Object Class in Java

The Object class is the root class of all Java classes. Every class in Java directly or indirectly inherits from it.

Key Methods:

1. toString():
   • Returns a string representation of the object.
   java

   Copy code

   @Override
public String toString() {
return "Class Details";
}

2. equals(Object obj):
   • Compares two objects for equality.
   java

   Copy code

   obj1.equals(obj2);

3. hashCode():
   • Returns the hash code of the object.
   java

   Copy code

   int hash = obj.hashCode();

4. getClass():
   • Returns the runtime class of the object.
   java

   Copy code

   Class cls = obj.getClass();

5. clone():
   • Creates a copy of the object (requires Cloneable interface).
6. finalize():
   • Called before garbage collection.

Example:

The Object class ensures consistency and interoperability in Java’s class hierarchy.
