Question

Create applications that use Math. random() to generate random numbers for each of the following situations: 3. a) Random51 100: Generate a random integer between 51 and 100. b) Random120 200: Generate a random integer between 120 and 200. c) Random40_50: Generate a random double between 40 and 50, inclusive.

Answer 1

a)

Code:

class ya{
   public static void main(String args[]){
       int a=99,b=52;
       int number=(int) (Math.random()*((b-a)+1))+a;
       System.out.println("Random integer between 51 and 100 is "+number);
   }
}

Output:

Random integer between 51 and 100 is 54

b)

Code:

class second{
   public static void main(String args[]){
       int a=121,b=199;
       int number=(int) (Math.random()*((b-a)+1))+a;
       System.out.println("Random integer between 121 and 200 is "+number);
   }
}

Output:

Random integer between 121 and 200 is 126

c)

Code:

class third{
   public static void main(String args[]){
       int a=40,b=50;
       int number=(int) (Math.random()*((b-a)+1))+a;
       System.out.println("Random integer between 40 and 50,inclusive is "+number);
   }
}

Output:

Random integer between 40 and 50, inclusive is 44,
