应用
enum Type{
BOOK,NOTEBOOK
}
实现原理
编译器会生成一个继承enum接口的Type类，对编译的Type.class使用jad反编译可以得到
final class Type extends Enum
{
private Type(String s, int i)
{
super(s, i);
}
public static Type[] values()
{
Type atype[];
int i;
Type atype1[];
System.arraycopy(atype = ENUM$VALUES, 0, atype1 = new Type[i = atype.length], 0, i);
return atype1;
}
public static Type valueOf(String s)
{
return (Type)Enum.valueOf(liupeng/cn/Algorithm/thread/Type, s);
}
public static final Type BOOK;
public static final Type NOTEBOOK;
private static final Type ENUM$VALUES[];
static
{
BOOK = new Type("BOOK", 0);
NOTEBOOK = new Type("NOTEBOOK", 1);
ENUM$VALUES = (new Type[] {
BOOK, NOTEBOOK
});
}
}
