Question

Please write a JAVA program according to following requirement. Thanks

Part 2 -Arrays We can use the Math.random method to generate random integers. For example, Math.random () generates a random integer greater than or equal to 0 and less than 1. The expression Math. random) 6generates random numbers between 0 and 5, simulating the throw of a die. In this lab assignment, you will use an array to test whether the random generator is fair; that is, whether each possible value is generated approximately the same number of times. Write a program Lab10. Your program should ask the user How many random numbers should be generated? What is the number of values for each random draw? (e.g., 6) Make an array with one element for each possible outcome (i.e., the size of the array should be equal to the number of values for each random draw). Set each element in the array to 0. Then keep calling the random number generator. If it returns a value v, then increment the counter belonging to v After all numbers have been generated., print the counters array. Also, prints the difference between the max and min count. Here is a typical program run: How many random numbers do you want to generate? 100 What is the number of values for each random draw? 0 151 1 161 2 183 3 152 5 176 The max difference = 32 How many random numbers do you want to generate? What is the number of values for each random draw? 0 6 1 0 2 4 The max difference = 6 In order to get credit for the lab Your instructor or TA must check your work by watching your program run and looking at your code. 1. 2. You must turn in this sheet. 3. Submit your code to Canvas

int n= in.nextInt();
  
int i,j,k;
int count[]= new int[n];
  
for(i=0;i<n;i++)count[i]=0;
for(i=0;i<number_of_numbers;i++)
{
double ran= Math.random()*n;
//int temp= (int)Math.round(ran);
//int temp= ran.intValue();
int temp= (int)ran;
count[temp]++;
}
  
int mini=number_of_numbers+1,maxi=-1;
System.out.println("");
for(i=0;i<n;i++)
{
if(maxi<count[i])
maxi=count[i];
if(mini>count[i])
mini=count[i];
System.out.println(i+" "+count[i]);
}
  
System.out.println("The max difference is "+(maxi-mini));
}

}
