![]() ![]() You can iterate over each element of a List, but how would you iterate over each element of an integer? I'm assuming you want to do a certain action totalTime number of times. You're trying to iterate over a numeric value (in this case, totalTime, which is a Long). Since you're not using the finalPrice variable, I'm assuming you wanted to use this instead. You're not declaring the finalFee variable, thus the code will raise an Since a Long type in Kotlin stores a integer up to 9,223,372,036,854,775,807 and no soul on Earth will use your service for that long (this represents 17 billion milleniums), you can just use an Int. You can measure it in minutes to simplify your calculation (since all time values are measured in minutes). We can have a simple example to see the syntax and overall implementation of a generator.Let's take a look at your getTime function: Property : done: Property is used to specify that function has completed yet or not.Property : Value: Property is the result of the expression.This keyword return the iterator object with the mentioned property. It also contains two property value and done. Here is one advantage of yield function it pauses the function execution then returns the iterator object again resume the function execution whenever next() method is called. ![]() Given below are the some of the examples showing iterator use: false or undefined exception will be thrown. ![]() If we try to return a non-object value, e.g. So, the next() method always has to return an object with its properties done and value.
