IntFunction
represents a function that accepts an int-valued argument
and produces a result.
This is the int-consuming primitive specialization for Function
.
The following example shows how to use IntFunction
.
import java.util.function.IntFunction; // ww w .jav a 2 s . c o m public class Main { public static void main(String[] args) { IntFunction<String> i = (x)->Integer.toString(x); System.out.println(i.apply(3).length()); } }
The code above generates the following result.
