LongSupplier represents a supplier of long-valued results. This is the long-producing primitive specialization of Supplier.
The following example shows how to use LongSupplier
.
import java.util.function.LongSupplier; /* w w w . j av a 2 s . co m*/ public class Main { public static void main(String[] args) { LongSupplier i = () -> Long.MAX_VALUE; System.out.println(i.getAsLong()); } }
The code above generates the following result.
