Yes, we can create an object of that class, but, we cannot
extend it.

Answer / sp

Object can be created only within the same class but not in
another class (including sub class)

Eg:
// valid instantiation
public class ClassWithPrivateConstructors {

private ClassWithPrivateConstructors() {
System.out.println("object created");
}
public static void main(String args[]) {
ClassWithPrivateConstructors t = new
ClassWithPrivateConstructors();
}
}

//invalid instantiation - subclass
public class SubClassWithPrivateConstructors extends
ClassWithPrivateConstructors {
public NewClassConstructorTest(String name) {
//implicitly super() constructor in super
class is invoked.
System.out.println("New sub class object created" + name);
}
}

//invalid instantiation - reference class
public class ClassWithPrivateConstructorsTest {

public ClassWithPrivateConstructorsTest() {
ClassWithPrivateConstructors c = new
ClassWithPrivateConstructors();
}
}

Paul the octopus who has been forecasting the outcome of FIFA world cup matches with tremendous accuracy has now been invited to predict ICC world cup matches in 2011. We will assume that the world cup contenders have been divided into 2 groups of 9 teams each. Each team in a group plays the other teams in the group. The top two teams from each group enter the semi finals ( after which the winner is decided by knockout). However, Paul has a soft spot for India and when India plays any team, Paul always backs India. Alas, his predictions on matches involving India are right only 2 out of 3 times. In order to qualify for the semi finals, it is sufficient for India to win 7 of its group matches. What is the probability that India will win the ICC world cup?
