Java variables act as object or not?
How a Java variable would act depends on the variable's data type. Variables of the primitive data types like int, char, float etc would not act as objects. But apart from them, all other data types would act as Objects. Almost all data types would extend from java.lang.Object and would behave as objects.
What is deserialization in java?

Why java not use int as a generic argument?
Only Objects can be used as generic arguments. Primitives Data Types (int, long, char ...) are not objects. But you can use Integer, an Object that wrap the data type int instead.
Do the primitive datatypes in java have objects?
No Primitive data types do not have objects. As of Java 1.5, all primitive types in Java have "wrapper" classes. These classes serve two purposes: # They keep all type-specific methods together in one place. # They allow primitive types to be used in situations which take advantage of generics (also introduced in Java 1.5).
