Can you explain the difference between "==", ".equals()", and "hashCode()" in Java?
==: Compares object references to check if they refer to the same memory location..equals(): A method from theObjectclass (overridable) used to compare the contents or values of objects. It's used for meaningful comparison.hashCode(): A method from theObjectclass (overridable) that returns a hash code value for an object. It's used for efficient storage and retrieval from hash-based data structures.
