Tugas 2 - Biodata dan Waktu

1. Program untuk mencetak Biodata

public class Biodata

{

    public Biodata(){

        System.out.println("==============Biodata==============");

        System.out.println("\n");

        System.out.println("Nama    : Abdi Dewa Maha Rupawan");

        System.out.println("NRP     : 05111840000003");

        System.out.println("Kelas   : PBO - D");

        System.out.println("TTL     : 30 Juli 2001");

       

    }

}

 2. Program untuk menunjukkan waktu dg format 24 jam atau 12 jam AM/PM

Program Untuk Waktu

public class Time

{

    private int hour,minute,second;

   

    public Time(){

        hour = 12;

        minute = 30;

        second = 0;

    }

    public Time(int hour, int minute, int second){

        if( ( hour>=0 && hour<24 ) && ( minute>=0 && minute<60 ) && ( second>=0 && second<60 ) ){

            this.hour = hour;

            this.minute = minute;

            this.second = second;

        }

        else{

            throw new IllegalArgumentException(

                "Format jam, menit, dan/atau detik tidak valid (jam 0-23, menit 0-59, detik 0-59)"

            );

        }

    }

   

    public void setTime(int hour, int minute, int second){

        if( ( hour>=0 && hour<24 ) && ( minute>=0 && minute<60 ) && ( second>=0 && second<60 ) ){

            this.hour = hour;

            this.minute = minute;

            this.second = second;

        }

        else{

            throw new IllegalArgumentException(

                "Format jam, menit, dan/atau detik tidak valid (jam 0-23, menit 0-59, detik 0-59)"

            );

        }

    }

   

    public String Format24h(){

        return String.format("%02d:%02d:%02d\n",hour,minute,second);

    }

   

    public String Format12h(){

        String mode;

        int fhour;

       

        if(hour>=12){

            mode = "PM";

        }

        else{

            mode = "AM";

        }

       

        if(hour!=12){

            fhour = hour%12;

        }

        else{

            fhour = hour;

        }

        return String.format("%02d:%02d:%02d %s\n",fhour,minute,second,mode);

    }

}

Program Untuk Eksekusi

public class Timetest

{

    public static void main(String[] args){

        Time time = new Time();

       

        System.out.println("Waktu Mula2 (Format 24 jam)");

        System.out.println( time.Format24h() );

        System.out.println("Waktu Mula2 (Format AM/PM)");

        System.out.println( time.Format12h() );

        System.out.println();

       

        time.setTime(12, 37, 38);

       

        System.out.println("Waktu Sekarang (Format 24 jam)");

        System.out.println( time.Format24h() );

        System.out.println("Waktu Sekarang (Format AM/PM)");

        System.out.println( time.Format12h() );

        System.out.println();

       

        try{

            time.setTime(99, 99, 99);

        }

        catch (IllegalArgumentException e){

            String pesan = String.format( "Exception: %s\n\n", e.getMessage());

            System.out.println(pesan);

        }

       

        System.out.println("Setelah percobaan pernyataan yang salah:");

        System.out.println("Waktu Sekarang (Format 24 jam)");

        System.out.println( time.Format24h() );

        System.out.println("Waktu Sekarang (Format AM/PM)");

        System.out.println( time.Format12h() );

        System.out.println();

    }

}
