Program Java Menggunakan Swing

import javax.swing.*;
public class Swing
{
public static void main (String[] args)
{
int i,pjg;

System.out.println ("-----> INPUT <-----");
System.out.println ();


pjg = Integer.parseInt(JOptionPane.showInputDialog("Jumlah Mahasiswa"+" "+":"));

int uts [] = new int [pjg];
int uas [] = new int [pjg];
int tugas [] = new int [pjg];
int nilai [] = new int [pjg];
String nama [] = new String [pjg];


for (i=0; i< pjg ; i++)
{
nama [i]= JOptionPane.showInputDialog("Masukkan Nama"+" "+":");
System.out.println("Nama : " + nama[i]);

uts [i]= Integer.parseInt(JOptionPane.showInputDialog("Masukkan Nilai UTS"+" "+":"));
System.out.println("UTS : " + uts [i] );

uas [i]= Integer.parseInt(JOptionPane.showInputDialog("Masukkan Nilai UAS"+" "+":"));
System.out.println("UAS : " + uas [i] );

tugas [i]= Integer.parseInt(JOptionPane.showInputDialog("Masukkan Nilai Tugas"+" "+":"));
System.out.println("Tugas : " + tugas [i]);

nilai [i]=(4*uts[i])/10 + (4*uas[i])/10 + (2*tugas[i])/10;

System.out.println ();
}


System.out.println ("-----> OUTPUT <-----");
System.out.println ();

Program Java menggunakan Array (Larik)

import java.io.*;
public class Array
{
public static void main (String [] args)throws IOException
{
int i, pnjng;

BufferedReader Ms = new BufferedReader (new InputStreamReader (System.in));

System.out.println ("-----> INPUT <-----");
System.out.println ();
System.out.print ("Jumlah Mata Kuliah : ");
pnjng = Integer.parseInt (Ms.readLine ());

int [] bil = new int [pnjng];
String [] K = new String [pnjng];
for ( i=0; i< pnjng ; i++)
{
bil [i] = i + 1 ;
System.out.print ("Mata Kuliah ke - "+ bil [i] + " : " );
K [i] = Ms.readLine ();
}
System.out.println ();
System.out.println ("-----> OUTPUT <-----");
System.out.println ();
System.out.println ("Nama Mata Kuliah :");

for ( i=0 ; i< pnjng ; i++)
System.out.println (bil [i] + ". " + K[i]);
}
}

Hasilnya adalah:
-----> INPUT <-----

Jumlah Mata Kuliah : 4
Mata Kuliah ke - 1 : ALGORITMA 2
Mata Kuliah ke - 2 : TEORI ORGANISASI
Mata Kuliah ke - 3 : LOGIKA MTK 2
Mata Kuliah ke - 4 : BAHASA INGGRIS 2

-----> OUTPUT <-----

Nama Mata Kuliah :
1. ALGORITMA 2
2. TEORI ORGANISASI
3. LOGIKA MTK 2
4. BAHASA INGGRIS 2


Alhamdulillah yah akhirnya ini tugas selesai. Ngerjain nya bikin pusing 7 keliling tapi dengan doa dan usaha . Akhirnya selesai ^.^

OK. disini saya mau berbagi ilmu tentang membuat sebuah program java dengan bahasa c++.
cara nya gampang yaitu dengan mennggunakan sub perulangan:

public class SubPerulanganBintang
{
public static void main (String [] args)
{
int i,j;
for (i=1; i<=5; i++)
{
for (j=1; j<=i; j++)
{
System.out.print ("*");
}
System.out.println();
}

for (i=4; i>=1; i--)
{
for (j=1; j<=i; j++)
{
System.out.print ("*");
}
System.out.println ();
}
}
}

OK SELAMAT MENCOBA YA ^.^
semoga ilmu ini bermanfaat ^.^
