Question

Can I create a abstract class like below..?

abstract class A{
private final String    foo;
private final String    too;

public A(final String foo, final String too) {
    this.foo= foo;
    this.too= too;
}
public String getfoo(){
        return foo;
    }
public String gettoo(){
        return too;
    }
}

Answer 1

Yes of course possible.But it is not a good practice because you cant create one object of this class.Main point is that you also dont require this type of class because you have not define any abstract functions inside it. But as per your question you can definitely create this type of abstract class.
