Java implementation bubble sort and bidirectional bubble sort algorithm code example _java

Bubble Sort: is the two elements that are contiguous by index, and if greater than/less than (depending on whether ascending or descending order is required), replace, otherwise do not make changes this round down, compares the n-1 times, n equals the number of elements; n-2 , n-3 ... One to the last round, compared 1 times so the comparison is decremented: from n-1 to 1 The total number of comparisons is: 1+2+3+...+ (n-1), is calculated in a linear formula: (1+n-1)/2* (n-1) ==> n/2* (n-1)
