Random integers

The book shows examples of how to use the Math.random method to generate random doubles between 0.0 and 1.0. By scaling and shifting these values, you can generate random values in a given range. For example, Math.random() * 100.0 + 10.0 yields a double between 10 and 110.

1.

Write a method called randInt that takes two arguments, low and high, and that returns a random integer between low and high.

2.

Write a method called randIntArray that is similar to randomArray on page 115, except it should take two additional arguments, low and high, and it should return an array of integers in the range from low to high.

3.

Write a method called prIntArray that takes an array of integers and prints them. Use it to debug randIntArray.
