Answer:
import java.io.*;
public class Main
{
public static void main(String[] args) throws IOException {
BufferedReader bufferObject=new BufferedReader(new InputStreamReader(System.in));
String stringObject=bufferObject.readLine();
while(!stringObject.equals("99:99AM")){
System.out.println(convertedTime(stringObject));
stringObject=bufferObject.readLine();
}
}
public static String convertedTime(String stringObject){
String s=stringObject.substring(stringObject.length()-2);
String[] timeObject=stringObject.substring(0,5).split(":");
if(s.equals("AM")){
if(timeObject[0].equals("12")) return "00"+timeObject[1];
else return timeObject[0]+timeObject[1];
}
else{
if(timeObject[0].equals("12")) return "12"+timeObject[1];
else{
int hours=Integer.valueOf(timeObject[0]);
timeObject[0]=String.valueOf(12+hours);
return timeObject[0]+timeObject[1];
}
}
}
}
Explanation:
- Inside the main method run a while loop until stringObject is not equal to the string "99:99AM".
- Call the convertedTime method and display the results.
- Use the same hours and minutes except for 12th hour If the time is in AM.
- Use "00" instead of 12, if it is 12th hour.
- Add hours to 12, if the time is in PM and don't change anything in case of 12.
