Bubble sorting of Java data structures and algorithms (power node Java College)

Bubble sorting (bubble sort) is a simple sorting algorithm. It repeatedly visits the sequence to be sorted, compares two elements at a time, and exchanges them if their order is wrong. The work of visiting the sequence is repeated until there is no need to exchange, that is, the sequence has been sorted. The name of this algorithm is because the smaller elements will pass through the intersection Slowly "float" to the top of the sequence.

The bubble sorting algorithm operates as follows:

1. Compare adjacent elements. If the first one is bigger than the second, exchange them.

2. Do the same work for each pair of adjacent elements, from the first pair at the beginning to the last pair at the end. At this point, the last element should be the largest number.

3. Repeat the above steps for all elements except the last one.

4. Continue to repeat the above steps for fewer and fewer elements each time until there is no pair of numbers to compare.
