Coding Akar dan Pakar dengan Java

Sewaktu saya kuliah semester 1 kemarin, teman saya mendapat Final Project dari Lab.Praktikum untuk membuat Akar dan Pangkat yang berbasis Java.
kebetulan saya yang tidak mendapatkan tugas itu ingin mencoba untuk membuat seperti yang teman saya buat dan hasilnya pun memuaskan. Untuk itu saya ingin berbagi tentang hasil pekerjaan saya ini.
Semoga berhasil....!!!!

public class kuadrat {
    public static void main(String[] args) {

    String pilihan = "";
    int pil = 0;
    pilihan = JOptionPane.showInputDialog("Pilih 1 untuk akar & pilih 2 untuk");
    pil = Integer.parseInt(pilihan);

Stack Java Source Code

Salah satu konsep yang sangat bermanfaat dalam ilmu komputer adalah Stack.

Stack adalah koleksi item/ data yang terurut dimana item baru akan dimasukkan atau item lama akan dihapus melalui ujung/ jalan.

Stack bersifat dinamis artinya item/data yang tidak terpakai bisa dihapus.

Dibawah ini adalah contoh Source Code nya:

Semoga bermanfaat....

:)

import java.io.*;
import java.util.*;

public class stack{
Stack stack;
String str;
int num, n;
public static void main(String[] args){
    stack q = new stack();
}
public stack(){
    try{
    stack = new Stack();

    System.out.println("===============");
    System.out.println("===============");
    System.out.println("+++++Stack+++++");
    System.out.println("------In-------");
    System.out.println("+++++Java++++++");
    System.out.println("===============");
    System.out.println("===============");
    System.out.println();
    System.out.print("masukkan array nya : ");
    str = bf.readLine();
    num = Integer.parseInt(str);
    for(int i = 1; i <= num; i++){

String pesan_input = "1. penjumlahan\n2. pengurangan\n3. perkalian\n4. pembagian\nmasukkan pilihan anda !!!! ";
String c1 = JOptionPane.showInputDialog(pesan_input);
String a1 = JOptionPane.showInputDialog(" Masukkan nilai pertama");
String b1 = JOptionPane.showInputDialog(" Masukkan nilai kedua ");

double hasil;

double a2 = Double.parseDouble(a1);
double b2 = Double.parseDouble(b1);
int c2 = Integer.parseInt(c1);

switch(c2){
case 1 : hasil = a2+b2;
JOptionPane.showMessageDialog(null,"Hasil ="+ hasil);
break;
case 2 : if(a2>b2){
hasil =a2-b2;
}else{hasil = b2-a2;}
JOptionPane.showMessageDialog(null,"Hasil ="+ hasil);
break;
case 3 : hasil = a2*b2;
JOptionPane.showMessageDialog(null,"Hasil ="+ hasil);
break;
case 4 : hasil =a2/b2;
JOptionPane.showMessageDialog(null,"Hasil ="+ hasil);
break;
