Need help with inheritance

[hairyjewbear]

Ok so this is the KernelHandler Class

public class KernelHandler extends ImageHandler

I'm getting a cannot find method getWidth()

getWidth is part of the BufferedImage class

I know it has something to do with inheritance, but I need help, please

//Heres the contructor

public KernelHandler(String nameOfFile)
{
super(nameOfFile);


}

// here's the super constructor
public ImageHandler(String nameOfFile){


URL imageURL = getClass().getClassLoader().getResource(nameOfFile);
try
{
myImage = ImageIO.read(imageURL);
}
catch ( IOException e )
{
System.out.println( "image missing" );
}


// Here's the method were trying to use


public static int numOfRedBoxes(String nameOfImg)

{
KernelHandler myHand = new KernelHandler(nameOfImg);
for(int i = 0; i < myHand.getWidth(); i++)

for(int j = 0; j < myHand.getHeight(); j++){
if(img.getRGB(i, j) == red){
numOfRedBoxes++;
}
}
}
return numOfRedBoxes;
}

Post code using CODE tags (see my sig) so it is readable.

Post the full error message text of any errors you are getting.

Post all the relevant code - I don't see any mention of BufferedImage in the code you posted. If KernelHandler extends ImageHandler, what makes you think it should have a getWidth() method?

A prudent question is one-half of wisdom...
