Formatting Table For A Single Error Correction Program

Apr 25, 2014

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.

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...

Error - Formatting Output String

Sep 28, 2014

I have this error that keeps coming up any time I select one of my buttons. It actually doesn't hinder the performance of the project, everything works. But I am concerned I missed something and errors are never a good sign.On a slightly different note, I would like to figure out what the best way to format my output would be? I would like it to display as "100.00 F". I have a couple ideas on how to get the F symbol (or other symbol) by inserting something like

String degreesymbol = "F" or whichever it is and then returning that in the output string later. I can't get the decimal formatted correctly and I don't know how to print the degree symbol.Here is the code

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.text.DecimalFormat;

Sep 28, 2014

I am also having trouble with another program.

Java Code:

import javax.swing.JOptionPane;
import java.util.*;
import java.text.DecimalFormat;
import java.util.StringTokenizer;
public class ShelbyHarms_3_03 {
public static void main (String [] args) {
double a, b, c; //Input sides of triangle
double x; //Perimeter of triangle
double area; //Area of triangle

[Code] .....

Here are the errors:

ShelbyHarms_3_03.java:39: error: variable x might not have been initialized
JOptionPane.showMessageDialog(null, formatter.format(x));
^
ShelbyHarms_3_03.java:42: error: variable area might not have been initialized
JOptionPane.showMessageDialog(null, formatter.format(area));
^
2 errors

Am I not formatting the decimal format right?

Java Program - Distance Traveled (Formatting And Decimal Place)

Apr 10, 2014

I'm having trouble formatting my output and issues with the decimal places. Here's my code:

import java.util.Scanner;
import java.text.DecimalFormat; // Imports DecimalFormat class for one way to round
 public class lab3 {
public static void main(String[] args) {
String heading1 = "Hour", heading2 = "Distance Traveled";
int timeElapsed, hour, speed;

[Code] ....

And here's my output (Click on the image since it's pretty small):

Issue:
1) The Hours 2 and 3 aren't aligned to 1.
2) The 80 and 120 in Distance Traveled have 6 decimal places when it should not have decimals.

Java Program To Implement A Single Linked List Structure

Jul 27, 2014

I'm trying to build a program that contains the ability to:

(1) insert new node at head,
(2) print out contents of the list in order,
(3) remove first node from head,
(4) remove last node from tail,
(5) find a target value,
(6) give total number of occurrences of a target value, and
(7) give total number of items in list.

The areas I'm struggling with implementing are: (

- remove from tail - I know how to find the final node but I can't quite figure out how to set it to null since its initial type is an integer.
- find a target value - how to make the parameters quite workout so the user can simply input an integer value.
- The solution is probably really simple but I can't figure out how to print out the results of these methods when I call them.

public class Node
{
private int data;
private Node link;
// Node Constructor 1
public Node()
{
data = 0;
link = null;

FootballClub should include statistics such as how many wins, draws and defeats an instance of it has achieved in the season, the number of goals received and scored. The number of points that a club currently has, and number of matches played.

Task 2. Implement a class PremierLeagueManager which extends interface LeagueManager. PremierLeagueManager class maintains a number of football clubs which play in the premier league. The class should create a menu based on text input and give the user the choice of:

• Create a new football club and add it in the premier league.
• Delete (relegate) an existing football club from the premier league.
• Display the various statistics for a selected club.
• Display the Premier League Table

Printing Amortization Table For Program

Jul 15, 2014

I am still having trouble with printing an amortization table for my program. This is the example the professor gave us and our program has to print exactly like this:

Please enter the amount of the loan (a number less than $1,000,000.00) 1000.00
Please enter the annual interest rate (between 2.0 and 15.0 inclusive) 10
Please enter the term of the loan (a number of years between 1 and 30 inclusive) 1
Your monthly payment is 87.92
| INTEREST | PRINCIPAL
MONTH 1 : 8.33 79.58
MONTH 2 : 7.67 80.25

[code]....

So far I have it so it works up to the table. How to get it to loop so it will print each month with the principal and interest. This is the part im having trouble with:

double principal = amount;
double principalPaid;
double interest;
double totalInterest;
double balance = amount;

[code]....

Adding And Subtracting In Budget Program - Display Table Showing Transactions

Mar 15, 2014

Budget program. Here is my situation, I have 2 tabs in a GUI, one tab adds a transactions when the add button is clicked, and in the other tab displays a table showing all the transactions. In my code, I want it so that when the user chooses a deposit(combo box variable name = cbType, indexnumber for deposit is 0) it will add to the total and when the user chooses withdraw(index number is 1) then it will subtract it from the total. Here is the code.... (note as well, the code also adds a new row to the table)

//add button clicked
private class BtnAddActionListener implements ActionListener {
public void actionPerformed(ActionEvent arg0) {
((DefaultTableModel)table.getModel()).addRow(new Object[]{
cbMonth.getSelectedItem() + "/" + txtDay.getText() + "/" + cbYear.getSelectedItem(),
cbCategory.getSelectedItem(),

[Code] .....

So when I tested the program with 2 transactions, the first transaction was a deposit and the 2nd transaction was a withdraw. The end product was that both amounts were subtracted from the total. When I did a withdraw first and a deposit second, the amounts were both added together.
