Extending the Arrays-class in Java

I'm trying to add functionality to the Arrays-class. In my project I use the (static) methods from Arrays and have some other methods that also handle array-conversion, sorting, etc...

I'm trying to add these to an object MyArrays that extends Arrays so I can go

开发者_运维百科MyArrays.toList(foo);

but also

MyArrays.myOwnFunction(bar);

but i'm not able to extend it because Arrays-contructor has private access. I know it's not really necessary, but now I know i'm unable to do it, I realy want to. Is there any workaround for this?

thanks,

You can't. And why would it matter whether you have the utility functions in one or in two classes? For the record - there is commons-lang's ArrayUtils that has additional utility methods.

Technically, you can reimplement all methods in your utility class by simply calling the corresponding methods in Arrays, but that's unneeded.

I suggest you try using the Trove4j library. This has collections which support primitives has many of the useful Arrays/Collections methods added, like sort(). They can also be extended.
