How to force max to return ALL maximum values in a Java Stream?

Question

I\'ve tested a bit the max function on Java 8 lambdas and streams, and it seems that in case max is executed, even if more than one object compares

Answer 1

System.out.println(
  Stream.of(1, 3, 5, 3, 2, 3, 5)
    .map(a->new Integer[]{a})
    .reduce((a,b)-> 
        a[0]==b[0]?
            Stream.concat(Stream.of(a),Stream.of(b)).toArray() :
            a[0]>b[0]? a:b
    ).get()
)
