Answer 1

Hi, please find the program below:

public class Time {

private int hour;
private int minute;
private int second;
  
  
public Time(int hour, int minute, int second) {
this.hour = hour;
this.minute = minute;
this.second = second;
}

public int getHour() {
return hour;
}

public void setHour(int hour) {
this.hour = hour;
}

public int getMinute() {
return minute;
}

public void setMinute(int minute) {
this.minute = minute;
}

public int getSecond() {
return second;
}

public void setSecond(int second) {
this.second = second;
}
  
public void setTime(int hour, int minute, int second) {
this.hour = hour;
this.minute = minute;
this.second = second;
}
  
public String toString() {
return String.format("%02d", hour) +":" + String.format("%02d", minute) + ":" + String.format("%02d", second);
}

public Time nextSecond() {
if(minute == 59 && second==59) {
minute=0;
second=0;
if(hour==23)
hour=0;
else
hour++;
}
else if(second == 59) {
second=0;
minute++;
}
else {
second++;
}
  
return this;
}
  
public Time previousSecond() {
if(minute == 0 && second==0) {
minute=59;
second=59;
if(hour==0)
hour=23;
else
hour--;
  
}
else if(second == 0) {
second=59;
minute--;
}
else {
second--;
}
  
return this;
}

public static void main(String[] args) {
Time t1=new Time(5,10,59);
System.out.println("Time- "+t1.toString() +" Next Second: "+ t1.nextSecond() );
Time t2=new Time(5,10,0);
System.out.println(" Time- "+t2.toString() + " Previous second: "+ t2.previousSecond());
Time t3=new Time(22,0,0);
System.out.println(" Time- "+t3.toString() + " Previous second: "+ t3.previousSecond());
Time t4=new Time(0,0,0);
System.out.println(" Time- "+t4.toString() + " Previous second: "+ t4.previousSecond());
Time t5=new Time(2,59,59);
System.out.println(" Time- "+t4.toString() +" Next Second: "+ t4.nextSecond());
}
}

Output:

Time 05:10:00 Previous second: 05:09:59 Time- 22:00:00 Previous second: 21: 59:59 Time- 00:00:00 Previous second: 23: 59:59 Time-23:59:59
