Design a program that will receive a valid time in the 24-hour format (e.g. 2305) and convert to its equivalent 12-hour format (
coldgirl [10]

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.

melomori [17]

Answer:

The answer is the point - to -point protocol, which allows user to set a secure VPN connection for client and server connectivity.

Explanation:

A virtual private network is a private-public network because of encryption and tunneling to ensure the integrity of the data. VPN requires a tunnel to work and encryption.

In VPNs, there are different protocols can be used, such as point- to - Point Tunneling Protocol (PPTP), IPSec, and L2TP.

Point to Point Protocol is a Microsoft protocol which allows user to set a connection and secure VPN destination. Point to point protocol is designed for client and server connectivity. It developed a connection between two computers. The data link layer that transmits over IP networks is used for point to point tunneling.

Such as option A is not correct because it is distracter and IPSecis primary tunneling protocol. It supports only IP networks. L2TP is not a VPN but extend VPN over the various network.
