GUI Java Program - Hex To Binary Converter
Mar 11, 2014This 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.

Also the only string class methods I'm aloud to use are length, charAt, and substring. I just don't know how the get the Unicode value.

Create A Java Program That Accepts A String
Feb 19, 2014So basically I have to create a java program that accepts a string and does the following:
1.) Insert a blank space before capital letters
2.) Convert any capital letters into lower case except the first letter(if it is capital).
So if the user enters "HiMyNameIsJohn", the result should be "Hi my name is john". I am having problems inside my changeMe method. Everything works fine including putting a blank space in between upper case words. So from the previous example, my code would show "Hi My Name Is John". I am having issues making the code to convert the upper case letters into lower case. Im pretty sure the code should be right after the str.insert(i, " "). But I do not how to code it. Ive thought about Character.toUpperCase(ch); but doesnt work.

Swing/AWT/SWT :: Cannot Convert Unicode
Feb 26, 2014Recently I switched a RCP/swing app from using hypersonic to mysql. The problem is that there are some unicode characters in the data. The data now displays with the unicode characters as unicode in the app. I tried printing out the data from the bean and it comes out the same way on the console. If I cut/paste the string from the console and place another print statement inside the bean I get output with unicode from the field and formatted output from the other print statment. Why???
public String getText(){
System.err.prinltn(text); //this is the actual value that comes in from the database
System.err.prinltn("u00e");//this is the cut/past value of what the above line prints except this shows in the console correctly
return text;
}

Servlets :: Unicode Post Request Parameters
Feb 10, 2014I developed some servlet to get unicode parameters via post request. It worked perfectly fine since I set the encoding as below:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
HttpSession session = request.getSession(false);
response.setCharacterEncoding("UTF-8");
response.setContentType("text/html");
request.setCharacterEncoding("UTF-8");
String fileContent = request.getParameter("fileContent");
}
Now that I have set up my dev environment on a new machine with new eclipse, it does not work.
It displays Ï instead of π.
I've already tried adding URIEncoding="UTF-8" to server.xml which did not work since it only affect get not post. I figured out how to get the parameter with correct encoding on the new system:
String[] parameters = URLDecoder.decode(request.getQueryString(), "UTF-8").split("&");
But I cannot believe that this is the solution because then what's the point of having request.getParameter. I already know that:
String sss = new String(fileContent.getBytes(),"UTF-8");
would not work.

GUI Temperature Converter
May 4, 2015I am having calculation issues converting Fahrenheit to Celsius. The Celsius to Fahrenheit is working properly.
private void convertButtonActionPerformed(java.awt.event.ActionEvent evt) {

Degrees To Fahrenheit Converter
Mar 2, 2014I 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.

Arabic To Roman Numeral Converter
Sep 12, 2014I 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");
