Incompatible types when returning value

Question

I want to display an image with drawn lines on a map, and separate images made for every single section in the image (several connected lines). I have written this code:

Answer 1

some people may find confusing when they don't know that

BufferedImage lineImage1[] = null;

is the same as

BufferedImage[] lineImage1 = null;

and you cannot have two returns, it's illegal in Java.

So if you want to return more than one object, you can do something like

public Object[] getLineImage() {
(...)
    Object[] o = new Object[2];
    o[0]=lineImage;
    o[1]=lineImage1;
    return o;
}
