Team MAST's video: Return a Random item from a list in Java Team MAST

You will learn 3 methods on how to generate a random number and based on that you will see how to return a random item from a list in Java. In practice, the java.util.Random class is often preferable to java.lang.Math.random(). However, if multiple threads use same instance of Random, it kills performance because all threads keep accessing the same random generator method. Creating a new Random object each time you want a random number is a bad practice. You must create once and re-use it. Since JDK 1.7 you could uise ThreadLocalRandom class which will generate a single Random instance per thread. For popular videos: 1.
