BubbleSort.java

//WHAT IS BUBBLE SORT:
//Bubble Sort is one of the simplest sorting techniques in Java to sort the array elements. 
//The swapping of elements continues until the array is sorted and no more swapping is required. 
//We can also sort the elements in the descending order in which the smallest element goes at the end of the array in each iteration.
//THIS EXPLAINATION IS PROVIDED TO HELP BEGGINNER'S UNDERSTAND THE CODE
