Explanation / Answer

Dear,

class Time {
//fields
private int currentHour;
private int currentMinute;
private boolean amOrPm;

/*
* A constructor with three parameters
*/
public Time(int currentHour, int currentMinute,boolean amOrPm)
{
if (currentHour < 1 || currentHour > 12)
throw new IllegalArgumentException("invald hour: " + currentHour);

if (currentMinute < 0 || currentMinute > 59)
throw new IllegalArgumentException("invalid Minute: " + currentMinute);

this.currentHour = currentHour;
this.currentMinute = currentMinute;
this.amOrPm=amOrPm;

}


/*
* getHour-returns the hour component of a Time object.
*/
public int getHour() {
return this.currentHour;
}
/*
* getMinute- returns the minute component of a Time object.
*/
public int getMinute() {
return this.currentMinute;
}
/*
* isAm- returns true if the Time is AM, and false otherwise.
*/
public boolean isAM()
{
if(currentHour< 12){
return (this.amOrPm);
}
else{
return false;
}
}

/*
* advanceHour- advances the Time by 1 hour.
*/
public void advanceHour() {
this.currentHour +=1;
if (currentHour > 12) {
this.currentHour = 1;
this.isAM();
}
}
/*
* advanceMinute- advances the Time by 1 minute.
*/
public void advanceMinute() {
this.currentMinute += 1;
if(currentMinute > 59) {
this.currentMinute=0;
advanceHour();
this.isAM();
}
}
/*
* advanceMinute- takes a parameter specifying a number
* of minutes and advances Time by that number of minutes
*/
public void advanceMinute(int tMinute) {
this.currentMinute += tMinute;
if(currentMinute > 59) {
this.currentMinute= (tMinute-60);
advanceHour();
this.isAM();
if(currentMinute < 0) {
this.currentMinute = 0;
this.isAM();
}
}
}
/*
* equals- returns true if the calling object has the same
* components (hour, minute, and AM/PM) as the obeject
* represented by the parameter, and false otherwise.
*/
public boolean equals(Time other) {
return (other != null
&& this.currentHour == other.currentHour
&& this.currentMinute == other.currentMinute
&& this.amOrPm == other.amOrPm);
}
/*
* toString- returns a String of the form HH:MM,
* followed by whether AM or PM.
*/
public String toString() {
String str= "";
if(currentHour < 12 )
str=this.currentHour + "" + ":" + this.currentMinute +" AM";
if(currentHour >12)
str=this.currentHour + ":" + this.currentMinute + " PM";
return str;
}

}
public class TimeDriver {

public static void main(String[] args)
{
Time time1=new Time(5,59,true);
Time time2=new Time(5,59,true);
System.out.println(time1);
System.out.println(time2);
if(time1.isAM())
System.out.print("AM");
else
System.out.print("PM");

if(time1.equals(time2))
System.out.println("Equal");
else
System.out.println("Not -Equal");

}

}

Hope this would helpful to you...
