Log4J is a really nice Library that aims to facilitate outputting debugging information, but also relevant data, in Java applications. It is highly configurable, using both Categories and Class-Based rules, so that developers can narrow down the problems very well when debugging applications.

I was coding a project that used arrays when the lack of a standard foreach in C/C++ got to me. So, I coded this little function to help me. It applies a function that returns int to each element of the array.

The snippet shows how to use it.

This simple function simply removes the character at the given index from a string.

Adds any character at the given index of a string.

NOTE: Count starts from 0

This function simply splits a file based on the splitter supplied and returns an array with the values. It's pretty much like the file() function. This script could be helpful in section editings.
