Make Array of int's from a String

Hi,
Trying to transform a String into an array of ints. The following works, but seems a little longwinded for what must be quite a common function - specifically line 9 in the code (turning a char into an int). Can anyone suggest an easier way?
public class IntArray {
    public static void main( String[] args ) {
        if ( args.length == 1 ) {
            String s = args[ 0 ] ;
            int sLength = s.length() ;
            int[] argIntArray = new int[ sLength ] ;
            for ( int j = 0 ; j < s.length() ; j++ ) {
                // This line ...
                argIntArray [ j ] = Integer.parseInt( s.charAt( j ) + "" );
            for ( int j = 0 ; j < argIntArray.length ; j++ ) {
                System.out.println( argIntArray[ j ] );
        } else {
            System.out.print( "Please enter an int" );
}Thanks,
Rich

I'm not sure how common it is, but since you are assuming that the input is a String that represents an int...
public class IntArray {
     public static void main( String[] args ) {
          if ( args.length == 1 ) {
               String s = args[ 0 ] ;
               int sLength = s.length() ;
               int[] argIntArray = new int[ sLength ] ;
               for ( int j = 0 ; j < s.length() ; j++ ) {
                    // This line ...
                    argIntArray [ j ] = s.charAt( j ) - '0' ;
                    //I suggest checking for <0 or >9
               for ( int j = 0 ; j < argIntArray.length ; j++ ) {
                    System.out.println( argIntArray[ j ] );
          } else {
               System.out.print( "Please enter an int" );

Dynamic Variable name (for int/long) from a String variable

Hi,
I want to give a int/long variable name from a String.
for ex.
String str = lookup + "Id";
lookup is a String variable coming from XML. Now, for instance lookup="name". So str = "nameId".
Now I want to create a int/long variable by nameId.
Could anybody tell me the way how to do. Please don't tell to use MAP.
Edited by: Shah on Dec 5, 2007 3:26 PM

Well you can't. Use a Map.
The compiler translates variable names into slot numbers, either within an object or withing the local "stack frame" and these slot numbers are assigned names at compile time. No new slots can be created at run time. Java is not Basic.
Reflection allows you to find existing field names and methods (not local variables), so it's possible to map, for example, XML attribute names to field names or setters in an object but the names have to be known at compile time.

Extract int from a string

Hi,
I am curious if there is an easy way to extract an int value from a String.
For example, "Rb23" to get 23. The length of the part in front of the integer is variable.
Thanks

this seems to work:
public int extract(String s) {
     String result = "";
     char c[] = s.toCharArray();
     int j = c.length-1;
     if (!Character.isDigit(c[j])) {
          return 0;
     do {
          result+=c[j--];
     } while (j > 0 && Character.isDigit(c[j]));
     return Integer.parseInt(new StringBuffer(result).reverse().toString());
}it will return 0 if no numbers are found at the end of the string

How to convert String array into int.

how do i convert words which is a string array into int type. i kno string can be converted into int using interger.parseint. but wat abt string arrays??? plz help me out with the above code.

i did tht its still giving the same errorFor Heaven's sake, what about taking a second to try to understand the code you're copying first? If you really can't fix the error yourself, you have a more serious problem than just convertingStrings to ints.
And if you want { "1", "2", "3" } to be 123:
StringBuffer b = new StringBuffer();
for (int i = 0; i < array.length; i++) {
b.append(array);
int result = Integer.parseIn(b.toString());

How do I make a Datagram Packet from a String?

