java - 枚举类的内部(扩展)版本

Question

这是一个采用 http://www.javatpoint.com/enum-in-java 形式的示例

enum Season{  
    WINTER(10), SUMMER(20); 

    private int value;

    Season(int value) {  
        this.value=value;
    }
}  

作者声称这是编译器为上述枚举类型示例生成的内部代码

final class Season extends Enum {  
    public static Season[] values() {  
        return (Season[])$VALUES.clone();  
    }

    public static Season valueOf(String s) {  
        return (Season)Enum.valueOf(Season, s);  
    }

    private Season(String s, int i, int j) {  
        super(s, i);  
        value = j;  
    }

    public static final Season WINTER;  
    public static final Season SUMMER;  
    private int value;  
    private static final Season $VALUES[];

    static {  
        WINTER = new Season("WINTER", 0, 10);  
        SUMMER = new Season("SUMMER", 1, 20);  
        $VALUES = new Season[] {  
            WINTER, SUMMER  
        };  
    }  
}  

请问哪个工具可以帮助查看枚举的内部(扩展)版本

使用 jad ( http://varaneckas.com/jad/ ) 这是我得到的输出:

final class Season extends Enum
{

    public static Season[] values()
    {
        return (Season[])$VALUES.clone();
    }

    public static Season valueOf(String s)
    {
        return (Season)Enum.valueOf(Season, s);
    }

    private Season(String s, int i, int j)
    {
        super(s, i);
        value = j;
    }

    public static final Season WINTER;
    public static final Season SUMMER;
    private int value;
    private static final Season $VALUES[];

    static 
    {
        WINTER = new Season("WINTER", 0, 10);
        SUMMER = new Season("SUMMER", 1, 20);
        $VALUES = (new Season[] {
            WINTER, SUMMER
        });
    }
}
