Building fast and highly performant data science applications requires an intimate knowledge of how data can be organized in a computer and how to efficiently perform operations such as sorting, ...

Here's what I've learned over 20 years of working with both C++ and Java (and more years before that with C++): As a rule of thumb, when you convert optimized C++ to Java, the code is about 3x slower.

Java programmers use data structures to store and organize data, and we use algorithms to manipulate the data in those structures. The more you understand about data structures and algorithms, and how ...
