Java Programming

Hi ,

I have code, But this working for we need give input as file object. But i need as byte[] object. Code is

byte[] output=null;
double new_width=300;
Image image=new ImageIcon(input).getImage();
double w=image.getWidth(null);
double h=image.getHeight(null);
if(w < new_width){
return output;
}
if(new_width==-1 && w< 1000){
return output;
}else if(new_width ==-1 && w > 1000){
new_width=1000;
}
double nw=new_width;
if(new_width==-1){
nw=w;
}
double scalex_width=nw/w;
double scalex_height=scalex_width;
BufferedImage bi=new BufferedImage(image.getWidth(null),image.getHeight(null),BufferedImage.TYPE_INT_RGB);

Graphics2D imageGraphics=bi.createGraphics();

imageGraphics.drawImage(image,0,0,null);
BufferedImageOp op=new AffineTransformOp(AffineTransform.getScaleInstance(scalex_width,scalex_height),null);

bi=op.filter(bi,null);
Raster raster = bi.getData();
DataBufferByte ddb = (DataBufferByte)raster.getDataBuffer();
output = ddb.getData();
return output;


But if ia send byte[] input to this code means it is gettfing these Exception
