LANGKAH-LANGKAH PRAKTIKUM

A. Manusia.java

//file Manusia harus berada dalam berada dalam folder makhlukhidup

package makhlukhidup;

public class Manusia{

            public String nama="";

            public Manusia(String nama){

                        this.nama=nama;

                        }

            }

B.  Tumbuhan.java

//file Tumbuhan harus beada dalam folder makhlukhidup

package makhlukhidup;

public class Tumbuhan{

            public String nama="";

            public Tumbuhan (String nama){

                        this.nama=nama;

            }

}

C. Burung.java

//file Burung harus berada dalam folder makhlukhidup/hewan

package makhlukhidup.hewan;

public class Burung{

            public static final boolean bisaTerbang=true;

            public String nama="";

            public Burung (String nama){

            this.nama=nama;

            System.out.println("Nama burung : "+nama);

            }

}

D. MainMakhlukHidup.java

//file MainMakhlukHidup harus berada dalam folder Meet6

public class MainMakhlukHidup {

            public static void main(String [] args){

                        makhlukhidup.Manusia m=new makhlukhidup.Manusia

("Sayuti");

            System.out.println("nama: "+m.nama);

            makhlukhidup.Tumbuhan t=new

makhlukhidup.Tumbuhan ("Palem");

            System.out.println("nama:"+t.nama);

            System.out.println("Semua burung pasti bisa terbang?" + makhlukhidup.hewan.Burung.bisaTerbang);

            makhlukhidup.hewan.Burung b=new

makhlukhidup.hewan.Burung("Beo");

            }

}

output :

E.  MainMakhlukHidupPakeImport.java

//file MainMakhlukHidup harus berada dalam folder Meet 6

import makhlukhidup.*;

import makhlukhidup.hewan.*;

public class MainMakhlukHidupPakeImport{

            public static void main (String [] args){

            Manusia m=new Manusia ("Sayuti");

            System.out.println("nama:"+m.nama);

            Tumbuhan t=new Tumbuhan("Palem");

            System.out.println("nama:"+t.nama);

            System.out.println ("Semua burung pasti bisa terbang           ?"+Burung.bisaTerbang);

            Burung b=new Burung("Beo");

}

}

F.  ContohString.java

public class ContohString {

            public static void main(String [] arqs) {

                        String Kalimat ="Selamat belajar JAVA";

                        System.out.println("toUpperCase    :   "+Kalimat.toUpperCase());

                        System.out.println("toLowerCase    :   "+Kalimat.toLowerCase());

                                    System.out.println("Jumlah Karakter : "+Kalimat.length());

                                    System.out.println("Karakter index ke 0  :  " +Kalimat.charAt(0));

                        System.out.println("substring(16,20)  :           " +Kalimat.substring(16,20));

                                    System.out.println("Karakter index ke 0  :  " +Kalimat.trim());

                                   

                                   

                        }

            }

output :

G. OpMatematika.java

public class OpMatematika {

public static void main(String[] arqs) {

System.out.println("E                                                                                = " +Math.E);

System.out.println("PI                                                                               = " +Math.PI);

System.out.println("Ln 20                                                                         = " +Math.log(20.0));

System.out.println("ceil(-5.6)                                                                    = " +Math.ceil(-5.6));

System.out.println("floor(-5.6)                                                                  = " +Math.floor(-5.6));

System.out.println("round(-5.6)                                                                = " +Math.round(-5.6));

System.out.println("sqrt(25)                                                                      = " +Math.sqrt(25));

System.out.println("pow(25,0.5)                                                               = " +Math.pow(25,0.5));

}

}
