Pictorial Presentation:

Java: Generate random integers in a specific range

Sample Solution:

Java Code:

import java.util.Scanner;
public class Example3  {

      public static void main( String args[] ){ 
	    Scanner sc = new Scanner( System.in ); 
        System.out.print("Input the starting number of the range: "); 
        int rsnum = sc.nextInt(); 
        System.out.print("Input the ending number of the range: "); 
        int renum = sc.nextInt(); 
	    int random_num = rsnum + (int)(Math.random() * ((renum - rsnum) + 1));
	    System.out.println(random_num);
     }  
}

Sample Output:

Input the starting number of the range: 5                                                                     
Input the ending number of the range: 25
