Multiple Inheritance is not supported in Java

Below diagram explains is called Diamond Problem because of the inheritance structure.
      A foo()
          / \
         /   \
foo() B C foo()
         \   /
          \ /
        D foo()

 Multiple inheritance does cause casting, constructor chaining,etc problems.
Also, multiple inheritance leads to complexity.
Hence, Java do not support multiple inheritance.
But recently, in JAVA 8, this problem is handled in different way, that is, the compiler will throw exception in this scenario and we will have to provide implementation logic in the class implementing the interfaces.

@Overrride annotation introduced in Java1.5

Whenever we have a subclass that implements parent method it is marked with annotation as @Override. This is to make compiler know that the child overrides the method defined or declared in parent. If @Overrride annotation is commented, the subclass will work as it was. But if in future, the signature of parent class changes, the compiler wont ask to implement the method instead it will think subclass has overloaded the method present in base class. If you uncomment @Override annotation, the compiler will throw compile time error as method signature in parent class has changed. Annotation should be used as standard as- It ensures that for any change in method signature of parent class, compiler will ask to change it for the subclasses.    Also it is better to resolve issue in compile time rather than runtime

Liskov Substitution Principle (LSP)

Subtypes must be substitutable for their base types. This principle supports the below scenario-    Suppose a method takes parent type and perform some operation on it.    And the subtype is not of type - parent but still wrongly inherits the parent.        If the above subtype object is passed to such method, the operation performed will be weird as the method assumes it is suppose to be parent type. Hence, a class should inherit parent only if its of that type. (eg: Square is not Rectangle programmatically as the area is always side^2)

Lets start with some choc delicacy...  All you need to have -  1 Packet of Marie biscuits 4 cups of Milk 4-5 tbsp. Sugar (Grinned it to powder) 3 tbsp. Custard Powder 4 tbsp.

Mix them well. Be sure to make fine thick liquid. If required, you can use a blender to mix them well. 3. In a vessel, heat 2 cups of milk. 4. When it comes to boil, add the prepared milk mixture. 5. Stir slowly and continuously, else you will end up making a chocolate liquid having lumps.... a big NO NO!!! 6. Once you see thick liquid, remove it from flame. 7. Place biscuits on plate. 8. With a spoon, pour choco liquid on biscuits 9. Top it with one more layer of biscuit. 10. Repeat 8 and 9 step, till u get 4 layers of biscuits (OR whatever height you wish). 11.
