Tugas Kelompok ke 1 (Minggu 2 / Sesi 4)

1. Perhatikan source code program lakukan modifikasi pada program tersebut dengan kriteria berikut ini : a. Semua bilangan ditampilkan dengan dua angka sehingga menghasilkan output  barisan bilangan yang lebih tertata rapi seperti tampilan ini 02 18 34 50 66 82

04 20 36 52 68 84

06 22 38 54 70 86

08 24 40 56 72 88

10 26 42 58 74 90

12 28 44 60 76 92

14 30 46 62 78 94

16 32 48 64 80 96

 b. Serupa dengan (soal a), namun tampilan dibalik  menjadi  menjadi seperti ini 16 32 48 64 80 96

14 30 46 62 78 94

12 28 44 60 76 92

10 26 42 58 74 90

08 24 40 56 72 88

06 22 38 54 70 86

04 20 36 52 68 84

02 18 34 50 66 82

2. Melanjutkan program pada soal (nomor.1b) Buatlah progam Array dengan asumsi  bahwa output program diatas menjadi data bagi program Array, Kemudian program Array akan menghitung berapa jumlah semua bilangan didalam Array tersebut.

LAMPIRAN program : public class StringBuffer StringBuffer{ { public static void void main  main( (String String[] [] args  args) ) { countTo_N_Improved(); countTo_N_Improved (); } private final static int int MAX_LENGTH  MAX_LENGTH= =30 30; ; private static String String buffer  buffer = "" ""; ; private static void void emit  emit( (String String nextChunk  nextChunk) ) { if( if (buffer buffer. .length length() () + nextChunk  nextChunk. .length length() () > MAX_LENGTH  MAX_LENGTH) ) { System. System .out out. .println println( (buffer buffer); ); buffer = "" ""; ; } buffer += += nextChunk  nextChunk; ; } private static final int int N  N= =100 100; ; private static void void    countTo_N_Improved() countTo_N_Improved () { for (int int count  count= =2; count<=N  count<=N; ; count  count= =count count+ +2) { emit( emit (" " + count  count); ); } } }

ANSWER 1a. package TugasTeam4 /** * * @author TEAM 4 */ public class tugas1a{ public static void main(String[] args) { countTo_N_Improved (); }

//Blok script agar tampilan rapi private final static int MAX_LENGTH=25; private static String buffer = ""; private static void emit(String nextChunk) { if(buffer.length() + nextChunk.length() >   MAX_LENGTH) { System.out.println(buffer); buffer = ""; }

buffer += nextChunk; }

//Blok untuk menampilkan angka dibawah seratus kelipatan 2 private static final int N=100; private static void  countTo_N_Improved() { for (int count=2; count <=N; count=count+2) { if (count <10) emit(" 0" + count) else

emit(" " + count); } } }

2. package TugasTeam4; /** * * @author Team 4 */ public class tugasno2 { /** * @param   args the command line arguments */ public static void main(String[] args) { countTo_N_Improved (); String[] count = ember.split(" "); int total = 0; for(int num=2;num <=96;num++) { if((num!=2)&&(num%2==0)) total = total + num; }; System.out.println("\nTotal jumlah semua bilangan adalah " + total);

//Menghitung total semua bilangan System.out.println("Total bilangan yang ditampilkan adalah : "+(count.length-1)); // dikurang 1 karna ada spasi }
