We Keep Coding

Data calculations excluded within switch statement loop

My final project for class is a text based game. So far I have it working how I want, except for 1 or 2 issues. First big issue is when I enter my "magic" menu (switch statement loop) none of the data has any impact. Meaning if the user's HP drops below 0, they don't die, it doesn't happen until you exit the loop. I've messed with it, and made it work, but it broke other parts of the code, so please help if you can.
Another solution I was able to do was setting the boolean value to false after each case, making the user enter a case, then it jumps out of the switch, which works great, except it executes the entire switch loop, meaning every single input.
Here's the main code, keep in mind it has another class

How to create a loop that will attack an enemy until the enemy is dead

I am just 2 months into programming so I apologize for my poorly written code. I appreciate it if you will give me tips and advice on how i can improve my code.
I created a program that creates a hero.(in this case I used dota heroes)
The program starts by asking The hero name, Health pool, mana pool, attack speed and attack damage.
after I created a method that will ask a user what type of hero it is.
the selection are 1. Strength 2. Agility 3. Intelligence. Each selection will set the hero's attack damage per level, attack speed per level, Hp per level and mp per level.
after this, the program will then ask a user to choose a level(max level is only 25)
after selecting the level the program will display the new attributes after leveling up. for example if the user chooses 25 then Healthpool = healthpool + (hp per level * selected level) and etc.
After this the program will then show a selection of enemies in this example is tower and roshan.
after the user chooses an enemy the program will then show an option on what to do such as 1. attack 2. end.
What I want to happen is when the user chooses to attack, I want the program to show the current hp of the tower after attacking then will go back to the options on what to do.
I really do not know what loop should I do.

It's been more than a year, and I've just stumbled onto this question.
You probably don't need an answer anymore, but if you happen to need it i am making a game that involves enemies attacking each other until someone dies.
Here's a snippet for what I'm using for a Player1 attacking a Player2:
new Thread(new Runnable() {
#Override
public void run() {
do {
try {
System.out.println("DELAYING " + (long) game.getAttackDelay(finalPlayer1));
Thread.sleep((long) game.getAttackDelay(finalPlayer1));
float p1DamageDealt = game.fight(finalPlayer1, finalPlayer2);
game.setCurrentHp(finalPlayer2, p1DamageDealt);
if (game.getCurrentHp(finalPlayer1) <= 0 || game.getCurrentHp(finalPlayer2) <= 0) {
break;
}
sendToPlayerOne.writeObject("YOU DEALT " + p1DamageDealt + "!");
sendToPlayerTwo.writeObject("YOU TOOK " + p1DamageDealt + "!");
sendToPlayerOne.writeObject("ENEMY HAS " + game.getCurrentHp(finalPlayer2) + " HP LEFT!");
sendToPlayerTwo.writeObject("YOU HAVE " + game.getCurrentHp(finalPlayer2) + " HP LEFT!");
//sendToPlayerOne.writeObject(p1DamageDealt);
} catch (InterruptedException | IOException ex) {
Logger.getLogger(Server.class.getName()).log(Level.SEVERE, null, ex);
}
} while (finalPlayer1.getCurrentHp() > 0 && finalPlayer2.getCurrentHp() > 0);
if (finalPlayer1.getCurrentHp() <= 0 && finalPlayer2.getCurrentHp() > 0) {
gameResult = "YOU LOSE!";
} else if (finalPlayer2.getCurrentHp() <= 0 && finalPlayer1.getCurrentHp() > 0) {
gameResult = "YOU WIN!";
} else {
gameResult = "IT'S A TIE!\n"
+ "Your HP : " + finalPlayer1.getCurrentHp() + "\n"
+ "Enemy HP:" + finalPlayer2.getCurrentHp();
}
try {
sendToPlayerOne.writeObject(gameResult);
} catch (IOException ex) {
Logger.getLogger(Server.class.getName()).log(Level.SEVERE, null, ex);
}
}
}).start();
It's not very good but works for what I need, and probably will work for you with some adjustments, since the basics for this to work is just do a "do X(attack) while Y(enemy health is not 0)"

You have an unconditional break right before the switch in question.
As an aside, I think this is the perfect time to learn about functions and how to use them to make code more modular.

