How do you select a random number from 1 to 10 in Java?

How do you generate a random number between ranges in Java?

Approach:

Get the Min and Max which are the specified range.
Call the nextInt() method of ThreadLocalRandom class (java.util.concurrent.ThreadLocalRandom) and specify the Min and Max value as the parameter as ThreadLocalRandom.current().nextInt(min, max + 1);
Return the received random value.

How do you generate a random number?

There are two main methods that a computer generates a random number: true random number generators (TRNGs) and pseudo-random number generators (PRNGs). The former uses some phenomenon outside the computer for its number generation, whereas the latter relies on pre-set algorithms to emulate randomness².
