Goals for this problem set:
Randomobjects to produce random numbers
To use these methods, you need a variable of type
Random randy = new Random(); int aRandomNumber = randy.nextInt(10); // 0-9
||a random integer|
||a random integer between 0 (inclusive) and max (exclusive)|
||a random real number between 0.0 and 1.0|
Fill in the boxes to produce expressions that will generate random numbers in the provided ranges.
Assume that the following
Random variable has been declared:
Random rand = new Random();
|Example: a random integer from 1 to 5 inclusive:||
|a random integer from 0 to 3 inclusive:||
|a random integer from 5 to 10 inclusive:||
|a random integer from -4 to 4 inclusive:||
|a random even integer from 16 to 28 inclusive:
(Hint: To get only even numbers, scale up.)
Write a method named
makeGuesses that will output random
numbers between 1 and 50 inclusive until it outputs one of at least 48.
Output each guess and the total number of guesses made. Below is a sample
guess = 43 guess = 47 guess = 45 guess = 27 guess = 49 total guesses = 5
