Explanation / Answer

BubbleSort.java

import java.util.Arrays;

import java.util.Scanner;

public class BubbleSort {

public static void main(String args[]) {

Scanner scan = new Scanner(System.in);

System.out.println("Enter the array size: ");

int n = scan.nextInt();

int[] someNums = new int[n];

System.out.println("Enter "+n+" numbers:");

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

someNums[i] = scan.nextInt();

}

int temp;

//Make another for loop, that goes through for each element

for(int j=0; j < n; j++){

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

System.out.println("Element at index "+ i + " is " + someNums[i]);

if(someNums[i] > someNums[i + 1]) {

temp = someNums[i];

someNums[i] = someNums[i + 1];

someNums[i + 1] = temp;

}

//System.out.println("Element at index "+ i + " is " + someNums[i]);

}

}

System.out.println(Arrays.toString(someNums));

}

}

Output:
