Java - String.join() does not equal its string

Question

I have list = [1,0,1], but each number in the List are of type String. I do

if ( String.join("",list) == "101"){ 
    return true
}

As you can see, these to Strings are equal but it won't return true.

`==` is fit your requirement, please use `str1.equals(str2)` — Ninja, Jun 15 '16 at 13:40
ok the answer is to use `.equals`. I am assuming you didnt know the difference between using `==` and `.eqauls`. I recommend reading http://stackoverflow.com/questions/767372/java-string-equals-versus — Mukul Goel, Jun 16 '16 at 11:56
