INPUTAN PADA JAVA

Adalah perintah untuk memberikan nilai / input pada bahasa java. Dibagi menjadi 3, yaitu :

1. Input Stream : suatu perintah yang disediakan oleh java untuk melakukan proses input output (menggunakan java  io) dan memerlukan konversi .
2. Input B uffered Reader : suatu perintah yang disediakan oleh java untuk melakukan proses input output (menggunakan java  io), perlu penampung data untuk prosesnya, dan perlu konversi.

3. Input Scanner : suatu perintah yang disediakan oleh java yang menggunakan Java Utilities dan tidak perlu dikonversi.

Tugas 2 : Artikel Tentang Method dan Parameter beserta contoh dan latihannya

Method dan Parameter dalam JAVA

Method dan Parameter dalam JAVA
1.      Pengertian

1. Method

Method adalah implementasi operasi yang bisa di lakukan oleh Class dan Object atau bagaimana suatu class bekerja. Operasi – operasi yang dilakukan oleh method, diantaranya, yaitu :

1. Suatu Method bisa menerima dan memanipulasi data atau field didalam diri Method tersebut.
2. Suatu Method bisa mempengaruhi nilai suatu object lain.

Method  melakukan :

1. Memanipulasi data
2. Perhitungan matematika
3. Mengontrol proses
4. Memonitori kejadian dari suatu event

Untuk membuat atau menciptakan suatu method ada 4 bagian yang mendasar  yaitu:

1. Nama Method
2. Daftar parameter-parameter
3. Tipe objek atau tipe primitive ( tipe data ) yang di kembalikan method
4. Badan program method

Suatu method memiliki dua jenis di java :
a)     Method yang di sediakan di java itu sendiri, antara lain

• Println; pada System.out
• showMessageDialog () / showInputDialog () ; pada JoptionPane
• Nextlnt () ; pada fungsi Scanner
• Equals; pada String
• Etc

b)     Method yang dapat kita buat sendiri
Untuk membuat method yang di buat sendiri di java , sintaksnya yaitu ;
Modifier returnValueType Methodname(List parameters )
{
                 Statement;
}
2.   Parameter
Parameter merupakan bagian dari method yang mana di dalam suatu method bisa memiliki 1 parameter atau  lebih dari 1 parameter. Parameter itu sendiri adalah suatu bagian dari method yang mana harus di beri type data dan disini penulis menganggap suatu parameter mirip sekali dengan variable ( tetapi yang merupakan dalan bagian dari method ) yang bisa menentukan suatu nilai atau merubah suatu nilai nantinya saat di program java di jalankan ( Running )  atau di tampilkan dengan method yang sudah ada di java.

 2.     Membuat suatu program
Contoh coding dan tampilan dari program segitiga bintang bernilai 4 ( Looping )
1. Tampilan Program








2. Coding dari Program membuat program segitiga bintang bernilai 4 ( Looping ) :
public class cetakbintang{
public static void bintang()
{
for(int i=6;i >=1;i–){
for(int j=i;j >=1;j–){
System.out.print(“*”);
}
System.out.println();
}
}
public static void main(String[]args)
{
System.out.println(” Segitiga Bintang bernilai 4″);
System.out.println();
bintang();
}
}
Selain contoh dengan listing ( Looping ) di atas penulis juga membuat dengan coding yang lain tetapi menghasilkan tampilan yang sama:
1. Tampilan

codingnya adalah :
2. Coding
public class cetakbintang1{
public static void bintang()
{
for(int i=1;i <=6;i++){
for(int j=i;j <=6;j++){
System.out.print(“*”);
}
System.out.println();
}
}
public static void main(String[]args)
{
System.out.println(” Segitiga Bintang bernilai 4″);
System.out.println();
bintang();
}
}
3. Membuat kalkulator sederhan yang berisi metod dan parameter serta mengeksekusinya
1. Tampilan





2. Coding dari Class Kalkulator:
/**
* @(#)kalkulator.java
*
*
* @author
* @version 1.00 2012/3/25
*/
public class kalkulator {
int operan1;
int operan2;
int operan3;
int operan4;
int hitung()
{
return operan1+operan2;
}
void hitung (int operan1,int operan2)
{
operan1=operan1;
operan2=operan2;
operan3=operan3;
operan4=operan4;
}
}
3. Coding untuk pengeksekusian dari kalkulator tersebut :
/**
* @(#)kalkulator beraksi.java
*
*
* @author
* @version 1.00 2012/3/25
*/
public class kalkulatorberaksi {
public static void main(String[]arg){
kalkulator kalkulator1 = new kalkulator();
int tambah;
int kurang;
kalkulator1.operan1=30;
kalkulator1.operan2=30;
kalkulator1.operan3=20;
kalkulator1.operan4=10;
System.out.println();
tambah = kalkulator1.operan1+ kalkulator1.operan2;
kurang= kalkulator1.operan3-kalkulator1.operan4;
System.out.println(“Contoh Kalkulator Sederhana yang menggunakan method dan paramater :”);
System.out.println(” Pertambahan= 30+30=”+tambah);
System.out.println(” Pengurangan= 20-10=”+ kurang);
}
}

Tugas No. 2
Listing:

public class SegitigaBintang{
     public void printInitialization(){
        System.out.println("General Output");
        System.out.println("------------------------------
Configuration: <Default> -----");
     }
    
     public void printTriangle(final int count){
       System.out.println("Segitiga bintang bernilai " + String.valueOf(count));
      
       int i;
       for(i=count; i> 0; i--){
        for(int j=0; j<i; j++) {
          System.out.print(" * ");
        }
         System.out.print("\n");     
       }
     }

     public static void main(String []args){
        final int count = 4;
    SegitigaBintang obj = new SegitigaBintang();
    obj.printInitialization();
    obj.printTriangle(count);
     }
}

     class Kalkulator{
       public void pertambahan(final int ops1, final int ops2){
       final int hasil = ops1 + ops2;
         System.out.println("Pertambahan : " + String.valueOf(ops1 + " + " + String.valueOf(ops2) + " = " + String.valueOf(hasil)));
       }
     
       public void pengurangan(final int ops1, final int ops2){
        final int hasil = ops1 - ops2;
         System.out.println("Pengurangan : " + String.valueOf(ops1 - " + " + String.valueOf(ops2) + " = " + String.valueOf(hasil)));
       }
     }
    
     public static void main(String []args){
        final int operand1 = 30;
        final int operand2 = 20;
        final int operand3 = 10;
    KalkulatorBeraksi obj = new KalkulatorBeraksi();
    KalkulatorBeraksi.Kalkulator obj2 = obj. new Kalkulator();
    obj2.pertambahan(operand1, operand1);
    obj2.pengurangan(operand2, operand3);
