Hi Ranchers,

Please solve this problem.

String str="hello.hello1.hello2.jpg";

How to split this String to two parts like

Part 1:- hello.hello1.hello2
Part 2:- jpg

please solve this problem

lastIndexOf() would be helpful.

Please tell us what you have got so far. We don't simply give out answers to that sort of question.

I would say the problem is not well-defined. For example, what if the string was "hello.hello1.hello2.jpg.hello3"? What if it was "hello.hello1.hello2"? What if it were "JPG"?

Simply providing one example does NOT define the problem.

Here is the JavaDoc for the String class

Do you see any methods listed there that might solve your problem?

Hi all,

Finally I solve this problem.

String str="vivek.vivek1.vivek2.jpg";
String str1,str2;
int x=str.lastIndexOf(".");
str1=str.substring(0,x);
System.out.println(str1);
str2=str.substring(x+1);
System.out.println(str);

with regards,

I quote one case:

More precisely, what will x be in that case, and what will be the results?

i wont think it will cause any effect as you are using only lastIndexOf

[Rob Spoor]

And what does lastIndexOf return if there is not dot in the String? And what will that specific return value do with the calls to substring?

First check for indexOf(".") if it returns true then check for LastIndexOf(".")

[Rob Spoor]

Completely unnecessary. lastIndexOf and indexOf return the same value if there's no match. You just have to check for that value.
