top class的修饰符组合
abstract final public
2 * 2 * 2
warning:
abstract final 冲突
最终,共有2*(2*2-1)=6种修饰符组合用于top class
*/
/*
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
权限 静态的 同步的 本地的
private 缺省 缺省 缺省 缺省 缺省
缺省 (not abstract) (not final) (not static) (not synchronized) (not native)
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
