Work in pairs on this lab.
Write a program that has an array of articles, an array of adjectives,
an array of nouns, and an array of verbs and constructs random sentences
based on the scheme
article + adjective + noun + verb
For instance, the program may randomly select an article "My", an adjective "old",
a noun "dog", and a verb "is walking", to make a sentence "My old dog is walking".
Make sure to have at a different number of elements in different arrays
(for instance, you would probably have fewer articles than nouns).
Write methods as needed; avoid code repetition (if you repeat roughly
the same code, make it into a method).
Write a program that simulates 500 rolls of two six-sided dice. Create an array of integers to count how many times each sum occurs. For instance, if you get 3 on the first die and 5 on the second one, then the result is 8, and the array element that counts the number of 8s needs to be incremented. At the end print out how many times each sum occurred. In comments write your conclusions about probabilities of different sums.
Write and test a method int) and returns the number of negative elements in the array.
Imagine you have just started working in a software development
company, and your boss asks
you to take a look at some code written by your predecessor at the
company. Your boss says that the company software occasionally
outputs unexpected results, and the method isOdd may be
to blame. Unfortunately, the actual data ran by the client requires
security clearance which you don't yet have. Because of that you
don't know what data causes problems and whether it is related
to the method isOdd. You are asked to test
the method and report back on whether the method is correct,
and if it's not then to explain what is wrong with it and fix it.
Make sure to fix it in a good programming style (if a fix is indeed
needed). Make sure to include all your test data in your report.
Below is the code:
public class IsVeryOdd {
public static void main(String [] args) {
// your test code goes here
}
/** The method takes an integer n and returns true if
n is odd and false otherwise
**/
public static boolean isOdd(int n) {
return ( (n % 2) == 1);
}
}
