This course focuses on teaching learners how to refactor Java code to leverage the features of Java 8 effectively. By the end of the course, students will be able to refactor code to use Lambda expressions, Streams, and Collection methods. The teaching method involves live demonstrations, performance and readability comparisons, and a summary of findings. This course is intended for Java developers looking to enhance their coding skills and improve the performance and readability of their code using Java 8 features.
