import java.util.Scanner;

public class Chpt7_Project {

   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;
   }
   }
   }
   }

   public static void main(String[] args) {
       Scanner in = new Scanner (System.in);
       int[] array = new int[11];
       System.out.print("Enter 11 integers: ");
       for (int i = 0; i < array.length; ++i) {
           array[i] = in.nextInt();
                  
       }
       bubbleSort(array);
       System.out.println("Array before sorting: "+array.toString());
       System.out.println("Median is " + array[5]+ " and it is at position 5.");

Java, how can I display the array before sorting and the array after sorting?

Answer 1

import java.util.Scanner;
import java.util.Arrays; // need to import util.Arrays

public class Chpt7_Project {

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;
}
}
}
}

public static void main(String[] args) {
Scanner in = new Scanner (System.in);
int[] array = new int[11];
System.out.print("Enter 11 integers: ");
for (int i = 0; i < array.length; ++i) {
array[i] = in.nextInt();
  
}
// it must be Arrays.toString(name of array)
System.out.println("Array before sorting: "+ Arrays.toString(array));
bubbleSort(array);
//to print median
System.out.println("Median is " + array[5]+ " and it is at position 5.");
// array contents after sorting
System.out.println("Array after sorting: "+ Arrays.toString(array));
}
}
obtained output:

Array before sorting: [9, 8, 6, 7, 5, 2, 3, 4, 1, 12, 11]
Median is 6 and it is at position 5.
Array after sorting: [1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12]
