You can use the following code:

static <E> E yourMethod(){
    AbsEntity absEntity = new AbsEntity();
    return (E)absEntity;
}

It should be declared before the return type, like so:

    abstract <E extends AbsEntity> Class<E> getAbsEntity();

Take a Look here at Oracle docs.

Hope this helps!

Something like this:

public <E extends AbsEntity> E yourMethod() {
    //yourObject
    return yourObject;
}
