Help for explaining the output of ubuntu diff command

[zqudm]

I am use diff command in Ubuntu to compare two java file line by line. Suppose the following is the output of two java file. Obviously, the "c" indicate the change action, but i donot know which line does the " return super.equals(obj);" correspond to ? In other words, does " return super.equals(obj);" map to "ShapeList that = (ShapeList) obj;" or to "return true;" ?

<         return super.equals(obj);

>         ShapeList that = (ShapeList) obj;
>         int listSize = size();
>         for (int i = 0; i < listSize; i++) {
>            if (!ShapeUtilities.equal((Shape) get(i), (Shape) that.get(i))) {
>                return false;
>            }
>         }
>         return true;

It's replaced by the whole big > chunk. Left hand side of c is old line number, right hand side is new line number range.
