Q) What is the output of the program?




class A{
       A(int a)
       {
       System.out.println("object created");
    }
}

class  constructortest {  
public static void main(String[] args) {
              A a1 = new A();
       }

}

A)

Output:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
       A cannot be resolved to a type
       A cannot be resolved to a type

       at constructortest.main(constructortest.java:8)

->in the above program causes “compilation error”.

->reason is, in the object creation syntax zero argument constructor is used, but zero argument constructor not available in the class.
