Given two numbers Min and Max, the task is to generate a random integer within this specific range in Java.
Examples:
Input: Min = 1, Max = 100 Output: 89 Input: Min = 100, Max = 899 Output: 514
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
// Java program to generate a random integer// within this specific range  import java.util.concurrent.ThreadLocalRandom;  class GFG {      public static int getRandomValue(int Min, int Max)    {          // Get and return the random integer        // within Min and Max        return ThreadLocalRandom            .current()            .nextInt(Min, Max + 1);    }      // Driver code    public static void main(String[] args)    {          int Min = 1, Max = 100;          System.out.println("Random value between "                           + Min + " and " + Max + ": "                           + getRandomValue(Min, Max));    }} |
Output:
Random value between 1 and 100: 35
