[pearwarin]

Hi all,

I hv a problem about substring method, I want to seperate data that I hv already got from db. An example of data as below message.

Data:
pic1.jpg,read1.pdf,abc.jpg,you_to_me.txt,

After I received data from db, I would like to delimited each file name by "," (comma) then displays as the below expected result

Expected result:
tmp1 = pic.jpg
tmp2= read.pdf
tmp3 = abc.jpg
tmp4= you_to_me.txt

Pls kindly help me. thank you very much

your using the wrong method. Use the split method.

example:

String[] splitData;
String data = "data1,data2,data3,data4";

splitData = data.split(",");

create an array variable that will hold the deliminated data. Then when u need the data you simply use it like this.

for (int i=0; i <= splitData.lenght;i++)
{
System.out.println(splitData[i]);
}

Hope that helps.

Thank you very much "Major" but I hv another problem, I cannot this method because there is a variable of data. I mean simetime my data has 4 filenames somtime 10 or more, it is not stable if I use String array I will seperate only 4 filenames....
can i specific size of array?

The Scanner class will create an array of all of the tokens - dynamically, as many elements as there are tokens. I believe that split() will do the same.

hi pearwarin, u dont need to set how many array u need in advance, u just decalre an instance of an array variable and not set it size, the split method will then allocate the size. The scanner class is also an option as mentioned by nspils, but it is available for java 5 i believe.
