In Java, your class extends Comparable, then provides a definition of comparesTo(). You can now use your class with anything that wants to sort or search. You could argue the difference is just semantics or syntactic sugar. Still, the concept and syntax of function pointers is considerably more difficult to understand, and results in code that isn't as checkable by the compiler and can cause really wacky things to happen if you mess it up. In C, if I accidentally pass my string compare function to qsort while I'm trying to sort an array of ints, the program will compile and run, and then screw up badly at runtime.
