please solve this using java

Implement the Java method sortByArea, which sorts an ArrayList of rectangles so they are in g order by area. L.e., smaller rectangles will appear on the list before larger ones. You must use the Java sort utility (more info about that on the code handout), and include any additional code necessary to make it work (outside of the sortByArea method). The code handout also has more about the Rectangle class from the Java library. public static void sortByArea (ArrayList boxes)
