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));     } } |
Random value between 1 and 100: 35