I am looking to make a Datagram Packet from a string. If I send a command to a server that allows remote connections via UDP, such as "restart" it will restart the server. I can accomplish this easily through the fput() method of PHP.
I want a Java version of my utility, and am using the DatagramSocket and DatagramPacket classes. I see that I need to make a byte array and put it inside a DatagramPacket. How would I go about putting the string "restart" into a byte array?
Thanks,

Use the following code to send a Datagram:-
import java.io.*;
import java.net.*;
// This class sends the specified text as a datagram to port 6010 of the
// specified host.
public class UDPSend {
    static final int port = 6010;
    public static void main(String args[]) throws Exception {
        if (args.length != 2) {
            System.out.println("Usage: java UDPSend <hostname> <message>");
            System.exit(0);
        // Get the internet address of the specified host
        InetAddress address = InetAddress.getByName(args[0]);
        // Convert the message to an array of bytes
        int msglen = args[1].length();
        byte[] message = new byte[msglen];
        args[1].getBytes(0, msglen, message, 0);
        // Initilize the packet with data and address
        DatagramPacket packet = new DatagramPacket(message, msglen,
                               address, port);
        // Create a socket, and send the packet through it.
        DatagramSocket socket = new DatagramSocket();
        socket.send(packet);
}This uses argments, if you want a string change the code accordingly.

How can i store values from my String into Array

Hi guys
i wants to store all the values from my string into an array,,,, after converting them into intergers,,,, how i can do this becs i have a peice of code which just give me a value of a character at time,,,,charat(2)...BUT i want to the values from String to store in an Array
here is my peice of code which i m using for 1 char at time
int[] ExampleArray2 = new int[24];
String tempci = "Battle of Midway";
for(int i=0;i>=tempci.length();i++)
int ascii = tempci.charAt(i); //Get ascii value for the first character.

public class d1
     public static final void main( String args[] )
          int[] ExampleArray2 = new int[24];
          String tempci = "Battle of Midway";
          for(int i=0;i<tempci.length();i++)
               int ascii = tempci.charAt(i);

Getting int values from a char array

Hi,
I need to make a fast program which reads lots of data from files and process them. I need to interpret these data as int's. To be more efficient and avoid to make a lot of disk access, I allocate in memory buffers part of the data, then process it and then allocate new data. The problem is that if I want to allocate data in memory buffers, all the methods that enables me to do that receceive as a parameter only a an array of chars, and as I have mentioned I need to interpret the data as a 4 bytes int. The static methods of Array to get the int value from a position ar not useful because the onlye get the int value of the indexed byte (or char); this method doesn't take 4 bytes from the index to build an int.
My question is: is there any way to build an int from 4 bytes? or can I get the int's in this way directly from the buffer?
Thank you,

Isn't this one of the prime examples of using java.io.DataOutputStream and java.io.DataInputStream?

Scan arrays from binary string

I have TCP connection that is sending a great number of fixed size arrays that I need to convert. Is there a simpler way to do that than the one I have attached?
Attachments:
Scan from binary string.vi ‏16 KB

Sorry, I didn't write my question clear enough.
I know how to do TCP data transfer. I also know how to unflatten the binary string back to data, but I was hoping there was a clearer way to do it than the way I suggested. For scalar values one can make a cluster containing the data in the binary string and only one "unflatten from string" is needed.
However, if the binary string is composed of arrays (even though they are fixed in size) I need one unflatten string for each array. In my case I have many small arrays. The attached example with only three arrays was only to illustrate what I wanted to do.
I have now found a way using a cluster of clusters. I don't know if this is the ideal way of doing this, but it works, and when enabling "view cluster as icon" I can make the code much more compact and easier to read

Getting one character at a certain position from a string array

How to dynamically create a JSF dataTable from a String[][] array

Hi, I�m developing an application that uses columns, rows and data instead of any other attributes, so I got from a database Resultset a String[] array with the rows headers, other String[] array with the columns headers, and a String[][] array with the information between every row[] and column[] header al this String arrays depend on a method that receives the group title as a parameter so they are dynamically created, anyway I can display this information in a jsp page but I don�t know how to display this information in a JSF dataTable.
Does anybody knows how I could do this? and which is the proper way to create a dynamically rows and columns dataTable?

But I cant write like this
Container String +"Container" = new Container();What's the best way to solve this..You want the variable names for those Containers to be based off the Strings? Is that what you mean? Why do you want/need to do that?
The go-to solution for stuff like this is to use a Map of String, Container pairs. But why over complicate your program with stuff you probably don't really need?
