Use Of Generics In Dot Net Frame

The purpose of Generics is introduce the Compiler with the type of Collection., so that the compiler can verify at Compile Time that Type Constraints are not violated at runtime.

Advantages Of Using Generics

1. Using generics in your applications makes it Clearer and Safer.
2. It eliminates unsafe Cast and extra parantheses.

Take the example to make it more clear

I am showing the same functionality with and without generics.
In this problem we have to remove all the elements of length from the collection of elements

(1.)Without Generics.

Static void nongenerics( collection c)
{
for (Iterator i = c.iterator(); i.hasNext(); )
if (((String) i.next()).length() == 4)
i.remove();
}

(2.)Let us apply generics to the same above code

Static void genenerics( Collection c)
{
for (iterator i=c.iterator( );i.hasnext( );)
if(i.next( ).length==4)
i.remove();
}

The Collection in code 2. above is read as Collection Of Type c. Now, (Using Generics) the compiler can verify at compile time that constraints are not violated at runtime. Also, the variable c holds true whenever and wherever it is used and the compiler guarantees it. Cast on the other hand shows what the programmer thinks is true at the single point in the code.
