The code for the DoubleStream.count method is incorrect:
public final long count() {
return mapToObj(e -> null).mapToInt(e -> 1).sum();
}
If a a double stream contains more than Integer.MAX_VALUE then the sum will overflow resulting in an incorrect value. The code should be:
public final long count() {
return mapToLong(e -> 1).sum();
}
public final long count() {
return mapToObj(e -> null).mapToInt(e -> 1).sum();
}
If a a double stream contains more than Integer.MAX_VALUE then the sum will overflow resulting in an incorrect value. The code should be:
public final long count() {
return mapToLong(e -> 1).sum();
}
