1. What This Assignment Is About: Classes (methods and attributes) Objects Arrays of Primitive Values Arrays of Objects . .Recursion for and if Statements .Selection Sort 2. 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 Os in the even positions c) Create a static method printArray that receives as a parameter an array of integers.
