Suppose you have a non-generic method

now this is too general in the sense that it does not express any relationship between k and array this kind of dependency can be achieved using formal type parameter

so now when a generic method is called you can specify the E as you wish like Integer and hence k and array will be of type Integer, for example

this means the call signature is : iAmGeneric(Integer, Integer[])

i hope you got it

I agree. Here's the link: http://aspose.com/file-tools
