    Default Bank System Simulator

    I have a problem with my code. When I get prompted if i want to deposit, withdraw, or view my balance I type balance and it shows me the balance but they shows code that I also have in place and says "Unknown command", how do I stop this? Thank you. Here is the code:

    import java.util.Scanner;
    import java.util.Random;
     
    public class bankSystem {
    	public static void main(String[] args) {
    		Scanner kb = new Scanner(System.in);
    		double balance = 100;
    		int password;
    		double bankBalance;
    		double interest = .01;
    		int withdrawDeposit;
    		String withdrawDepositAnswer = null;
    		int withdrawAmount;
    		int depositAmount = 0;
    		Random rng = new Random();
    		int randomInt = rng.nextInt(100);
    		String name;
     
    		System.out.println("Enter name to recieve password!");
    		name = kb.next();
     
     
    		System.out.println("Your randomly generated password is : "
    				+ randomInt);
    		for (int idx = 1; idx <= 10; ++idx) {
     
     
     
    		}
    		password = randomInt;
    while(true){
    		System.out
    				.println("Hello, welcome to the bank! Please enter password to access account.");
    		password = kb.nextInt();
    		if (password == randomInt) {
    			System.out
    					.println("Welcome to your account! Would you like to withdraw, deposit, or view your balance?");
    			withdrawDepositAnswer = kb.next();
    			if (withdrawDepositAnswer.equalsIgnoreCase("balance")) {
    				System.out.println("$" + balance);
     
    			}
    			if (withdrawDepositAnswer.equalsIgnoreCase("Withdraw")) {
    				System.out.println("How much would you like to withdraw?");
    				withdrawAmount = kb.nextInt();
    				if (withdrawAmount > balance) {
    					System.out
    							.println("Sorry you don't have enough money left for that!");
    					return;
    				} else if (balance > withdrawAmount) {
    					balance = balance - withdrawAmount;
    				}
     
    				System.out.println("Your remaining balance is $ " + balance);
    			} else if (withdrawDepositAnswer.equalsIgnoreCase("Deposit")) {
    				System.out.println("How much would you like to deposit?");
    				depositAmount = kb.nextInt();
    				balance = balance + depositAmount;
    				System.out.println("Your new balance is $ " + balance);
     
    			} else {
    				System.out.println("Unknown command.");
     
    			}
    		} else {
    			System.out.println("Access Denied.");
    		}
     
     
     
     
     
    		}
     
    	}
    }

    Please copy the full contents of the command prompt window that shows what you are describing and paste it here.

    On windows: To copy the contents of the command prompt window:
    Click on Icon in upper left corner
    Select Edit
    Select 'Select All' - The selection will show
    Click in upper left again
    Select Edit and click 'Copy'

    Paste here.


    Hint: Add the value that is "unknown" to the error message so you can see what the computer sees when it executes the code.

    We crossed while I added to my post:

    Please copy and paste the text, no images. Text can't be copied from images for responses and text is easier to read.

    Strange when I run the code I get this question first:
    Enter name to recieve password!
    Your randomly generated password is : 35
    Why doesn't the command prompt window's contents you posted show that?


    Also you are ignoring this:

    Hint: Add the value that is "unknown" to the error message so you can see what the computer sees when it executes the code.
