    Default how do i loop this simple java code?

    for example if i input 2 it would go straight to option 2 and then if i press 1 it would go to option 1. from there i want to be able to go to any other option without the program stopping. help would be greatly appreciated


    Scanner sc = new Scanner(System.in);
    Account chequingAcc = new ChequingAccount();
    System.out.println("Please enter your Unique Number");
    chequingAcc.setuniqueString(sc.nextLine(
    System.out.println("verefied, what would you like to do?");
    System.out.println("to check balance press 1");
    System.out.println("to debit account press 2");
    System.out.println("to credit account press 3");
    System.out.println("to overdraft account press 4");
    System.out.println("to exit press 5");
    int k = sc.nextInt();
    if(k<=0 ||k>5){
    System.out.println("invalid ");
    k =sc.nextInt();
    }

    while( k==1){
    System.out.println("--------------------
    System.out.println("Chequing Account current balance is $" + chequingAcc.getbalance());
    System.out.println("what you like do now?");
    System.out.println("to debit account press 2");
    System.out.println("to credit account press 3");
    System.out.println("to overdraft account press 4");
    System.out.println("to exit press 5");
    k =sc.nextInt();


    while (k==2){
    System.out.println("--------------------
    System.out.println("enter ammount to debit to Chequing Account");
    chequingAcc.setDebit(sc.nextDouble());
    System.out.println("Chequing Account current balance is $" + chequingAcc.getbalance());
    System.out.println("what you like do now?");
    System.out.println("to check balance press 1");;
    System.out.println("to credit account press 3");
    System.out.println("to overdraft account press 4");
    System.out.println("to exit press 5");
    k =sc.nextInt();

    while(k==3){
    System.out.println("--------------------
    System.out.println("enter the ammount to credit to Chequing Account");
    chequingAcc.setCredit(sc.nextDouble());
    System.out.println("Chequing Account current balance is $" + chequingAcc.getbalance());
    System.out.println("what you like do now?");
    System.out.println("to check balance press 1");;
    System.out.println("to debit account press 2");
    System.out.println("to overdraft account press 4");
    System.out.println("to exit press 5");
    k =sc.nextInt();

    while(k==4){
    System.out.println("--------------------
    System.out.println("enter the ammount to overDraft to Chequing Account");
    chequingAcc.setoverDraft(sc.nextDouble()
    System.out.println("Chequing Account current balance is $" + chequingAcc.getbalance());
    System.out.println("what you like do now?");
    System.out.println("to check balance press 1");;
    System.out.println("to debit account press 2");
    System.out.println("to credit account press 3");
    System.out.println("to exit press 5");
    k =sc.nextInt();

    while(k==5){
    System.out.println("thank for using the bank");
    System.exit(0);


    }
    }
    }
    }





    }
    }
    }

    Default Re: how do i loop this simple java code?

    Put the code you want to repeat inside of a loop. Since time to end the loop will be determined by user input, use a while loop with a condition that tests what the user entered to see if if should continue looping.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    Be sure to properly format the code so that all statements do NOT start in the first column. Nested statements should be indented.
    If you don't understand my answer, don't ignore it, ask a question.
