Override the following methods: compareTo (interface Comparable), toString (class GeometricObject) and equals (class Object).Create an array of comparable circles, sort them and display the result of a sorting procedure. Then create one more circle, which is equal to one of the existing circles and demonstrate the work of the method equals().

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
