1) What is the difference between == and equals() in Java?

  • The == operator checks if two references point to the same object in memory.
  • The equals() method checks if two objects are logically equivalent based on their content or values. It can be overridden to provide custom comparison logic.


2) What is a constructor in Java?

A constructor is a special method that is called when an object of a class is created. It has the same name as the class and is used to initialize the object's properties. If no constructor is defined, Java provides a default constructor automatically.
