Convert from int to char

Hi,
How can I convert from an int to char?

The challange is to convert from int to String without using any API or automatic conversionWoah, what a challenge ! Why ?
Anyway, what about a recursive call and switch statement. Something likepublic String intToString(int n) {
    if(n<0) {
        return "-"+intToString(-n);
    if(n<10) {
        return getStringDigit(n);
    else {
        return intToString(n/10) + getStringDigit(n%10);
private String getStringDigit(int n) {
    switch(n) {
        case 0:
            return "0";
        // etc.
}

Checking wheter is "int" or "String"

Hi..
I would like to know is there a way to know if an attribute type is int or String while executing my application.
I heard "why do you wanna know?", that is just because this attribute belongs to another class and I'm gonna use it in every class. Later it's possible this attribute will change it's type so I would provide some if statements now, for don't have trouble with it later.
Thanks in advance.

Thanks in advance.What do you mean by "attribute type"?
How will it change its type? - if you change a variable type from int to String or vice versa, then code that uses it won't compile anyway.
Are you doing something unusual with reflection? If you are, could you post some code that demostrates what you actually want to do?

Is there a way to convert an int to string

My example
String s = "";
int one = 1;
int two = 2;
s = one - two;
I tried somethings but cannot seem to get by this one.
Thanks in advance
Adam

What are you trying to do? Subtract int two from int one and get the result as a String? That's what it looks like you're trying to do, try this...
String s = "";
int one = 1;
int two = 2;
s = (new Integer(one - two)).toString();This will set s equals to the String 1.

Problems with indexOf reading from an updating string

String[][] shapeArray = new String[5][2];
int isCol;
int isCom;
String outputsub1 = finoutput; // finoutput is holding text imported from a file
String outputsub2;
for (int y = 0; y < 2; y++)
     for (int x = 0; x < 5; x++)
          isCol = outputsub1.indexOf(":");
               isCom = outputsub1.indexOf(",");
              if (x == 4 && y == 1)
               shapeArray[x][y] = outputsub1.substring((isCol+2));
          else
                   shapeArray[x][y] = outputsub1.substring((isCol+2),isCom);
              outputsub2 = outputsub1.substring(isCom+2);
              outputsub1 = (outputsub2);
}the text imported looks like this...
Shape: Circle, Position: 100, 250, Size: 130, 130, Colour: Blue, Fill: yes
Shape: Rectangle, Position: 300, 250, Size: 110, 110, Colour: Red, Fill: no
i would use a string tokeniser, but i need to use this method. im trying to shorten the string each time so that the indexOf will find the next ":" each time. However when i try and update the string holding the updated data (outputsub1) i get the following error:
java.lang.StringindexOutOfBoundsException: String index out of range: -8
at java.lang.String.substring(String.java:144)
at ReadFile.init(ReadFile.java:52)
at sun.applet.AppletPanel.run(AppletPanel.java:353)
at java.lang.Thread.run(Thread.java:534)
i hope that makes sense to someone, it only occurs when i add the line..
outputsub1 = (outputsub2);
and works fine when i comment it out (although doesnt give the right response obviously.)
thankyou for any help you can offer

String index out of range: -8 simply means that you try to access the String at position "-8", which obviously makes no sense. There must be some mistake either in your code or your algorithm. Keep in mind that indexOf returns -1 in case the argument wasn't found - maybe that's the reason for that error.

Convert an int in string

I wrote this code to convert an int in string but is failed.
Someone might help me. thanks
String UID="select max(right(CodiceUtente,4)) from Utenti";
     ResultSet rs=st.executeQuery(UID);
     int massimo=rs.getInt("CodiceUtente") + 1;
          //massimo deve essere trasformato in una stringa. Come si fa?
     String maxim =toString();
my email is [email protected]

Try this one: String maxim = toString(massimo).
Find out more from the API (hope it accepts this long
URL that should point directly to the right place) :

BIgMAth from base64 encoded string

I'm trying to create a BigInteger from a source that is a base64 encoded string. The BigInteger seems to only support radix up to 36. I have a couple of questions.
1) Why does BigInteger not support higher radix?
2) Anyone have any advice on how to manually make the BigInteger from a base64 string? Obviously I can change the encoding myself to a lower radix, but I thought someone might have a better idea?
Thanks,
Chad

Base64 is not a Radix in the sense of Decimal or Hex.
The javadoc for one of the BigInteger constructors -
BigInteger
public BigInteger(int signum,
                  byte[] magnitude)
    Translates the sign-magnitude representation of a BigInteger into a BigInteger. The sign is represented as an integer signum value: -1 for negative, 0 for zero, or 1 for positive. The magnitude is a byte array in big-endian byte-order: the most significant byte is in the zeroth element. A zero-length magnitude array is permissible, and will result inin a BigInteger value of 0, whether signum is -1, 0 or 1.
    Parameters:
        signum - signum of the number (-1 for negative, 0 for zero, 1 for positive).
        magnitude - big-endian binary representation of the magnitude of the number.
    Throws:
        NumberFormatException - signum is not one of the three legal values (-1, 0, and 1), or signum is 0 and magnitude contains one or more non-zero bytes.so to force to be positive make the first parameter a 1 .

How can I convert a string to Int & and an Int to String ?
Say I've
String abc="234"
and I want the "int" value of "abc", how do I do it ?
Pl. help.

String.valueOf(int) takes an int and returns a string.
Integer.parseInt(str) takes a string, returns an int.
For all the others long, double, hex etc. RTFM :)