Unexpected result in if else statement

I'm a beginner, so this result I am getting for one condition of my if else statement is blowing my mind. Everything works properly except for the condition when the QtyCalc variable is >= 100. The Finprice variable is listed as the disc variable and I can't figure out why. Help?
import javax.swing.JOptionPane;
public class SoftwareSales {
public static void main(String[] args) {
final int price = 99;
String Qty;
double QtyCalc, preprice, Finprice, disc;
Qty = JOptionPane.showInputDialog(null, "How many packages will you buy?");
QtyCalc = Double.parseDouble(Qty);
preprice = QtyCalc * price;
if (QtyCalc >= 100) {
disc = (preprice * (0.5));
Finprice = (preprice - disc);
JOptionPane.showMessageDialog(null, "Your discount is: " + disc + ".\n" + "Your final price is: " + Finprice + ". ");
} else if (QtyCalc >= 50 && QtyCalc <= 99) {
disc = (preprice * 0.4);
Finprice = (preprice - disc);
JOptionPane.showMessageDialog(null, "Your discount is: " + disc + ".\n" + "Your final price is: " + Finprice + ". ");
} else if (QtyCalc >= 20 && QtyCalc <= 49) {
disc = (preprice * 0.3);
Finprice = (preprice - disc);
JOptionPane.showMessageDialog(null, "Your discount is: " + disc + ".\n" + "Your final price is: " + Finprice + ". ");
} else if (QtyCalc >= 10 && QtyCalc <= 19) {
disc = (preprice * 0.2);
Finprice = (preprice - disc);
JOptionPane.showMessageDialog(null, "Your discount is: " + disc + ".\n" + "Your final price is: " + Finprice + ". ");
} else if (QtyCalc < 10 && QtyCalc >= 1) {
disc = 0;
Finprice = 0;
JOptionPane.showMessageDialog(null, "Sorry, there is no discount for purchases less than 10." + " Your price is: " + preprice);
} else {
JOptionPane.showMessageDialog(null, "You have entered an invalid number.");
}
disc = 0;
Finprice = 0;
System.exit(0);
}
}

The final price is equal to the discount when the quantity is >= 100 because the discount is 50% ... look at the code that you posted. In particular:
if (QtyCalc >= 100) {
disc = (preprice * (0.5));
Finprice = (preprice - disc);
JOptionPane.showMessageDialog(null, "Your discount is: " + disc + ".\n" + "Your final price is: " + Finprice + ". ");
}

There is no strange behavior, just simple math:
disc = (preprice * (0.5));
Finprice = (preprice - disc);
you should also consider eliminating redundant code:
import javax.swing.JOptionPane;
public class SoftwareSales {
public static void main(String[] args) {
final int PRICE = 99;
String qty;
double qtyCalc, preprice, finprice, disc;
disc = 0;
qtyCalc = 0;
boolean invalid = false;
do{
invalid = false;
qty = JOptionPane.showInputDialog(null, "How many packages will you buy?");
if (qty == null){
return;
}
try{
qtyCalc = Double.parseDouble(qty);
}catch(NumberFormatException e){
invalid = true;
}
}while(invalid);
preprice = qtyCalc * PRICE;
if (qtyCalc >= 100) {
disc = (preprice * (0.5));
} else if (qtyCalc >= 50 && qtyCalc <= 99) {
disc = (preprice * 0.4);
} else if (qtyCalc >= 20 && qtyCalc <= 49) {
disc = (preprice * 0.3);
} else if (qtyCalc >= 10 && qtyCalc <= 19) {
disc = (preprice * 0.2);
} else if (qtyCalc < 10 && qtyCalc >= 1) {
disc = 0;
finprice = 0;
JOptionPane.showMessageDialog(null, "Sorry, there is no discount for purchases less than 10. Your price is: " + preprice);
return;
} else {
JOptionPane.showMessageDialog(null, "You have entered an invalid number.");
return;
}
finprice = (preprice - disc);
JOptionPane.showMessageDialog(null, String.format("Your discount is: %.2f.\nYour final price is: %.2f. ",disc,finprice));
}
}
Also remember the java-convention for variables: always begin with lower-case.
finals alsways IN UPPER-CASE
