Question

need help editing or rewriting java code, I have this program running that creates random numbers and finds min, max, median ect. from a group of numbers,array. I need to use a data class and a constructor to run the code instead of how I have it written right now. this is an example of what i'm being asked for.

This is my code:

import java.util.Random;

import java.util.Scanner;

public class RandomArray {

// method to find the minimum number in array

public static int minimum(int []a) {

int min=a[0];

for(int i=1;i<a.length;i++) {

if(a[i]<min)

min=a[i];

}

return min;

}

// method to find the maximum number in array

public static int maximum(int []a) {

int max=a[0];

for(int i=1;i<a.length;i++) {

if(a[i]>max)

max=a[i];

}

return max;

}

// method to calculate average

public static double average(int []a) {

double sum=0.0,avg;

for(int i=0;i<a.length;i++) {

sum=sum+a[i];

}

avg=(double)sum/a.length;

return avg;

}

// method to sort the array

public static void sort(int []a) {

for(int i=0;i<a.length-1;i++) {

for(int j=0;j<a.length-i-1;j++) {

if(a[j]>a[j+1]) {

int t=a[j];

a[j]=a[j+1];

a[j+1]=t;

}

}

for(int i1=0;i1<a.length;i1++) {

System.out.print(a[i1]+" ");

}

System.out.println();

}

}

// method to find median

public static int median(int []a) {

int n=a.length,m;

if(n%2==1) {

return a[(n/2)+1];

}else {

return a[((n/2)+((n/2)+1))/2];

}

}

public static void main(String[] args) {

// Scanner class object to get input from user

Scanner sc=new Scanner(System.in);

// Random class object to genarate random number

Random r=new Random();

int size;

while(true) {

System.out.print("Number of random numbers: ");

size=sc.nextInt(); // get size of array from user

if(size>=12 && size<=20)

break;

else

System.out.println("Size must be between 12 to 20...!!!");

}

// create the array

int arr[]=new int[size];

for(int i=0;i<size;i++) {

// generate random number between 10 to 99 and store it in array

arr[i]=r.nextInt(99-10)+10;

}

System.out.println("\nSample Data:");

for(int i=0;i<size;i++) {

System.out.print(arr[i]+" ");

}

System.out.println("\nMinimum= "+minimum(arr));

System.out.println("Maximum= "+maximum(arr));

System.out.println("Average= "+average(arr));

System.out.println();

sort(arr);

System.out.println("\nMedian= "+median(arr));

}

}
