== should only be used to compare primitive types (i.e. int, char, float etc). The reason being if it is used on Objects like Strings or your defined classes, Java will only return True if the two Objects are identical. This includes where they are stored in memory. So it will only return true if you are comparing an Object to itself. 

//example Strings
String noun = "Code Monkey";
String anotherNoun = "Code Monkey";

//this returns true
noun == noun;

//these return false
noun == anotherNoun;
noun == "Code Monkey";

*Side note the single = is the assignment operator and does not do comparison
