sorting an array that contains Methods by modifiers

DISCLAIMER: This is only part of a homework assignment I am currently doing

Say I have a method array which contains all of my declared methods

Method methodList[] = classGetter.getDeclaredMethods();

in which classGetter simply gets what class I want to get the methods of. Is there a way to sort this array by what kind of modifier is associated with the method? I see that when I print out the modifier using

for(Method m: methodList){
    System.out.println(m.getModifiers());
}

it returns integer values. I tried to sort using the Arrays.sort method but I got error exceptions. Any Pointers?
