Number Cloning

[Ronin]

I get a "Type mismatch: cannot convert from Object to Number" error when using this code below:

public class ConvolutionMatrixSetting {
   private Number [][] coefficients;
   private Number scale;
   private Number offset;
   private int height;
   private int width;
   private String name;

   public ConvolutionMatrixSetting(String name, Number[][] coefficients,
Number scale, Number offset){
     this.name = name;

     height = coefficients.length;
     width  = coefficients[0].length;

     coefficients = new Number[height][width];
     System.arraycopy(coefficients, 0, this.coefficients, 0, height);

     this.scale = scale.clone(); // DOES NOT WORK
     this.offset = offset.clone(); // DOES NOT WORK
   }

What data-type does scale.clone() produce? You may have to do a data-type conversion.

Not sure, I'll look and post on here.

Isn't the return type of clone() "Object"?

So basically you're trying to assign "Object" to "Number". Maybe you could try:

this.scale = (Number)scale.clone();
this.offset = (Number)offset.clone();
