The code is

public class Multiply
{
   public static Double multiply(Double a, Double b)
   {
       return a * b
   }
}

I cannot solve the above code. I tried a few things, like

public class Multiply 
{ 
   public double multiply(double a, double b) 
   { return a * b;} 
}

It still shows errors in code. Kindly help, please.

You essentially had the answer Codewars wanted. I imagine they expected for you to just add the semicolon, as you did, but keep the rest of the code the same.

public class Multiply
{
   public static Double multiply(Double a, Double b)
   {
       return a * b;
   }
}

I went to try it out, and this worked for me. Looks like they wanted you to keep static and the wrapper class Double.
