1.why does a Object type (not the reference variable's type), determines which overridden
method is used at runtime ?

2.why does a Reference type determines which overloaded method will be used at
compile time ?

Reference variables are checked at compile time hence the overloaded method invocations are checked at compile time
and remember that objects those are created using "new" keyword are created at run time hence the methods to be called on those objects are called at run time

I agree with prasad , If run time polymorphism would not be there, we might lost the beauty of java polymorphism...
