BinaryOperator Interface in Java
The BinaryOperator interface represents an operation upon two operands of the same type, producing a result of the same type as the operands.
Following are the methods −
| Modifier and Type | Method and Description |
|---|---|
| maxBy(Comparator<? super T> comparator) | Returns a BinaryOperator which returns the greater of two elements according to the specified Comparator. |
| minBy(Comparator<? super T> comparator) | Returns a BinaryOperator which returns the lesser of two elements according to the specified Comparator. |
Example
Let us now see an example −
import java.util.function.BinaryOperator;
public class Demo {
public static void main(String args[]) {
BinaryOperator<Integer>
operator = BinaryOperator
.maxBy(
(x, y) -> (x > y) ? 1 : ((x == y) ? 0 : -1));
System.out.println(operator.apply(120, 5));
}
}
Output
This will produce the following output −
120
Example
Let us now see another example −
import java.util.function.BinaryOperator;
public class Demo {
public static void main(String args[]) {
BinaryOperator<Integer> operator = (x, y) -> x * y;
System.out.println(operator.apply(5, 7));
}
}
Output
This will produce the following output −
