Object Oriented Programming: Unit IV: I/O, Generics, String Handling
Restrictions and Limitations
Generics | Java OOPs
In Java, generic types are compile time entities. The runtime execution is possible only if it is used along with raw type.Primitive type parameters is not allowed for generic programming.
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
// Error:can't extend the Exception class
}
4.
Instantiation of generic parameter T is not allowed.
For
example:
new T()
//Error
new
T[10]
5.
Arrays of parameterized types are not allowed.
For
example:
new
Stack<String>[10];//Error
6.
Static fields and static methods with type parameters are not allowed.
