table blank somehow. For example, I have to make it halfway through the middle of the table the bottom left half full of white space...
5 6 7 8 9
12 14 16 18
21 24 27
32 36
90
hm, it's supposed to be the other way around horizontally.

I have a basic html form with one user input text box labeled "Enter a number" and a submit button labeled "Create a multiplication table". This is the working with a servlet to display an html formatted multiplication table. Everything else is working fine just the formatting is off; I can't seem to get the top row and far left column to number properly. It should look like this with the top row of numbers beginning with a blank cell and then numbering 1 thru n (depending on what the user selects. The first column should be the same, a blank cell and then 1 thru n. Then the multiplication table should be in the rows/columns of the table. Picture this:
I can't get mine to start with a blank cell in the top left-hand corner, instead it has 1 in that cell and the table starts calculating with 2x2.
Servlet code:
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
[Code] ....

So I want to format my output in a table much like the one in the book. I have an SECTable class and it displays the table one row at a time. 4 of the rows are in the 2D array in the SECTable class. The decimal position values are just displayed via a loop going from 12 to 1 (8 bits), 21 to 1 (16 bits), and 38 to 1 (32 bits) and the binary position values have their own class which contains an ArrayList of the binary position values as strings. Here's an example of how I want the table to be formatted (this is after an error has been generated so all the rows will be displayed):
Binary Position: 1100 1011 1010 1001 1000 0111 0110 0101 0100 0011 0010 0001
Decimal Position: 12 11 10 9 8 7 6 5 4 3 2 1
Stored As: 0 0 1 1 1 0 0 1
Check Bits: 0 1 1 1
Fetched As: 0 0 1 0 1 0 0 1
Error Check Bits: 1 1 1 0
And I need it to format similarly for 16 bits and 32 bits as well. Here's the display function for the list of binary position numbers:
public void displayList() {
System.out.print("Binary Positions: ");
for (int i = (posNums.size() - 1); i >= 0; i--) {
System.out.print(posNums.get(i) + " ");
}
}
Here are the display functions for the rows (separated them so that there wasn't so much code in one function):
public void displayTable() {
// Print the Binary Position Values
displayBinPositions();
// Print decimal bit positions
displayDecPositions();
[Code] ....
The print3rdRow and print4thRow are booleans to determine whether an error has been generated yet (user chooses from menu to create an error and the program picks a random bit to change and the erroneous data is put in the 3rd row and it's check bits are put in the 4th row). I tried doing spaces but it just wouldn't come out like I wanted.

so for my computer science class, we have the following problem:
In your documentation be sure to say which loop you thought was easier to implement for this program and why Write a program that produces the following outputs. The first line of output must be written using a For-Loop. The second, using a While-Loop and the third using a Do-Loop.
You look at the program and smile because you see that the series is just the numbers 1-10 squared...just one line is in reverse order. No problem! As you start typing you discover that the number 8 key on your keyboard is not working. For this program you are unable to use the multiplication key
So, back to the drawing board. By staring at the sequence a light comes on and you are able to quickly finish this program WITHOUT using mulitiplication (or the Math class/ solve with arithmetic operators +, - or / ) .
Sample output:
For Loop
1 4 9 16 25 36 49 64 81 100
While Loop
100 81 64 49 36 25 16 9 4 1
Do While Loop
1 4 9 16 25 36 49 64 81 100
I have the "for" done, but I did it with a "for" in the beginning but then had a multitude of nested "if" loops so that I could do 7*7=7+7+7+7+7+7+7

I was trying to execute the following program and the multiplication worked but the division didn't work.
import java.util.Scanner;
public class BodyMassIndex {
public static void main(String[] args) {
// Prompt the user for weight and height
// Create a scanner
Scanner input = new Scanner (System.in);
System.out.println("Please enter your weight in pounds");
int weight = input.nextInt();
System.out.println("Please enter your height in inches");
int height = input.nextInt ();
double BMI = weight * (0.45359237)/ (height * 0.0254)*(height * 0.0254);
// the weight * (0.45359237) executed but it wasn't divided by (height * 0.0254)*(height * 0.0254)
System.out.println ("Your BMI is "+BMI);

Write a program that prompts the user for an input number and checks to see if that input number is greater than zero. If the input number is greater than 0, the program does a multiplication of all the numbers up to the input number starting with the input number. For example if the user inputs the number 9, then the program displays the following sum:
9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 362880
That's the question I'm getting and so far all I've got is
import java.util.Scanner;
public class Lab4Q3
{
public static void main (String[] args)
{
int keyboard;

How to define Cell in the table by table event?
I need to process one component drag to the table. I misunderstand, how I can see to which Cell fall the component. I tried to use Event and Mouse event handlers in my custom Cell, but they do not work. I can copy the drag event to the table and table handles it, but how to get needed Cell I cant understand.

I've come across a piece of code and I am totally baffled by how a certain field is being incremented.
public class Foo{
private static int counter;
private final int id = counter++;
public int id(){return id;}
[Code] ....
Now. The output for this is:
0
1
2
3
4
I understand all the code in it quite well. It's all basic. Containers, generics, looping, foreach loop. What I DON'T understand though is how on each iteration of the foreach loop, the call to the method id() returns an incremented number. I am assuming it has something to do with the field "counter" in class Foo being static because when I made it non-static it didn't increment. I must have missed something way back when I started learning Java because I just don't get it.
The id() method only returns the value of the id field in class Foo and that is the value of counter++. counter is not initialized, though I'm guessing it gets the default 0 when the Foo() constructor is run? Or do statics get initialized BEFORE the constructor is even run? Anyway. How does calling the id() method cause an incrementation? I'd understand if there was some code that tracked the number of Foo objects being created and incrementing for each one, but I cannot see how each time the id() method is called it returns an incremented value.

i need to develop a java program in which it will ask the user "Username" and "Password" and by which it will login to a wesite.
I have developed a GUI in which the username should be entered in the User "JTextfield" and Password in Password "JPasswordField". I need to make sure that password should not be displayed in the GUI. but I didnt find a way to parse the string (char) entered in the "JPasswordField" to the website.
It is always passing a 'null' character! I tried to search in internet and i found that it wont be able to pass the passwordfield characters but you will be able to check in the main function itself by comparing with another char array in the main program itself whether the password entered is correct or not.
Is there any alternate way for this?
Objective : Parse the password (which is not displayed in the GUI) to a website or some other function where it will use it

I have a PDF file and I have a text file that contains this data. It has the name of a PDF field along with a database table column name.
Text file: pdfFieldEmployee=Employee; pdfFieldStartDate=StartDate; pdfFieldSalary=Salary; pdfFieldExempt=Exempt
I also have this hash map that contains the database table column names along with their corresponding values:
Employee, Don Parker
StartDate, 5/6/2000
Salary, $55000
Exempt, N
How would I read through the text file and the hash map and at the same time do this:
if the pdf field is equal to pdfFieldEmployee, then set pdfFieldEmployee equal to Don Parker.
if the pdf field is equal to pdfFieldStartDate, then set pdfFieldStartDate equal to 5/6/2000.
and so on and so on. I would prefer to do this with a loop because I think it would take less code than writing a bunch of if statements.

I have a question about JTextArea colors. When i set the color to blue and then write something on the JTextArea (JTextArea.append) and then set it back to black everything will be black. How can i solve that? Like in Notepad++ or Eclipse when you write keywords in a JTextArea (where you write your code) only some words change color.
This is my code:
// All the imports
public class whatever extends JFrame {
JTextArea a = new JTextArea();
public whatever() {
super("Title");
