Java 8 introduced lots of new APIs for parallel processing data sets and streams. One such API is Arrays.parallelSort(). It breaks the array into different sub-arrays and each sub-array is sorted with Arrays.sort() in different threads. Finally all sorted sub-arrays are merged to one array as result.
