Write a version that only decreases the red by 10%, and one that reduces red by 20%. Which seems to be more useful? Note that you can always repeatedly reduce the redness in a picture, but you don't want to have to do it too many times, either.

Question

What will be an ideal response?

Answer 1

```
public void decreaseRed10P ( )
{
Pixel [ ] pixelArray = this.getPixels ( ) ;
int red = 0 ;
// loop through all the pixels
for ( Pixel currPixel : pixelArray )
{
red = c urrPixel . getRed ( ) ;
currPixel . setRed ( ( int ) ( red ¤ 0 . 9 ) ) ;
}
}
public void decreaseRed20P ( )
{
{Pixel [ ] pixelArray = this.getPixels ( ) ;
int red = 0 ;
// loop through a ll the pixels
for ( Pixel currPixel : pixelArray )
{
red = currPixel.getRed ( ) ;
currPixel.setRed ( ( int ) ( red *0 . 8 ) ) ;
}
}
```
