10. Operasi Tipe Data
Operator Penggunaan Deskripsi
+ Op1+op2 Op1 ditambah op2
- Op1-op2 Op1 dikurang op2
* Op1*op2 Op1 kali op2
/ Op1/op2 Op1 dibagi op2
% Op1%op2 Sisa dari op1 dibagi op2
++ Op++ Increment nilai op sebesar 1, evaluasi
sebelum increment
++ ++op Increment nilai op sebesar 1, evaluasi
setelah increment
-- Op-- Decrement nilai op sebesar 1

public static void main(String args[]){
int a=5;
System.out.println(a);
System.out.println(a++);
System.out.println(++a);
int b=5;
System.out.println(b);
System.out.println(++b);
System.out.println(b);
}
}

System.out.println(“Ibu tetap pergi ke
pasar.”);
}
}
}

14. Program Array
public class ProgramArray {
public static void main(String args[]){
int[] c = new int[5];
c[0] = 1;
c[1] = 2;
c[2] = 3;
c[3] = 4;
c[4] = 5;
for(int i=0;i<5;i++){
System.out.println(“Aray c ke-”+i+” adalah ”+c[i]);
}
}
}

15. Program Expressions, Statements, dan
Blocks
public class OperatorExp {
public static void main(String args[]){
double c = 2.0;
System.out.println(“C = ” + c);
int a = 0;
int b = 2;
int d = 4;
int hasil = 0;
hasil = a+b*d;
System.out.println(“Hasil = ” + hasil);
hasil = (a+b)*d;
System.out.println(“Hasil = ” + hasil);
}
}
Sesi 2 - Java Application Developer

16. Program Expressions, Statements, dan
Blocks
public class OperatorExp {
public static void main(String args[]){
double c = 2.0;
System.out.println(“C = ” + c);
int a = 0;
int b = 2;
int d = 4;
int hasil = 0;
hasil = a+b*d;
System.out.println(“Hasil = ” + hasil);
hasil = (a+b)*d;
System.out.println(“Hasil = ” + hasil);
}
}
Sesi 2 - Java Application Developer

17. Fungsi & Prosedur
Fungsi = meminta hasil / memberikan balikan
Prosedur = method yang tidak mengembalikan hasil.
tipe_data nama_fungsi(param1,param2,....param_n){
//statement yang akan dieksekusi
return nilai_balik;
}
void nama_prosedur(param1,param2,....param_n){
//statement yang akan dieksekusi
}
Sesi 2 - Java Application Developer

18. Program Fungsi
public class Fungsi {
static int hasil;
static int tambah(int a, int b){
int c;
c = a + b;
return c;
}
public static void main(String args[]){
int a=5;
int b=6;
hasil = tambah(a,b);
System.out.println(“Hasil Penjumlahan ” + a + “ dan ” + b + “ adalah
” + hasil);
}
}
