Compare two objects with .equals() and == operator

Question

I constructed a class with one String field. Then I created two objects and I have to compare them using == operator and .equals() too

Answer 1

The best way to compare 2 objects is by converting them into json strings and compare the strings, its the easiest solution when dealing with complicated nested objects, fields and/or objects that contain arrays.

sample:

import com.google.gson.Gson;


Object a = // ...;
Object b = //...;
String objectString1 = new Gson().toJson(a);
String objectString2 = new Gson().toJson(b); 

if(objectString1.equals(objectString2)){
    //do this
}
