How to get part of a String?
I have following code which produces the required output:
Code:
String fileNameWithExt = "interface_for_database_18sep07.txt"; String fileName = fileNameWithExt.substring(0, 30); System.out.println(fileName);
Output:

Code:
interface_for_database_18sep07
The point is, I have mentioned the ending index of the string in substring(…) method. How can I make it a bit flexible because the filename can change.

java.lang.StackOverflowError

I have written a recursive module and I get java.lang.StackOverflowError. I got some output before this exception. I want to know after how much iteration this exception is raised. Wont Java compiler identify this recursive statement at compile time?

Code:
String fileNameWithExt = "interface_for_database_18sep07.txt"; int dot = fileNameWithExt.indexOf("."); String fileName = fileNameWithExt.substring(0, dot); System.out.println(fileName);

Depends on how you have set up your method. I would try to use some println statements to track what you think should be happening as it recurses.

Probably not; depends on what you wrote. Your code can compile okay and create all kinds of problems at runtime.
