No, you cannot.

class A
{
private A() { 
    System.out.println("Hello");
}
}

class B extends A
{
public static void main(String[]args){
    A a=new A();
}
}

class A
{
private A() { 
    System.out.println("Hello");
}
public static A B(){
A obj= new A();
return obj;
}
}

class B extends A
{
public static void main(String[]args){
    A.B();
}
}
