I'm getting an error that says Error: The method
compare(int, int) is undefined for the type Integer for the bolded
parts of the code
public boolean compare(Rectangle R) {
//Compare the values of objects and return value
accordingly
return Integer.compare(x, R.x) == 0
&& Integer.compare(y, R.y) == 0
&& Integer.compare(width, R.width) == 0
&& Integer.compare(height, R.height) == 0;
