Introductory Programming Exercises: Java

The rules for these exercises are:

• You are not required to submit them.
• You must commit them in version control (GitHub) when complete. It would be smart for you to commit every 15 minutes.
• You must implement and run them in IntelliJ/Java.

Exercises

Triangles

1. Easiest

   Print one asterisk to the console.

   Example:

   *
   

2. Draw a horizontal line

   Given a number n, print n asterisks on one line.

   Example when n=8:

   ********
   

3. Draw a vertical line

   Given a number n, print n lines, each with one asterisks.

   Example when n=3:

   *
   *
   *
   

4. Draw a right triangle

   Given a number n, print n lines, each with one more asterisk than the last (i.e. one on the first line, two on the second,etc.)

   Example when n=3:

   *
   **
   ***
   

Diamonds

5. Isosceles triangle

   Given a number n, print a centered triangle.

   Example for n=3:

     *
    ***
   *****
   

6. Diamond

   Given a number n, print a centered diamond.

   Example for n=3:

     *
    ***
   *****
    ***
     *
   

7. Diamond with name

   Given a number n, print a centered diamond with your name in place of the middle line.

   Example for n=3:

     *
    ***
   Bill
    ***
     *
   

FizzBuzz

FizzBuzz is a simple number game where you count, but say "Fizz" and/or "Buzz" instead of numbers adhering to certain rules.

Create a FizzBuzz() method that prints out the numbers 1 through 100. Instead of numbers divisible by three print "Fizz". Instead of numbers divisible by five print "Buzz". Instead of numbers divisible by three and five print "FizzBuzz".

Sample Output:

1
2
Fizz
4
Buzz
Fizz
7
8
Fizz
Buzz
11
Fizz
13
14
FizzBuzz

Prime Factors

Write a method generate(int n) that given an integer N will return a list of integers such that the numbers are the factors of N and are arranged in increasing numerical order.

For example, generate(1) should return an empty list and generate(30) should return the numbers: 2,3,5.
