What is the difference between ‘ == ’ and ‘equals()?

“==” or equality operator in Java is a binary operator provided by Java programming language and used to compare primitives and objects. public boolean equals(Object o) is the method provided by the Object class. The default implementation uses == operator to compare two objects. For example: method can be overridden like String class. equals() method is used to compare the values of two objects.

Equals() method is defined in Object class in Java and used for checking equality of two objects defined by business logic.
