Therandommethod of theMathclass will return adoublevalue in a range from 0.0 (inclusive) to 1.0 (exclusive).Let’s see how we’d use it to get a random number in a given range defined byminandmax: int randomWith
Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on interfaces. It manages to add many of the features of functional languages wit...

By adjusting this bound, we control the range of potential outcomes. Here’s an example: import java.util.Random; public class RandomNumberGenerator { public static void main(String[] args) { int min = 1; int max = 10; Random random = new Random(); int value = random.nextInt(max -...

The way partitions are managed is that each partition is assigned a roughly equal slice out of the range of partition key values; therefore you are advised to choose a partition key which is relatively random or evenly-distributed. Otherwise, some partitions will see substantially more requests (...

Using n bits, we can represent any set made of the integers from the range [0,n): the ith bit is set to one if integer i is present in the set. Commodity processors use words of W=32 or W=64 bits. By combining many such words, we can support large values of n. Intersections,...
If a method call results in an exception, the caller must choose between handling or propagating the exception: Handling an exception means catching it, possibly performing some corrective, cleanup, or fallback action, and then proceeding normally so that the caller's own caller is shielded from...
