    Question New to Java, need help with arrays inside a loop please!

    I'm coding a program that will take the prices entered by a user at a store and display them back within the program, so far I've completed the entire program except the part that takes the users input within a loops and prints it out as a array.

    What I need help with;

    The program has parameters whether ie. Adding anything over 3000 doesn't work, add a 0 removes the last price, and a -1 ends the program.

    After ending the program (using -1) I need to take the prices the user input and output it within an array, example:

    Enter a price for item #5: $-1
    -1 entered, calculating total owing…
    OK Gary, your purchases are:
    $19.99
    $12.50
    $17.43
    $78.33
    SUB-TOTAL: $128.25

    I don't know how to code an array so I take reprint the prices entered by the user within the loop, if anyone could help me I'd be greatly appreciated.

    Ok, so is your problem about creating the array or looping through the array at the end and printing out each element?

    My problem is looping through the array at the end and printing it out.

    The array I created is : ArrayList <Double> costList = new ArrayList<Double>(15);
    double [] priceArray = new double [15];

    The max amount of items that can go though is 15.
