Binary operator

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)
