Homework 1 Programming with Java:

What This Assignment Is About:

Classes (methods and attributes)

Objects

Arrays of Primitive Values

Arrays of Objects

Recursion

for and if Statements

Selection Sort

Use the following Guidelines:

Give identifiers semantic meaning and make them easy to read (examples numStudents, grossPay, etc).

User upper case for constants. Use title case (first letter is upper case) for classes. Use lower case with uppercase word separators for all other identifiers (variables, methods, objects).

Use tabs or spaces to indent code within blocks (code surrounded by braces). This includes classes, methods, and code associated with ifs, switches and loops. Be consistent with the number of spaces or tabs that you use to indent.

Use white space to make your program more readable.

For each file (class) in your assignment, provide a heading (in comments) which includes:

The assignment number.

Its author (your name).

A description of what this program is doing.

3. Part 1. Primitive Types, Searching, Recursion (35 points).

a) Create a class Homework (in a file Homework.java)

b) Create a static method initializeArray that receives as a parameter an array of integers. Use a for loop and an if statement to put 1s in the odd positions of the array and 0s in the even positions.

c) Create a static method printArray that receives as a parameter an array of integers. Use

a while statements to print all the elements in the array.

d) Create a static method arraySelectionSort that receives as a parameter an array of integers and order its element in ascending order. Implement Selection Sort algorithm. It should be Selection Sort, not Bubble Sort, not Quick Sort, etc. If you do not remember selection sort, this link could be useful: https://goo.gl/hrAdMo

e) Create a static recursive method that calculate and returns the factorial a number. The method receives the number (integer number) as parameter

f) Copy the following main method in your class,

public static void main (String [] arg) { int [] a = {3, 5, 6, 8, 12, 13, 16, 17, 18, 20}; int [] b = {18, 16, 19, 3 ,14, 6}; int [] c = {5, 2, 4, 3, 1};

// testing initializeArray printArray(a); // print: 3, 5, 6, 8, 12, 13, 16, 17, 18, 20 initializeArray(a); printArray(a); // print: 0, 1, 0, 1, 0, 1, 0, 1, 0, 1

// testing initializeArray printArray(b); // print: 18, 16, 19, 3 ,14, 6 arraySelectionSort (b); printArray(b); // print: 19, 18, 16, 14, 6, 3

// testing factorial System.out.println (factorial (5)); //print: 120

c[0] = factorial (c[0]); c[1] = factorial (c[2]); printArray(c); // print: 120, 24, 4, 3, 1

}
