Java 8 stream min() and anyMatch() (or sth like that) in one line

Hienz :

I have a list of objects with the following structure:

public class ExampleObject {

    private boolean someBoolean;
    private int someInteger;
    // getters, setters, constructor...
}

I need a method, that will return the integer -1 if any of the objects has the someBoolean field set to true, otherwise return the minimum of someInteger.

I could do it with simple for loop, is there a way to do it with one single stream? My problem was that both anyMatch and min() is terminating the stream.

Eran :

If someInteger is non-negative, you can map each instance to either -1 or someInteger based on the value of the boolean property, and find the minimum:

OptionalInt min = list.mapToInt (o -> o.getSomeBoolean () ? -1 : o.getSomeInteger())
                      .min();

If someInteger can be negative, you can map the instances for which the boolean property it true to Integer.MIN_VALUE, and change the output to -1 if it's equal to Integer.MIN_VALUE.
