实现不同
Comparator的代码（请参见http://docs.oracle.com/javase/6/docs/api/java/util/Comparator.html）
Comparator comparator1 = new Comparator<MyEnum>() { public int compare(MyEnum e1, MyEnum e2) { //your magic happens here if (...) return -1; else if (...) return 1; return 0; }};//and others for different ways of comparing them//Then use one of them:MyEnum[] allChemicals = MyEnum.values();Arrays.sort(allChemicals, comparator1); //this is how you sort them according to the sort critiera in comparator1.
