java-类、接口、方法、字段等都有哪些修饰符了？

1、java中修饰符在哪里规定了？

所有修饰符所在类[Modifier]为如下：

package java.lang.reflect;

import java.security.AccessController;
import sun.reflect.LangReflectAccess;
import sun.reflect.ReflectionFactory;

/**
 * The Modifier class provides {@code static} methods and
 * constants to decode class and member access modifiers.  The sets of
 * modifiers are represented as integers with distinct bit positions
 * representing different modifiers.  The values for the constants
 * representing the modifiers are taken from the tables in sections 4.1, 4.4, 4.5, and 4.7 of
 * The Java™ Virtual Machine Specification.
 *
 * @see Class#getModifiers()
 * @see Member#getModifiers()
 *
 * @author Nakul Saraiya
 * @author Kenneth Russell
 */
public class Modifier {

//...

}

2、修饰符分类

2.1、所有修饰符定义

/*
     * Access modifier flag constants from tables 4.1, 4.4, 4.5, and 4.7 of
     * The Java™ Virtual Machine Specification
     */

    public static final int PUBLIC           = 0x00000001;

    public static final int PRIVATE          = 0x00000002;

    public static final int PROTECTED        = 0x00000004;

    public static final int STATIC           = 0x00000008;

    public static final int FINAL            = 0x00000010;

    public static final int SYNCHRONIZED     = 0x00000020;

    public static final int VOLATILE         = 0x00000040;

    public static final int TRANSIENT        = 0x00000080;

    public static final int ABSTRACT         = 0x00000400;

    public static final int STRICT           = 0x00000800;

    // Bits not (yet) exposed in the public API either because they
    // have different meanings for fields and methods and there is no
    // way to distinguish between the two in this class, or because
    // they are not Java programming language keywords

    static final int BRIDGE    = 0x00000040;
    static final int VARARGS   = 0x00000080;
    static final int SYNTHETIC = 0x00001000;
    static final int ANNOTATION  = 0x00002000;
    static final int ENUM      = 0x00004000;
    static final int MANDATED  = 0x00008000;
    static boolean isSynthetic(int mod) {
      return (mod & SYNTHETIC) != 0;
    }

2.2、类修饰符

 /**
     * The Java source modifiers that can be applied to a class.
     * @jls 8.1.1 Class Modifiers
     */
    private static final int CLASS_MODIFIERS =
        Modifier.PUBLIC         | Modifier.PROTECTED    | Modifier.PRIVATE |
        Modifier.ABSTRACT       | Modifier.STATIC       | Modifier.FINAL   |
        Modifier.STRICT;

2.3、接口修饰符

    /**
     * The Java source modifiers that can be applied to an interface.
     * @jls 9.1.1 Interface Modifiers
     */
    private static final int INTERFACE_MODIFIERS =
        Modifier.PUBLIC         | Modifier.PROTECTED    | Modifier.PRIVATE |
        Modifier.ABSTRACT       | Modifier.STATIC       | Modifier.STRICT;

2.4、构造器修饰符

 /**
     * The Java source modifiers that can be applied to a constructor.
     * @jls 8.8.3 Constructor Modifiers
     */
    private static final int CONSTRUCTOR_MODIFIERS =
        Modifier.PUBLIC         | Modifier.PROTECTED    | Modifier.PRIVATE;

2.5、方法修饰符

    /**
     * The Java source modifiers that can be applied to a method.
     * @jls8.4.3  Method Modifiers
     */
    private static final int METHOD_MODIFIERS =
        Modifier.PUBLIC         | Modifier.PROTECTED    | Modifier.PRIVATE |
        Modifier.ABSTRACT       | Modifier.STATIC       | Modifier.FINAL   |
        Modifier.SYNCHRONIZED   | Modifier.NATIVE       | Modifier.STRICT;

2.6、字段修饰符

    /**
     * The Java source modifiers that can be applied to a field.
     * @jls 8.3.1  Field Modifiers
     */
    private static final int FIELD_MODIFIERS =
        Modifier.PUBLIC         | Modifier.PROTECTED    | Modifier.PRIVATE |
        Modifier.STATIC         | Modifier.FINAL        | Modifier.TRANSIENT |
        Modifier.VOLATILE;

2.7、参数修饰符

    /**
     * The Java source modifiers that can be applied to a method or constructor parameter.
     * @jls 8.4.1 Formal Parameters
