How to set a specific min and max to random number

Question

I wanted to print a random number that starts with 30 and ends with 95. But it still prints 29 and lower. Here's my the code of formula that I used.

ran_num = (95 - 30 + 1) + 30;

Do you want to get a random number between 30 and 95 (each inclusively)? — deHaar, Jul 06 '20 at 10:54
Then use a `Random` or a `ThreadLocalRandom`, no need for custom calculations... — deHaar, Jul 06 '20 at 10:56
The code in the question does not generate any random numbers, since it's all fixed values. `ran_num` will always be assigned value `96`!! — Andreas, Jul 06 '20 at 11:17

You can have a random number between 30 and 95 by using a ThreadLocalRandom for example.

A code that prints 10 random numbers in that range could look like this:

for (int i = 0; i < 10; i++) {
    System.out.println(ThreadLocalRandom.current().nextInt(30, 96)); // upper border exclusive
}

If you want to store a random in a variable, write something like

int randomNumber = ThreadLocalRandom.current().nextInt(30, 96);

can I put that in a variable? – moonman Jul 06 '20 at 11:04
@moonman sure, you can store the result of that call in an `int`... – deHaar Jul 06 '20 at 11:04
thank you sir. this really help – moonman Jul 06 '20 at 11:11
