In this tutorial, we’ll look at some ways to check whether an integer exists within a given range. We’ll do that using operators as well as several utility classes.
Before we use any of these methods, we have to be clear about what kind of rangewe’re talking about. We’ll focus on these four bounded range types throughout this tutorial: 1. closed range – includes its lower and upper bounds 2. open range – excludes its lower and upper bounds 3. left-open right-closed range – includes its upper bound and excludes...
Our goal is to determine whether a number is between a given lower and upper bound. We’ll start by checking for this using basic Java operators. Let’s define a class that does this check for all four kinds of ranges: Here, by changing the operators to include or exclude the bounds, we can tune the interval to be open, closed, or half-open. Let’s te...
As an alternative to using Java operators, we can also use utility classes that represent ranges. The primary benefit to using pre-defined classes is that range classes offer out-of-the-box implementations for some or all the range types described above. Additionally, we can configure a range object with our defined bounds and reuse the object in o...
In this article, we learned how to use basic operators and range classes to check whether an integer falls within a given range. We also explored the pros and cons of the various approaches.
Nov 24, 2022 · Solution. In short, I ended up adding the following Java between method to my MathUtils class: public static boolean between(int i, int minValueInclusive, int maxValueInclusive) { if (i >= minValueInclusive && i <= maxValueInclusive) return true; else. return false; }
We can check whether an integer exists in a range in Java using conditional statements with the lower and upper bounds of the range. To check whether an integer exists in a range, we can use the following steps: Define the range (start and end) values. Compare the integer to the range start and end values.
How to Check Whether an Integer Exists in a Range with Java - Through Java. 1. Overview. We will learn how to check if a number is within a specific range in this tutorial. We will use operators and utility classes to do this. 2. Range Types.
Oct 28, 2022 · In java.lang.Math you have a method isBetween (int toCheck, int from, int to), which is defined as. public static boolean isBetween(int toCheck, int from, int to){ // eventually validate the range return from <= toCheck && toCheck <= to; }
