In this second exercise, we are going to look at the impact of overriding the equals and toString methods. Start by copying over your TestEquals class from the previous exercise. You will not need to make any changes to this code. Instead, you are going to add the following methods to your Ball class:public String toString()public boolean equals(Ball other)public class TestEquals{ public static void main(String[] args) { System. out. println("** Object **"); Object obj1 = new Object(); Object obj2 = new Object(); Object obj3 = obj1; // Copy your entire code from the previous exercise System. out. println("** Ball **"); Ball ball1 = new Ball("Red"); Ball ball2 = new Ball("Red"); Ball ball3 = ball1; }}public class Ball{ private String color; public Ball(String color){ this. color = color; } public String getColor(){ return color; } // Write an equals method here that returns true if // the colors are the same. // Write a toString statement here, for example: // Color: Red }

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
