Restrictions and Limitations
1. In
Java, generic types are compile time entities. The runtime execution is
possible only if it is used along with raw type.
2.
Primitive type parameters is not allowed for generic programming.
For
example: Stack<int> is not allowed.
3. For
the instances of generic class throw and catch instances are not allowed.
For
example:
public
class Test<T> extends Exception
{
//code

For

new T()
//Error

For
example:
new
Stack<String>[10];//Error
