所以,我有一个抽象类,如:

public abstract class AbstractParent <E extends Enum<E>> {...}

在AbstractParent里面的非抽象方法的某处,我想迭代E的值.这可能吗？

更好的例子:

public abstract class AbstractParent <E extends Enum<E>> {
    ...
    protected void doSomething() {
        //iterate over the values of E and perform an action using them
    }
}

public class Child extends AbstractParent<Child.Index> {
    public static enum Index {
        ...
    }
    public Child() {
        super();
        this.doSomething(); //this should iterate over Index's values
    }
}

所以,感谢mdma,这非常有效:

public abstract class AbstractParent <E extends Enum<E>> {
    ...
    protected void doSomething() {
        //iterate …
