Question

Purpose: The JAVA application will allow the student to;

I.

demonstrate the declaration of an array;

II.

demonstrate the initialization of the array;

III

demonstrate the printing of the elements of the array.

Create a new file called "Array5A”

.

1.

Prepare a document box (tell me that task(s) the application is

to accomplish, how it will accomplish the tasks, the author of

the application, the date of completion, and any additional

notes.)

2.

Write a Java statement to create your header.

3.

Write a Java statement to create your "main" header.

4.

Create an array of type "double" to contain 4 elements. Then

name your array "salary".

5.

Write a series of Java statements of to initialize the 4 elements

of the "salary" array with the following

values:

5.25 6.55 10.25 16.85

(Note: initialize each element of the array individually, NO

LOOPS should be used or points will be deducted.)

6.

Output should be:

"Salaries one by one are: "

Write a series of print statements to print out the values

contained in the 4 "salary" array elements.

(Note: print each element of the array individually, no

loops)

Use your resources, examples from the PPT!

Required Elements:

1. IPO chart (Defining Diagram)
2. Solution Algorithm
3. Code
4. Run and Debug the code
5. Document (comments)

Answer 1

Part I:

====

public class Array5A {
    public static void main(String[] args){
        int integerAyyay[];
        //int [] array;  -> this is also valid declaration

        //Initialization of array
        integerAyyay = new int[]{1,2,3,4,5};
        System.out.println("First element in array: "+integerAyyay[0]);
        System.out.println("Second element in array: "+integerAyyay[1]);
        System.out.println("Third element in array: "+integerAyyay[2]);


    }
}

Part 2:

=====

/**
 *This is document box, where you can write details about your program
 * like author, task, date and purpose
 *
 * This is first question answer in part 2
 */

//Write a Java statement to create your header. 2nd question
//JAva never had a concept of header. Please comment about this so that I can edit the answer
public class ArrayDemo {
    public static void main(String[] args){ //Main header. Third question answer
            double[] salary = new double[4]; // 4th question
            //Fifth
            salary[0]=5.25;
            salary[1]=6.55;
            salary[2]=10.25;
            salary[3]=16.85;

            System.out.println("Salaries one by one are: "); //6th question
            System.out.println(salary[0]);
            System.out.println(salary[1]);
            System.out.println(salary[2]);
            System.out.println(salary[3]);

    }

}
