Using the equals() method with String and Object in Java

Question

Object o1 = new Object();
Object o2 = new Object();
//o1=o2;
System.out.println(o1.equals(o2));

It returns false. It can return true

Answer 1

equals for Object compares memory references.
That is why it is false since they are different Objects
equals for String is overridden to compare based on characters.
You have 2 empty String objects that is why equals returns true.
