Question

package BubbleSort;
public class BubbleSort {
public static void main(String[] args) {
//create an int array we want to sort using bubble sort algorithm
int intArray[] = new int[]{5,90,35,45,150,3};
//print array before sorting using bubble sort algorithm
System.out.println("Array Before Bubble Sort");
for(int i=0; i < intArray.length; i++){
System.out.print(intArray[i] + " ");
}
//sort an array using bubble sort algorithm
bubbleSort(intArray);
System.out.println("");
//print array after sorting using bubble sort algorithm
System.out.println("Array After Bubble Sort");
for(int i=0; i < intArray.length; i++){
System.out.print(intArray[i] + " ");
}
}

private static void bubbleSort(int[] intArray) {
int n = intArray.length;
int temp = 0;
for(int i=0; i < n; i++){
for(int j=1; j < (n-i); j++){
if(intArray[j-1] > intArray[j]){
//swap the elements!
temp = intArray[j-1];
intArray[j-1] = intArray[j];
intArray[j] = temp;
}
}
}
}
}

**Programming Challenge 1:**

Create a Java program that collects numeric data from a user (10 values minimum), sorts that data using a bubble sort algorithm in ascending order, and then displays the resulting ordered set.

**Programming Challenge 2:**

Create a Java program that creates 25 random 4-digit numbers and adds them to an array. Once the array has been populated, then sort the array using a bubble sort algorithm.

**Please submit a screenshot of your program and output results to the Canvas assignment.**
