J2ME Split String code segment

Most of you who are used to the split() functionality may miss it a lot when moving on to J2ME. So, here is a code segment which I had used to acchive similar functionality using J2ME methods.

public String[] split(String str, String delimiter){

//Iterate through the text to get the count of occurences
//This is done since we do not know how many times the
//delimitter occurs in the given string
//--------------------------------------------------//

int delimiterCount=0;
int index;
String tmpStr=str;

String[] splittedList;

while((index=tmpStr.indexOf(delimiter))!=-1){

tmpStr=tmpStr.substring(index+delimiter.length());
delimiterCount++;
}

splittedList=new String[delimiterCount];

/*-----------------------------------------------*/


/*-----------------------------------------------*/


//-----------------------------------------------//
index=0;
int counter=0;
tmpStr=str;


while((index=tmpStr.indexOf(delimiter))!=-1){


int nextIndex=tmpStr.indexOf(delimiter, index+1);

if(nextIndex!=-1){
splittedList[counter++]=tmpStr.substring(index+delimiter.length(), nextIndex);
tmpStr=tmpStr.substring(nextIndex);

}else{
splittedList[counter++]=tmpStr.substring(index+delimiter.length());
tmpStr=tmpStr.substring(index+1);
}
}

return splittedList;
}

Happy coding !!!!

We can also use this code.


private int[] setRule(String ruleId){
String regRule = getRule(ruleId);
char[] charRule = regRule.toCharArray();
int[] arrayRule = new int[2];
StringBuffer bufRule = new StringBuffer();
int m = 0;
for (int i = 0; i < charRule.length; i++) {
if (":".indexOf(charRule[i]) != -1) {
arrayRule[m] = Integer.parseInt(bufRule.toString());
bufRule.setLength(0);
m++;
} else {
bufRule.append(charRule[i]);
}
}
arrayRule[m] = Integer.parseInt(bufRule.toString());
return arrayRule;
}

Hi all,
First thanks for the code
the Java Split() function accepts regular expression as input
If we want to split "foo.mas.kjh.lok" with "." we should call it as "\\."

But if we give ("\\.") as delimeter in j2me result wont be same. Can any one suggest how can we achieve same behavior in J2me
Please suggest

Thanks,
Chandu

Hi Chandra,

Yes, that may be a feature of Java SE which is not available on J2ME. I don't think this will work in my code since I use a different logic to split the strings. If you are using my code, then I recommend you to set the delimiter as "." only.
Hope that helps.

Encrypt and Decrypt Images Using Java

Hi, Most of you would find it useful to Encrypt a special picture of yours such that only you can view it. By using JCE(Java Cryptography Extension) classes, this becomes very simple. As I have already done before using Java to encrypt a String is very simple. If you are new to this, please read the article which I had already posted named "Java Encryption and Decryption" at "http://ruchiram4.blogspot.com/2009/04/java-encryption-and-decryption.html" Also, you need to have a basic understanding of Java IO. If you are new, it is better to read the Sun Java tutorial on IO. Before we move on, lets recall the basic steps in Encrypting plaintext. 1. Creating an instance of "Cipher" object and setting the mode of Encryption (Eg: AES, DES) 2. Generating a key by using a KeyGenerator object. 3. Setting the mode of Cipher operation on the Cipher object. As we intent to Encrypt, we simply set it by setting a property of Cipher object by calling its "init"

Build your own Network sniffer

Image
Recently, I ve been developing a tool to monitor the Network Traffic as an assignment. Here, I wish to share my experience with all of you who are interested in building your own Sniffer. Prerequisites : Java Programming capability, Knowledge on OOP(Object Oriented Programming) basics My Environment: I used the libraries specified for Java which is widely available. I ran my application on Windows XP only. But the libraries can be easily integrated with Linux based systems. I used NetBeans 6.1 version for development activities. But any other java IDE would do In setting up the environment, first you need to download Jpcap jar found at http://sourceforge.net/projects/jpcap Once you download this, you have to add this to your NetBeans project. It can be done as follows. After adding the Jar file to the project, you need to download the WinPCap driver. It can be easily downloaded from http://www.winpcap.org/ It is required to get low level networking access regarding packets. As for

ASP Response.Write newline

Hi, all of you who have used ASP may have encountered situations where you require to write a text output to the screen. It can be easily done by using Response.Write("Hello world"); However, if you wish to append some more text to a newline, it would not work in the following ways. Response.Write("Hello world \n"); Response.Write("Good day."); The output of the above lines would be Hello world Good day. and NOT Hello world Good day. In order to overcome this, you can very simple place an html break tag inside the code. Response.Write("Hello world"); Response.Write("<br/>"); Response.Write("Good day."); The output would be the following. Hello world Good day. Cheers !!!
