Goals for this problem set:
Random
objects to produce random numbersRandom
methods
To use these methods, you need a variable of type Random
in
scope:
Random randy = new Random();
int aRandomNumber = randy.nextInt(10); // 09
Method name  Returns... 

nextInt()

a random integer 
nextInt(max)

a random integer between 0 (inclusive) and max (exclusive) 
nextDouble()

a random real number between 0.0 and 1.0 
nextBoolean()

a random boolean value: true
or false

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: 
rand.nextInt(5)
+
1

a random integer from 0 to 3 inclusive: 
rand.nextInt(4)

a random integer from 5 to 10 inclusive: 
rand.nextInt(6)
+
5

a random integer from 4 to 4 inclusive: 
rand.nextInt(9)

4

a random even integer from 16 to 28 inclusive: (Hint: To get only even numbers, scale up.) 
rand.nextInt(7)
*
2
+
16

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
execution:
guess = 43 guess = 47 guess = 45 guess = 27 guess = 49 total guesses = 5
