Question

Need // descriptions for each line of code that is relevant (Example, a description of "arr[i]=r.nextInt(100)+1;".Will give positive rate

import java.util.Random;

public class TestApp {
public static void main(String[] args) {
   int arr[]=new int[11];
   Random r = new Random();

//Random function for generation of random numbers
   for(int i=0;i<arr.length;i++)

//
       arr[i]=r.nextInt(100)+1;
   printArray(arr);
   System.out.println();
   bubbleSort(arr);
   printArray(arr);
   System.out.println();
   System.out.println("Median : "+(arr[arr.length/2]));
}
private static void printArray(int[] aArray) {
   for (int i = 0; i < aArray.length; i++)
       System.out.print(aArray[i] + " ");
}
public static void bubbleSort(int[] list)

{

int temp;

for (int i = list.length - 1; i > 0; i--)

{

for (int j = 0; j < i; j++)

{

if (list[j] > list[j + 1])

{

temp = list[j];

list[j] = list[j + 1];

list[j + 1] = temp;

}

}

}

}

Following is the answer:

import java.util.Random;

public class TestApp {
    public static void main(String[] args) {
        //Initialize array with size of 11
        int arr[]=new int[11];

        //Creates a random object
        Random r = new Random();

        //Random function for generation of random numbers
        for(int i=0;i<arr.length;i++)
            //assign random number to array
            //generates random number using formula r.nextInt((max - min) + 1) + min
            //this generates random numbers between 1(inclusive) to 100(exclusive)
            arr[i]=r.nextInt(100)+1;

        //calls print array function and pass the array so printArray function prints the array
        printArray(arr);

        //This line is for next line prints in newline
        System.out.println();

        //calls the bubble sort function to sort an array
        bubbleSort(arr);

        //again prints the array after sorting
        printArray(arr);

        //This line is for next line prints in newline
        System.out.println();

        //prints the median of the sorted array using array[length/2]
        System.out.println("Median : "+(arr[arr.length/2]));
    }

    //print array function to print the array
    private static void printArray(int[] aArray) {
        //lopp the array
        for (int i = 0; i < aArray.length; i++)
            //print each element of the array with the space after each element
            System.out.print(aArray[i] + " ");
    }
    
    //sorting function to sort the array
    public static void bubbleSort(int[] list)
    {
        //initialize the temp variable
        int temp;

        //loop through length -1 to 0 and decrement the counter variable
        for (int i = list.length - 1; i > 0; i--)
        {
            //loop through 0 to i and increment counter variable
            for (int j = 0; j < i; j++)
            {
                //compare if arr[j] > arr[j+1] if true then swipes the element using temp variable
                if (list[j] > list[j + 1])
                {
                    //if condition is true them arr[j] is assigned to temp 
                    temp = list[j];
                    //arr[j] is changed to arr[j+1]
                    list[j] = list[j + 1];
                    //temp is assigned to arr[j+1], so elements are swiped
                    list[j + 1] = temp;
                }
            }
        }
    }
}
