How do I generate random integers within a specific range in Java?

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
