Question 1 (similar to prelim question -- you should be able to quickly write down short methods like this without too much trouble by now):
Write a function numTween that takes a non-empty integer array b and two integers x and y as parameters and returns the number of elements in the array that are both greater than or equal to x and less than or equal to y. For example if b is
3 7 9 2 1 13 11 4 6
and x is 5 and y is 10, then the function should return 3, because there are 3 elements in b that are >= 5 and <= 10, namely, 7, 9 and 6.

public int numTween(int[] b, int x, int y) {

}

Question 2: Think about Matlab arrays and Java arrays. Yesterday in class we talked about a few differences between them. Give an example of one such difference that was mentioned in class. Hint: think indices.
