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();
}
}
