Please have a look at the documentation for java.util.Arrays#sort(Object[] a). This utility method sorts the specified array of objects into ascending order, according to the natural ordering of its elements. All elements in the array must implement the Comparable interface.

Can't you use generics to sort, compare "objects"?

You cannot 'sort any object'.
Strictly speaking you may just sort sets having an order criterion defined.
If you need sorting a collection (e.g. an array) of objects then the latter must provide a property (say 'key') such that using it you are be able establish the relative order of any two of them.
Supposing the objects provide such a key then you may use a well-known-good algorithm (like for instance Quick Sort[^] ) for sorting them.
