Consider the class definitions and answer the questions: Complete the missing parts of the code…

Complete the missing parts of the code given below:

class SI ?1? Account     
{                            
    double sINT; 
    public SI (double sP, double sR, double sT) 
    { 
        ?2?                                           
        sINT = 0; 
    } 
    public void Interest() 
    {   
        sINT = (P * R * T) / 100;  
    } 
    public void display() 
    { 
        ?3? //invoke display( ) of base class                
        Interest(); 
        System.out.println("Simple Interest=" + sINT);      
    } 
} // class ends

Answer the following questions, based on the above code: (i) Name the base class and derived class (ii) Write the prototype of the base class constructor.
