Coding Java “Bilangan Prima”

Selamat mencoba yh kawan 🙂

 

 

import javax.swing.*;

public class BilanganPrima {

public static void main(String[] args) {

int angka,pembagi,bil=2,counter=1;

boolean Prima;

String input;

JOptionPane.showMessageDialog(null,”       Program Identifikasi Bilangan Prima”,”Welcome”,JOptionPane.PLAIN_MESSAGE);

input=JOptionPane.showInputDialog(“Masukkan …angka :”);     angka=Integer.parseInt(input);

while(counter<=1000){

Prima=true;

for (pembagi = 2; pembagi <= bil/2; pembagi++){

if (bil % pembagi == 0){

Prima = false;

break;

}

}

if(Prima){

if(angka==bil){

JOptionPane.showMessageDialog(null,”Bilangan Prima”,”Hasil”,JOptionPane.INFORMATION_MESSAGE);                                           System.exit(0);

}

counter++;

}

bil++;

}

JOptionPane.showMessageDialog(null,”Bukan Bilangan Prima”,”Hasil”,JOptionPane.ERROR_MESSAGE);

System.exit(0);

}}

 

Jangan lupa di coment yah guys 🙂 thx

Coding Java “String gabung”

Selamat mencoba yah Guys!!! 🙂

public class StringGabung {
public static void main (String []rizky) {
String String1 = ” Penonton ” ;
String String2 = ” Menghadiri ” ;

StringGabung = String1 + String2 + String3;
System.out.println(StringGabung);
int anggota = 80;
StringGabung = ” Empat puluh empat adalah ” + 4 + 4;
System.out.println(StringGabung);
StringGabung = 10 + 10 + ” adalah dua puluh ” ;
System.out.println(StringGabung);
}
}

codingan java “identitas”

Codingan ini untuk membuat sebuah identitas, ini merupakan coding java yang cukup sederhana bagi pemula… 🙂

Selamat mencoba 🙂

class identitas {
String nama;
String kelas;
String praktikum;
String baris;
void Biodata () {
System.out.println (“Biodata saya”);
}
public static void main (String []args) {
identitas IdentitasSaya=new identitas ();
IdentitasSaya.nama=”Nama saya Handrian Agustinus”;
System.out.println(IdentitasSaya.nama);
IdentitasSaya.kelas=”Kelas 1IA11″;
System.out.println(IdentitasSaya.kelas);
IdentitasSaya.praktikum=”Praktikum Algoritma & Pemrograman”;
System.out.println(IdentitasSaya.praktikum);
IdentitasSaya.baris=”Baris B05″;
System.out.println(IdentitasSaya.baris);
IdentitasSaya.Biodata ();
}
}
