The difference between == and === is that: == converts the variable values to the same type before performing comparison . This is called type coercion. === does not do any type conversion (coercion) and returns true only if both values and types are identical for the two variables being compared.

Read moreIs == and Object equals the same?
In simple words, == checks if both objects point to the same memory location whereas . equals() evaluates to the comparison of values in the objects. If a class does not override the equals method, then by default, it uses the equals(Object o) method of the closest parent class that has overridden this method.
Read moreCan we compare 2 objects?
In the first comparison, equals() compares the current object instance with the object that has been passed. If the two objects have the same values, equals() will return true . In the second comparison, equals() checks to see whether the passed object is null, or if it’s typed as a different class.22 Ağu 2019
Read moreCan objects be equal to each other?
Since computing an object’s equality is a time-consuming task, Java also provides a quick way of determining if an object is equal or not, using hashCode() . This returns a small number based on the object’s internal datastructure; if two objects have different hash codes, then they cannot be equal to each other .
Read moreWhat is the use of equals method of Object class?
The equals method for class Object implements the most discriminating possible equivalence relation on objects ; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).
