generics

[Abhishek Bhat]

This generics has endless secrets...

   
 class A<String>
{
public static void main(String args[])
{}
}

 

Why does it give this error :

non-static class String cannot be referenced from a static context
public static void main(String args[])

[Punit Singh]

No you are using something like this:

 class A<T>  
{  
public static void main(T args[])  
{}  
}    

Got any idea? Or I need to say some more.

Would the error make more sense, if it was written like this?

class A<T>   
{   
    public static void main(T args[])   
    {}   
}   

You have confused the compiler. Your first "String" is actually a type. And your second "String" is the java.lang.String class.

Hi Punit,

My attempt to do that was in the line of the <T> concept only...i was testing using all the different Types....the error however was not expected
The rule is ok but the Type conflict is bizzare with the "main" method argument...

Thanks anyway Punit and Henry ... Thanks a lot
