The original code may be slightly incorrect (my understanding
of java generics is not high).
Test1.java is defined as:
public class Test1<T extends Base> {
public class Inner1 {
protected T v;
public Inner1(T v) {this.v = v;}
public T getV() {return this.v;}
}
public Inner1 getInner(T v) {return new Inner1(v);}
}
It could also be defined as:
package test;
public class Test1<T extends Base> {
public class Inner1<T extends Base> {
protected T v;
public Inner1(T v) {this.v = v;}
public T getV() {return this.v;}
}
public Inner1 getInner(T v) {return new Inner1<T>(v);}
}
The second definition makes the Inner1 class explictlly be a generic class,
Test2 then is:
package test;
public class Test2<T extends Base> extends Test1<T> {
public class Inner2 extends Inner1<T> {
public Inner2(T v) {super(v);}
}
}
and Test3 is unchanged.
In this case, compilation works fine.
