Loop through HashSet of Objects Java

Question

I am trying to loop through a HashSet of Enum Objects in Java 8 to see if a value is equal to a specific string. I have tried both equals and == but its not returning true.

HashSet looks like:

I have tried the following:

for(Object g : groups){
                if(g.equals("group_certification_staff")){
                    //Do stuff
                }


for(Object g : groups){
                if(g == "group_certification_staff"){
                    //Do stuff
                }

but it keeps returning false

What am I missing?

If `groups` contains `Enum` objects, then don't compare them to `String`s. Compare them to the `Enum` that you're looking for. Change `g == "group_certification_staff"` to `g == SecurityGroup.group_certification_staff` — mypetlion, Oct 31 '19 at 18:53
Out of curiosity, is there a reason for using a String instead of `g.contains(SecurityGroup.group_certification_staff)`? — VGR, Oct 31 '19 at 19:18
@VGR - no. I'm not use to working in Java - its honestly just lack of experience/knowledge with this. The statement given previous by mypetition was correct — reactFullStackDeveloper, Oct 31 '19 at 19:59

Strings do not equal enums. You could write something like g.name().equals("group_certification_staff") to see if it has the same name.
