How to convert the String "1+1==2" into the boolean true?

Hi folks!
I need your help...
In a Java program, I have a String such as
String str="1+1==2";
and I want to know if the content of this String is true or not.
How to get the answer in a boolean b?
I already know that
boolean b=Boolean.valueOf(str).booleanValue();
doesn't work (b contains false);
whereas when I try
boolean b=Boolean.valueOf("true").booleanValue();
it perfectly works (b is true).
Would you be so kind as to solve my problem?
Thanks ;)

Hi folks!

How to get the answer in a boolean b?How can the content of a String ever be a boolean ? and we all know that one...
If he were to revise his orginal requirement things would not be so
difficult for him.
"1+1==2" and "2*12-2*10==2" have one thing in common. They both check if the
RHS is equal to 2 or not...and THAT is a boolean.
And if that is a String it takes no genius to figure out how to
get a number out of them.
What's the problem with getting his boolean result.

    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.

  • 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.

    Do you mean "two different layers" as in separate JVMs or "two different layers" as in functional areas running within the same JVM.
    In either case, if the first class is actually semantically and functionally the same as the second (and they are always intended to be the same) then import and and use the first class in place of the second. That's beyond any question of how to get the data of the first into the second if and when you need to.
    Once you make the breakthrough and use one class instead of two I'd guess that almost solves your problem. But if you want to describe your architecture a little that would help others pin down want you're trying to do.

    So it seems from reading the COMMAND manual that my first issue is that I used a 16GB SD card, and the manual says it will only recogize up to a 2GB SD card. I did use my MB Air's SD card slot and crated a folder and dragged the music files to it, then to the card. So I am going to get a 2GB card and try that next. Otherwise just stick with the iPOD connected. At least that is 8GB

    If your question is about the format spreadsheet, it is not possible from Reports Builder :

    It is not possible to generate spreadsheet output directly from Reports Builder. Instead, on the command line, you can run the report using rwrun or Reports Server clients (rwservlet, rwclient, rwcgi), with DESFORMAT=SPREADSHEET. You cannot store DESFORMAT=SPREADSHEET as a system parameter value in the report definition (.rdf file).

    If you're able to read frequency as X pulses/sec(?) that seems to convert RPM as follows:
    X (pulse/sec) * 1/500 (rev/pulse) * 60 (sec/min) = X * 60/500 RPM (???)
