We have been using this language in many applications; [...]
Code Generation in Application Development
Till date there would have been hundreds of thousands of lines of code written in each programming language. Every new application getting developed adds thousands of lines of code to this code pool. But this code is not for free, it involves huge amount of money. There are many techniques to reduce the application development [...]
What We Mostly Use in Java
Ok, I haven’t written any tool to scan entire worlds Java code to find out these syntax elements.

Google Collection Types
Google Collections provide additional collection types to offer additional but common features. These advanced types are derived from Java Collection types, hence they continue to offer the features of underlying Java type. In addition to that there are many additional features encapsulated in these new types, so that we can directly use them instead of [...]
