Below is the code for a Time class that has both an equals method and a hashCode method; however, the body of the hashCode method is missing. In the text box, write the code you would put inside the body of the hashCode method. Remember that a hashCode with no collisions is better than a hashCode that has collisions and a hashCode with no gaps in the values is better than a hashCode that has gaps. public class Time { private int hour; // A number between 1 and 12 private int min; // A number between 0 and 59 private boolean pm; // True if the time is pm. public Time(int hour, int min, boolean pm) { this.hour = hour; this .min = min; this.pm = pm; } public int getHour() { return hour; } public int getMin() { return min; } public boolean isPM() { return pm == true; } public boolean isAM() { return pm == false; } public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; Time other = (Time) obj; if (hour != other.hour) return false; if (min != other.min) return false; if (pm != other.pm) return false; return true; } public int hashCode() { // INSERT CODE HERE } }

Below is the code for a Time class that has both an equals method and a hashCode method; however, the body of the hashCode method is missing. In the text box, write the code you would put inside the body of the hashCode method. Remember that a hashCode with no collisions is better than a hashCode that has collisions and a hashCode with no gaps in the values is better than a hashCode that has gaps.

public class Time {

private int hour; // A number between 1 and 12

private int min; // A number between 0 and 59

private boolean pm; // True if the time is pm.

public Time(int hour, int min, boolean pm) {

this.hour = hour;

this .min = min;

this.pm = pm;

}

public int getHour() { return hour; }

public int getMin() { return min; }

public boolean isPM() { return pm == true; }

public boolean isAM() { return pm == false; }

public boolean equals(Object obj) {

if (this == obj)

return true;

if (obj == null)

return false;

if (getClass() != obj.getClass())

return false;

Time other = (Time) obj;

if (hour != other.hour)

return false;

if (min != other.min)

return false;

if (pm != other.pm)

return false;

return true;

}

public int hashCode() {

// INSERT CODE HERE

}
