    Default Need a different way to add Cubed numbers 1-10

     * Put your documentation header here.
    import java.util.Scanner;
    public class Lab5{
         * Returns an integer whose value is a^3 (a cubed).
         * @param any integer to be cubed
         * @return a^3 (a cubed)
        public static int cubed(int a){
            int cube = a * a * a;
            return cube;
        /* Answer the following questions about the method cube: 
         *1) What is the method's return type?  
         *2) What is the method's formal parameter name?
         *3) What is the cube method's signature?
             int a
         *4) What line of code invokes the cube method?
              Return Cube
         *5) What is the name of the argument passed to cube?
         */ //Cubed
        public static void main(String[] args) {
           Scanner in = new Scanner(System.in);
           System.out.println("Enter an integer");
           int x = in.nextInt();
           // invoking the cubed method
           System.out.println("The cubed value of "+ x + " is "
                   + Lab5.cubed(x)+".");
           /* Below this comment, write a piece of code that will sum the cubes
            * 0f all the numbers from 1 to 10 inclusive. 0utput this sum (labelled).
        int a = 1;
        int b = 2*2*2;
        int c = 3*3*3;
        int d = 4*4*4;
        int e = 5*5*5;
        int f = 6*6*6;
        int g = 7*7*7;
        int h = 8*8*8;
        int i = 9*9*9;
        int j = 10*10*10;
        System.out.println("Sum of Cubed Numbers of 1-10:  "+a + b + c + d + e + f + g + h + i + j);
     * Copy and paste your program output here

    The last part with int a-j......
    Is there a better way of doing this, like possibly putting into a loop and showing output from maybe a single piece of information? I hope im asking this question right.....

    --- Update ---

    Or really is there a better way of adding them up.... to reduce coding

    Yes, there is a better way. Try your loop idea and see what happens.

    Why do most of your answers to questions 1 - 5 have incorrect capitalization?

    capitalization doesn't really matter... just answering the question.

    ummm.... as far as the loop goes,

    I'm not very keen on the loop idea but I'll do a little more reading and find out.
