    Default Need assistance with Returning Value Methods

    Here is the code that I have thus far...I am a novice and completely stuck. The objectives that I must complete are as follows:

    1.) Write a method called calcTotalPrice which takes two parameters:

    -Quantity of an item

    -Price of an item

    (calcTotalPrice will return the amount needed to buy that quantity at that price.)

    2.) Write a main method that asks the user for 3 different items, the desired quantity and the price of each item. Call calcTotalPrice to calculate the total price of each item. Use String.printf to format the output.





    for(int i=0; i<=3; i++){
    quantity1 = JOptionPane.showInputDialog("Hello, please enter the quantity of Item"+i);
    Integer.parseInt(quantity1);
    price1 = JOptionPane.showInputDialog("Hello, please enter the quantity of Item"+i);
    java

    Hi,

    Please be more specific. What exactly are you stuck on, and what have you tried? And please post the complete code (inside code tags); I can't tell whether you've defined the 'quantity1' and 'price1' variables before trying to use them.

    One definite problem though is you're not doing anything with the return value from Integer.parseInt(quantity1). You'll need new int variables for both quantity and price, assigned to the return value from Integer.parseInt(). Then you'll have the two ints needed to multiply.
