How to convert a String Variable to a Number and retain decimal place

Hello!
Here is my problem!
I am receiving information from a source that I cannot control. It is sending me Numbers in to form of strings.
Ex: 12,200.49
I have tried usingval() but only get " 12 " because it stops when it see a comma or period.
I have also tried using Replace() to remove the comma and period, but then my number grows, because the last two digits are now part of the number and no longer behind a decimal point.
Here is some example code
<cfset Price = "12,200.49">
<cfoutput>
#val(Price)#
<cfset Price = '#Replace(Price,",","","ALL")#'>
<BR />
#val(Price)#
<cfset Price = '#Replace(Price,".","","ALL")#'>
<BR />
#val(Price)#
<cfset Price = #NumberFormat(Price, "_____.__")#>
<BR />
FINISHED WITH #Price#
</cfoutput>
The output of the above code is this:
12
12200
1220049
FINISHED WITH 1220049.00
So, you can see that 12,200.49 is now 1,220,049.00 because the two digits where added.
What I would like to finish with is a String "12,200.49" that is now a Number like this $12,200.49
Please help!!!

HI
try this
<cfoutput>
<cfset t="12,200.49">
<cfset Price = Replace(t,",","","ALL")>
#DollarFormat(Price )#
</cfoutput>

How to convert a String variable as class name and method name?

i have two classes
class Student
public String insertStudent(String sname)
{ return("Student has been inserted "); }
class Teacher
public String execute(String methodName, String className)
{ //return statement of the method 'insertStudent' in the class 'Student'; }
}Now, i have a class with the main method. Here, i would like to call the method *'insertStudent'* of class *'Student'*
using the method *'execute'* of class *'Teacher',* passing the method-name and the class-name (viz. insertStudent, Student) as the
String parameter.
Can anyone please help me out. Thanks

You should have just added that as a comment on your [initial posting|http://forums.sun.com/thread.jspa?threadID=5334953] instead of starting a new thread.

Why oh why? What do you want to achieve?
Let me tell you: there is a way to do what you try to do, but it's not recommended and should be used only very sparingly. Especially not in anything like your code, that resembles normal business logic (as opposed to an application framework such as Spring, for example).
Can you explain what exactly you want to do with that? Why should a Teacher be able to call any random method ony any other class. And what good would that do?

In your post you ask how to convert a string value to a date. The value returned from the Get-AdUser is already a date. It does not need to be converted.
Bill has sshown one way to convert a date to a string and there are other methods. You need to clarify your question.
If you are really trying ot convert strings to dates then you can start with this:
[datetime]'01/21/1965 13:33:23'
Most date strings aer autodetected by the class.
¯\_(ツ)_/¯

How to convert a String to an Icon

Hello,
I'm trying to figure out how to convert a String (specifically one letter) to an Icon for a JTree. The program I am working on uses .png files for the icons at the moment, with each .png being a single uppercase letter. However, recent discussion has us wanting to change to something more dynamic, since we anticipate needing new letters in the near future.
My task is to modify the current codebase so that the Icons used to identify nodes in the tree are created from a Font within code, rather than reading in .png files. I have done some experimenting with creating a Label with just that String, setting the font and trying to extract the image using calls like createImage(int width, int height) and so on, but so far to no avail.
If I could figure out how to at least convert the String to an image, I could probably make it work (since I can play around with creating an ImageIcon with that image). Thanks in advance for any help.
Allan

Here is some quick and dirty code:
import java.awt.*;
import javax.swing.*;
public class BasicIcon implements Icon {
    private String text;
    public BasicIcon(String text) {
        this.text = text;
    public int getIconWidth() {
        return 16;
    public int getIconHeight() {
        return 16;
    public void paintIcon(Component c, Graphics g, int x, int y) {
        Color old = g.getColor();
        g.setColor(c.getForeground());
        g.drawString(text, x, y+13);
        g.setColor(old);
    public static void main(String[] args) {
        JPanel cp = new JPanel();
        for (char ch = 'A'; ch < 'F'; ++ch) {
            cp.add(new JButton("letter " + ch, new BasicIcon(String.valueOf(ch))));
        JFrame f = new JFrame("BasicIcon");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setContentPane(cp);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
}One thing that could be improved is the vertical positioning of the letter in the Icon.
The x,y values passed into paintIcon are the upper-left hand corner of the icon,
but the y value needed by drawString is the position of the String's baseline.
To do it right, use one of Font's getLineMetrics methods and play around with ascent.

How to convert EBCDIC String in hex to unicode?

How do I convert, for example, "C1C2C3C4C5" (EBCDIC in hex) to "ABCDE"? The input and output types are both String. Thanks in advance!

1. Create a String of 256 characters, where the index corresponds to the ASCII character (e.g. character at index 193 (0xC1) would be 'A').
2. Parse your input string two characters at a time using Integer.parseInt(s, 16) to convert the two digits to a number, and use the resulting number to get the equivalent ASCII character from the translation string in step 1, which can be appended to your output.

How to swap two string variables without using a 3rd
variable?
Something like this.
Append A with B (so A equals "aabb")
Set B equal to a substring of A starting with the first character and ending at A's length minus B's length. (So B equals "aa")
Set A equal to a substring of A starting from B's length and ending at the end of A. (So A equals "bb")

How to get STPOV structure values using BOM number and Plant number

hello All,
could you please help me out
'How to get STPOV structure values using BOM number and Plant number'
is there any function module where can i give input as bom and plant number .
waiting for your response.
regards
srinivas

I did a quick where-used lookup in SE11 on the structure STPOV in function module interfaces and came up with the following:
Function Module                             Short Description
CK_F_TOTALCOST_COMPUTE
CS_ALT_SELECT_COUPLED_PRODUCT
CS_WHERE_USED_CLA                Bills of material; class use
CS_WHERE_USED_CLA_ANY        Bills of material; direct class use or via other class
CS_WHERE_USED_CLA_VIA_CLA        Bills of material; class use via classes
CS_WHERE_USED_COP
CS_WHERE_USED_DOC                Bills of material; document use
CS_WHERE_USED_DOC_ANY:Bills of material; direct and (indirectly) document use via
CS_WHERE_USED_DOC_VIA_CLA        Bills of material; document use via classes
CS_WHERE_USED_KNO                Bills of material; use object dependency
CS_WHERE_USED_MAT                Bills of material; where-used list
CS_WHERE_USED_MAT_ANY:Bills of material; where-used list as article or class item
CS_WHERE_USED_MAT_VIA_CLA        Bills of material; where-used list via classes
EXIT_SAPMC29M_001                BOM; Article Where-Used List
It appears that this structure is primarily used for where-used look-ups for components within the BOM. I don't know if any of these are what you're in need of.
Hope this helps,
