6.1 How to store 300 values in your program?

A. Introduction

Suppose you are in a large high school and there are 300 students in your class. Even though each of you know your own height, the school administration wants to know the average height of this class and the tallest student.


Similarly, sometimes you might want to find out the average price of all 5-seat SUVs, as well as the most expensive or inexpensive one etc.


This type of problems involves handling a relatively large amount of values in your program. You can not create individual variables to store them. What to do?


B. Watch how to create an array ... ( Slides )




C. Now, please try the following in your IDE and save your project for the following sessions.

  1. Create a double array of 300 elements, name it height.

  2. Is there another way to declare an array? If you print out height[0], what value will be printed? what value is height[2] or height[299]? height[300] ? Try to print all of these and explain why you get what you see.


D. See if you can beat everyone else in this Kahoot! Or see if how many mistakes you can spot in these slides.


E. Feel free to post questions below.

    7.6 Can a function return an array?

    Discussion 
    A. Introduction A function can take a 1-D or 2-D array as input and manipulate the data elements. Once the function finishes processing, how to return the new array back to the caller? B. How to reflect a 2-D array vertically as shown below? i.e. turn A into B by moving the top row to the bottom, 2nd row to the 2nd but last... etc? class Reflect2DArray { public static int[][] verticalReflect(int[][] arrayX){ // Swap rows up and down int[][] temp = new int[arrayX.length][arrayX[0].length]; for (int row = 0; row < arrayX.length; row++) for (int col = 0; col < arrayX[0].length; col++) temp[arrayX.length - row -1][col] = arrayX[row][col]; return temp; } public static void print2DArray(int[][] arrayX){ for(int[] s:arrayX){ for(int sp: s) System.out.print(sp + " "); System.out.println(); } } public static void main(String[] args) { int[][] speed = { {99, 42, 74, 83, 100}, {90, 91, 72, 88, 95},{88, 61, 74, 89, 96}, {61, 89, 82, 98, 93}, {93, 73, 75, 78, 99},{50, 65, 92, 87, 94}, {43, 98, 78, 56, 99} }; int[][] vReflect = verticalReflect(speed); print2DArray(speed); print2DArray(vReflect); } } C. Try: Create a function that rotates the elements of a 1-D array by one position, moving the initial element to the end of the array, as shown at right.

    7.5 How to create a function to return the average values of an array?

    Discussion 
    A. Introduction The output of a function is the "returned" value. When defining the function, we have to specify the type of values returned. A function can either return a single value or an array. B. What does a function return? The return type of a method indicates the type of value that the method sends back to the calling location A method that does not return a value has a void return type. The return statement specifies the value that will be returned. For example, C. Try: create a function to return the average values of an array

    7.4 What happens when passing arrays to a function? What is a reference?

    Discussion 
    A. Introduction A function is essentially similar to a machine that turns input into output. So getting input is important. Parameters of a function are inputs. How are parameters passed to a function? B. Watch ( PPT ) C. Try: Create a function to return the maximum value of an int array
