/*
public abstract class PublicAbstractClass{}
public final    class PublicFinalClass{}
       abstract class AbstractClass{}
       final    class FinalClass{}
public          class PublicClass{}
                class Class{}

关于constructor的修饰符组合
abstract  [DEFAULT] protected public

关于field的修饰符组合
4        *    2      *     2      *     2         *    2
权限                      静态的         瞬态的          同步的
private       缺省         缺省          缺省            缺省
缺省       (not final) (not static) (not transient) (not volatile)
protected
public         final       static       transient       volatile

warning:
volatile final 冲突
最终,共有4*2*2*(2*2-1)=48种修饰符组合用于field

关于method的修饰符组合
4         *   2         *    2      *     2      *        2          *   2

protected
public      abstract          final       static        synchronized       native
warning:
abstract 和 private 冲突
abstract 和 final 冲突
abstract 和 synchronized 冲突
abstract 和 static 冲突
abstract 和 native 冲突
所以abstract method 的修饰符组合只有三种:
          abstract
protected abstract
public    abstract
最终,共有4*2*2*2*2+3=67中修饰符组合用于method
