Question

i see some examples in java where vectors are declared as

Vector v = new Vector() 

and in some examples,

Vector<String> = new Vector<String>()

i am not sure what does the latter declaration do? does it specify the type of Objects the Vector shud consist of?

if yes, then if i declare a Vector using the first declaration i can use any type of Objects and if i use the second declaration, then the object can only be of type within <>?

Answer 1

The first line defines a Vector of Objects that can be of any type.

The second line uses Java Generics und define a Vector that only holds Strings.
