GUI Java Program - Hex To Binary Converter
Mar 11, 2014
This code is for a GUI Java program that is supposed to convert back and fourth between two numbering systems. For example, binary to decimal or decimal to binary. I have created methods for some of the conversions however, I could successfully develop a method to convert from hex to binary. If you plan to run it to see what happens to the current method that I made please know that in the GUI the north end from left to right is as follows.
The textfield is for user entry of any type of data. The first combobox is for the user specifying to the program what type of data he or she entered. The second combobox is for the user to choose what he wants that data converted to. The button is to convert it. The south side has a textarea that gives out the results. Please note that only some of the conversions work so far. There are comments in the code to label which methods do what converisons. Need to find a method that will convert from hex to binary, what is wrong with the current method.

I have made a Java Binary Encoder and Decoder program and, to date, this is the program I have spent the most time developing.
I have ran Alpha tests to check the functionality is correct and it appears to work well. However I am more interested in the quality of my code ,
The code can be found over at: [URL] ....

I am trying to write a program for converting positive binary inputs into hex. in the hex output the point (".")is missing.
Suppose my expected output is e7.6 , but i am getting e76.
Only the "." is missing.
Here is my BinToHex class..
import java.io.*;
public class BinToHex {
double tempDec,fractionpart;
long longofintpart,templongDec;
String inpu ="11100111.011";
String hexOutput=null,tempDecString,hex = null;
[Code] .....
Here is how decimal fraction is converted into hex or here too...

I am writing a program that converts any base 10 number to bases 2-16. I have the code for everything up through hexadecimal conversion, for that requires the use of letters. I understand an array list may be of use however I do not understand how to use that in this code. Below is what I have so far
import java.util.*;
import java.io.*;
public class convertBase
{
public static void main(String[] args)
{
int base;
int number;
String newNum;
[code].....
I commented out the hexadecimal portions.How would I go about coding for letters?

Java Code:
public class Search
{
public static final int NOT_FOUND = -1;
public static int binarySearch( int [ ] a, int x )
{
int low = 0;
int high = a.length - 1;
int mid;
while ( low <= high )
[Code] ....
I keep getting illegal start of expression at ={-3,10,5,24,45.3,10.5}
It says I have 12 errors and I have tried so many things to fix it and I just don't know what to change to make it work.

I'm (failing at) writing a program that searches an array using binary search, but I can't get it to work.
My code so far is this:
Java Code:
package sorting;
import java.lang.*;
import java.util.*;
public class sorteh {
public static void main(String [] args){
int[] array=new int [20]; //creates new array
for (int x=0;x<array.length;x++){ //populates array
array[x]=x*3+1;
[code]...
I copied what a website did for the sorting part, but if I have low=0 and high=19, wouldn't mid not be an int?

I wrote a java program for my gui number converter app, the main purpose of this program is to make sure that user enters only a binary number for conversion from binary to other number formats. the problem is my program keeps prompting me to enter correct binary number, no matter if i enter correct binary number, it will still keep prompting me to enter correct number. Here is the code
import java.util.*;
public class test {
Scanner key = new Scanner(System.in);
String in;
int b;
public test()

I am having calculation issues converting Fahrenheit to Celsius. The Celsius to Fahrenheit is working properly.
private void convertButtonActionPerformed(java.awt.event.ActionEvent evt) {
int tempFahr = (int)((Double.parseDouble(tempText.getText()))
* 1.8 + 32);// Calculate Fahrenheit to Celsuis:
fahrenheitLabel.setText(tempFahr + "Fehrenheit");
}

I am trying to teach myself a bit of java and came across the following line of code in the degrees to Fahrenheit converter tutorial:
int tempFahr = (int)((Double.parseDouble(tempTextField.getText()) )
* 1.8 + 32);
I know what the code does in that it is getting the value that the user has input in text field tempTextField and is applying the mathematical calculation to convert to Fahrenheit and assigning the result to the variable tempFahr.
I am guessing any value input into a text box is considered a string?I am guessing that Double.parseDouble takes in a string and converts it to a double.I am assuming that by simply putting (int) in front of
(Double.parseDouble(tempTextField.getText())) * 1.8 + 32)
that it calculates the value and converts it to an int?The tutorial says this example is not localizable because the parseDouble method is not localizable - what does it mean by localizable?

90-Point Version Specifics: The 90-point version requires that you write both the fromHexToBin and fromBinToDec methods.
90-Point Version Output
95-Point Version Specifics {The 95-point version requires everything from the 90-point version and adds the fromBinToHex method. For this version, you may assume that the binary number will have a multiple of 4 bits.
95-Point Version Output
100-Point Version Specifics: The 100-point version requires the same methods as the 95-point version; however, the fromBinToHex method needs to be improved so it can convert regardless of the number of bits.
100-Point Version Output
105-Point Version Specifics: The 105-point version requires everything from the 100-point version and adds the fromDecToAny method. For this version, the method needs to be able to convert from decimal to any base between 2 and 10. Base 16 is not required for this version.
105-Point Version Output
110-Point Version Specifics: The 110-point version requires the same methods as the 105-point version; however, the fromDecToAny method needs to be improved so it can also convert to base-16.

I have written a code to get all the nodes below a current Node and it is working but I need to get it to look better if possible. To get the number of nodes below I have created an Array List, which I then go to the first Node below and add all the people to the Array list on the same level till I get to the end of the level, then I go down again until I cannot go down any more. Is there a way I can have my code without having to use an array List? I have put my code below. The brieff about the tree is that you have a parent and below the Parent are children who can have brothers and sisters next to them and after that they also have children below that. The method is trying to find the number of children below any given child
private LinkedList<Node> TempQueue = new LinkedList<Node>();
public int noOfYoungerChildren(Member p1){
Node tmp = find(p1);
return countYoungerChildren(tmp);

I am wondering if there is an easy way to create a java exe(cutable) binary, by packing the JRE and ship it like a compiled C++ bin file? I know JAR is good but, I still prefer to create a standalone install - free exe, no matter if the user has or has not Java installed on her PC.

The assignment reads: Develop a Java program (F2C.java) for converting a temperature from the Fahrenheit to the Celsius scale. The program will read the temperature graphically using an input dialog box
(JOptionPane.showInputDialog) and will show also the result graphically on a message dialog box (JOptionPane.showMessageDialog).
I can get my input box to show, but I am unable to get to the output box
What I have came up with:
import javax.swing.JOptionPane;
public class F2C {

I'm sure the solution is simple, but I cannot find it.

I got part of this converter built and running fine but now it's getting weird. Specifically I am getting to the part where I have to count above ten which means things like attaching Vs to Is and Xs and suchlike.
I know I have to use an .append someplace, I am just not certain how to go about it. I've been playing with it some, but this is honestly the biggest thing I've built so far that actually *ran* so I'm afraid to poke too many holes in it... where do I start? It's not like I can invent another return string and concatenate them. R is what I've got.
package hello;
public class RomansatHomans {
public static void main(String[] args) {
// input fed on this line loops through toRo and comes back as a String
// R
String R = toRo(23);
// int D = froRo("x");

Some conversions work. For example, 77 will be correctly converted to 63, and 77777777 will be converted to 16777215. However, some conversions do not work. An example of this is 775002 gets converted to 74898.
