Question

NOTE: DO NOT USE FLOAT DATA TYPE, OR USE THE EXPRESSION "?" WHILE DOING THE CODE!!

NOTE2: CREATE A CLASS (you can use only import java.util.Scanner;) !!!

Problem 2: (7 marks) public class Time Three instance variables: 1) hour: value of a hours as integer 2) min': value of a minutes as integer 3) sec' value of a seconds as integer A three-argument constructor to initialize all instance variables with values given as parameters if they are valid values using 24 hours format A mutator method that sets the 'sec' field to a value given as a parameter, but only if the given value is valid AtoString method that returns time as 12 hours format An method that increments time by a positive number of seconds given as a parameter only if value is less than or equal 59

Explanation / Answer

Below the the Class Time which has all the specified functions

Time :

public class Time {
  
int hour=-1;
int min=-1;
int sec=-1;
  
Time(int _hour , int _min , int _sec){
if((hour <24) && (min < 60) && (sec <60)){
this.hour = _hour;
this.min = _min;
this.sec = _sec;
}else{
System.out.println("Please Entre Valid Time");
}
  
}
  
public boolean setSeconds(int seconds){
if((hour <24) && (min < 60) && (sec <60)){
if( seconds >=0 && seconds <= 59 ){
sec = seconds;
return true;
}else{
System.out.println("Please entre a value seconds Value");
return false;
}
}
System.out.println("Please Set a Valid Time before setting new Seconds value");
return false;
}
  
public String toString(){
  
if(hour < 0 || min < 0 || sec < 0){
  
return "Valid time Not Set";
}
String meridiem = "AM";
if(hour>=12){
meridiem = "PM";
}
return String.format("%2d:%2d:%2d %s",hour%12,min,sec,meridiem);
}
  
public boolean incrementTime(int seconds){
if(sec < 0 ){
System.out.println("Please Set the time before incrementing");
return false;
}
if( seconds >=0 && seconds <= 59 ){
sec = sec + seconds;
if(sec > 59){
sec = sec%60;
min++;
if(min > 59){
min=0;
hour++;
if(hour > 23){
hour = 0;
}
}
}
return true;
}
System.out.println("Please enter a value between 1 and 59");
return false;
}
  
}

Below The class Main which invokes all the method the Time Class

Main :

import java.util.Scanner;

public class Main {
  
static Time time ;
  
public static void main(String[] args){
  
while(true){
System.out.println("Select any one option");
System.out.println("1. Set new Time");
System.out.println("2. Set Seconds Value");
System.out.println("3. View the Time");
System.out.println("4. Increment the Time with Seconds");
System.out.println("5. Exit");
  
Scanner sc = new Scanner(System.in);
int i = sc.nextInt();
  
switch(i){
  
case 1 :
System.out.println("Enter he Hours Value:");
sc = new Scanner(System.in);
int tempHour = sc.nextInt();
System.out.println("Enter the Minutes Value:");
sc = new Scanner(System.in);
int tempMin = sc.nextInt();
System.out.println("Enter the Seconds Value:");
sc = new Scanner(System.in);
int tempSec = sc.nextInt();
time = new Time(tempHour,tempMin,tempSec);
break;
case 2 :
if(time == null){
System.out.println("Please Set a Valid Time before setting new Seconds value");
continue;
}
  
System.out.println("Enter the Seconds Value to be set");
sc = new Scanner(System.in);
i = sc.nextInt();
  
time.setSeconds(i);
break;
case 3 :
if(time == null){
System.out.println("Please Set a Valid Time ");
continue;
}
System.out.println(time.toString());
break;
case 4 :
if(time == null){
System.out.println("Please Set a Valid Time");
continue;
}
System.out.println("Enter the Seconds Value to be increment");
sc = new Scanner(System.in);
i = sc.nextInt();
time.incrementTime(i);
break;
case 5 :
System.out.println("Thank You ...!");
System.exit(0);
break;
default :
System.out.println("Invalid Input");
break;
  
}
}
}
}
