Kotlin: Get Values of a Range in another Range Ask Question Asked 1 year, 10 months ago Modified 1 year, 10 months ago Viewed 1k times 1 Hello im trying to write a function that compares to ranges and returns the value of the first range in the second. I found out that Kotlin has ranges and I can use them as follows: 1.n But this is an inclusive range which includes 1 and n. The boilerplate code present in Java is also greatly reduced. I want to create a range from 1 to n where n is excluded. Since it is compiled the same way as Java, its functions and methods ensure your code is more efficient. Kotlin provides easier ways to perform specific actions. ![]() Similarly we can create character ranges such as ‘A’.’D’ which will create a series of values A, B, C, D. For example a range of 1.5 would create a series of values 1, 2, 3, 4, 5. Most of these solutions aim to make development easier and faster. With the help of ranges in Kotlin we can easily create a list of sequence by specifying starting and ending value. In such way, you can replace the - with =>, which looks like scala.Since we’re defining our custom range, CustomColor class must implement the rangeTo method. Kotlin provides a wide range of solutions. ![]() If you're happy, you can rename the minus function to compareTo and return 0. You can put the whole expression in the second part, which is OK but seems like unnecessary duplication. There are three ways for creating Range in Kotlin Using (.) operator Using rangeTo () function Using downTo () function (. The start and stop are inclusive in the Range and the value of step is by default 1. I tried to find an unbounded range comparison, but couldn't make this work either? Is it possible to write this as an unbounded range? // trying to get an unbounded range - doesn't compile The range in Kotlin consists of a start, a stop, and the step. I'm trying to use the WHEN clause with a > or = >) in a comparison to enable this? val foo = 2 Simply, a when statement in Kotlin looks at the 'case', and if it is a range, it sees if the variable is in that range, but if it isn't, it looks to see if the case is of the same type of the variable, and if it isn't, you get a syntax error. ![]()
