The LongToDoubleFunction is a functional interface in Java that belongs to the java.util.function package. It represents a function that accepts a long value as an argument and produces a result of type double. This functional interface is typically used in scenarios where we want to perform an operation that converts a long input into a […]

The LongSupplier is a functional interface in Java that is part of the java.util.function package. It represents a function that supplies a long-valued result. This interface is particularly useful when we need to generate or provide long values without requiring input arguments. Since LongSupplier is a functional interface, it has a single abstract method: long […]

In Java, the LongPredicate is a functional interface introduced in Java 8 as part of the java.util.function package. It represents a predicate (a boolean-valued function) that takes a single long value as its input argument. The key method in LongPredicate is: boolean test(long value); Here’s how we can use the LongPredicate functional interface: Example Usage […]

The LongFunction is a functional interface in Java present in the java.util.function package. It represents a function that takes a long as input and produces a result of a specified type. Key points about LongFunction: 1. Single Abstract Method: It contains a single abstract method: R apply(long value); Here, R is the return type of […]

The LongConsumer functional interface in Java is part of the java.util.function package and is commonly used for defining operations that consume a single long-valued argument and return no result. It’s a specialization of Consumer for the long primitive type. The key method in LongConsumer is: void accept(long value); Using LongConsumer Here’s how we can use […]

The LongBinaryOperator is a functional interface in Java that is part of the java.util.function package, introduced in Java 8. It represents an operation upon two long values that produces a single long result. This can be thought of as a primitive specialization of the BinaryOperator interface for long types. Key Features of LongBinaryOperator: It’s a […]
