DoubleSupplier Interface is a part of the java.util.function package which is introduced in Java 8. It is an in-built Functional Interface. This function doesn’t expect any input but produces a double-valued output. In this post, we are going to see several implementations of DoubleSupplier Interface by using different examples.

Look at DoubleSupplier Javadoc description below:
As you’ve seen in the above screenshot, DoubleSupplier Interface contains only the following function:
double getAsDouble();
This method represents a supplier of double-valued results. This is the
double-producing primitive specialization of Supplier.
Example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | import java.util.function.DoubleSupplier; public class DoubleSupplierInterfaceJava8Example1 { public static void main(String[] args) { System.out.println("DoubleSupplier Interface - Example\n"); DoubleSupplier doubleSupplierObj = () - > (Math.random()) / 2; System.out.println("Result: " + doubleSupplierObj.getAsDouble()); } } |
