Are there any utils in java which allow to check objects equality without equals overriding? For some reasons I don't want to provide my class with equals method. I need something like SomeUtils.equals(a,b) in my unit test which compares all object fields (via reflection I guess).

1I think you got your answer, do it with reflection.... I don't really see what is the question here. – gaRos May 12 '15 at 15:27

1I don't want to do this by myself. I looking for prepared solution. – Normal May 12 '15 at 15:29

And what if your fields are not primitives? Should these objects also be compared by fields? – Tagir Valeev May 12 '15 at 15:29

In that case the question is off-topic as a recommendation question... – Jon Skeet May 12 '15 at 15:30

1Why don't you want to override [i]equals[/i], it can do no harm to your application in anyway and other methods then can check properly if object a equals object b. Doing it via reflection is a hassle and is everything but efficient – engineercoding May 12 '15 at 15:33

@TagirValeev equals should be used for not primitives fields in my case – Normal May 12 '15 at 15:39

@engineercoding I m not owner of that class and can't access it source code – Normal May 12 '15 at 15:40

So? Apply `equals` recursively if needed. – chrylis -cautiouslyoptimistic- May 12 '15 at 15:40

You could use EqualsBuilder.reflectionEquals(this, obj); in Apache Commons EqualsBuilder

Thanks! That is I'm looking for. As mention by @bhspencer, my question is duplication for http://stackoverflow.com/questions/1449001/is-there-a-java-reflection-utility-to-do-a-deep-comparison-of-two-objects – Normal May 12 '15 at 15:47
