Taking Values From a String

[naro pad]

I pass a String parameter where can has value of this type:

"2.ACSC344,5.ACSC345,8.ACSC456"

I want somehow to read from this String and save it to hashtable.When I find the number(before dot) to save it as the key and when finding the code(after dot)save as the value of the key and I want to loop until all are saved.How can I do that if it's possible?

Try using String's split() method.

Keep in mind that this method uses regular expression, and . is a special character. You'll need to escape it: "\\."

[Shashi Kala]

To escape dot why the need of two slash symbols(\\). Is using one slash is not enough??

Sorry in case if this question is silly.

[Rodrigo Lopes]

The slash is also a special character. Then you need two slashes to escape a slash

Thanks all of you for the replies...but because I'm a beginner can anyone provide me with an example or reference please?

[Rodrigo Lopes]

Have you already tried something, after those clues?

[Rob Spoor]

Like Rodrigo said, \ is a special character. The regular expression is just \. but you will need to escape that \ too.

Thanks a lot...It's working.I have do it like this:

Hashtable ht=new Hashtable();
        String preq=request.getParameter("preq");
        if(preq!=null){
           String[] items=preq.split(",");
           for(int j=0; j<items.length;j++){
                String tmp=items[j];
                String[] indiv=tmp.split("\\.");
                ht.put(indiv[0], indiv[1]);
                
           }
           
       }

String _kelime = "2.ACSC344,5.ACSC345,8.ACSC456";
int key = 0;
int value = 0;
boolean ayır = false;
Hashtable<String,String> _table = new Hashtable<String,String>();

for(int i = 0; i < _kelime.length(); i++){
if(".".equals(_kelime.charAt(i)+"")){

key =  i - 1;
}
if(",".equals(_kelime.charAt(i)+"")){
value =  i - 1 ;
ayır = true;
}else if(i  == _kelime.length() -1){
value =  i ;
ayır = true;
}else{
ayır = false;
}
if(ayır){
_table.put(_kelime.charAt(key)+"", _kelime.substring(key+2, value+1));
}

}
 
}

This one is also be the solution..

Welcome to JavaRanch, ibrahim uzan.

By the way: Most people would use a HashMap nowadays rather than Hashtable; it is more efficient.
