Java 8 for Experienced Developers: Lambdas, Stream API & Beyond

## `BinaryOperator<T>`
`BinaryOperator<T>` is a functional interface that inherits from `BiFunction<T, T, T>` interface. The `BinaryOperator<T>` interface takes only one parameter as compared to `BiFunction<T, T, T>`, which takes three parameters(two operands type and one result type).

Both the input objects and the result are of the same type in `BinaryOperator<T>`.

Below are the few interfaces that come under the `BinaryOperator<T>` category.
|     |     |    |
| --- | --- | --- |
|`BinaryOperator<T>`     |Represents an operation upon two operands of the same type, producing a result of the same type as the operands  (reference type)     |  	`T apply(T t, T u)`
|`DoubleBinaryOperator`     |Accepts two double-value operands and produces a double-value result     |  `double applyAsDouble(double left, double right)`
|`IntBinaryOperator`     |Accepts two int-value operands and produces an int-value result     |  `int applyAsInt(int left, int right)`
|`LongBinaryOperator`     |Accepts two long-value operands and produces a long-value result.     |  `applyAsLong(long left, long right)`
