Genetic algorithm with JAVA study materials??

Question

Someone please direct me where I can find some materials to study with, preferably JAVA.

In computer science and operations research, a genetic algorithm ( GA ) is a metaheuristic inspired by the process of natural selection that belongs to the larger class of evolutionary algorithms (EA). Genetic algorithms are commonly used to generate high-quality solutions to optimization and search problems by relying on bio-inspired operators such as mutation, crossover and selection .
