Is the following program written correctly? If yes then what will be the output of the program?

abstract class Calculate  
{  
    abstract int multiply(int a, int b);  
}  
   
public class Main  
{  
    public static void main(String[] args)  
    {  
        int result = new Calculate()  
        {    
            @Override  
            int multiply(int a, int b)  
            {  
                return a*b;  
            }  
        }.multiply(12,32);  
        System.out.println("result = "+result);  
    }  
}  

Yes, the program is written correctly. The Main class provides the definition of abstract method multiply declared in abstract class Calculation. The output of the program will be:
