To determine the class(es) referred to, the Java virtual machine invokes the loadClass method of the class loader that originally created the class. For example, an application could create a network class loader to download class files from a server.
Horses love to eat grass and plant materials. They eat what are known as legumes. The best known legumes are peas, beans, peanuts, lentils, alfalfa and carob. Horse owners usually feed their horses a mixture of grass and legumes which is called hay.
ALL horses NEED to eat hay as the base of their diet (unless they are out on a pasture where they can eat lots of fresh grass). They may or may not need grain based on the factors this person listed (climate, workload, whether the horse is an easy keeper or not).
