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
