JAVA ARRAY SORT HOW TO

Here is a third option to merge to arrays: System.arraycopy.

This function associates an index with a result. This method will set all array element according to the given function. In Arrays class there are several overloaded sort () methods are available. Int resultArray = new int įor (int i = 0 i (i < anArray.length ? anArray : anotherArray)) Just import the Arrays class and use the Arrays.sort () in Java which gives the best performance in most cases compared to other sorting algorithms.

Let's see how this all work through some examples: int anArray = new int The algorithms behind the sort method are quick sort and merge sort for primitive and other arrays, respectively. We can invoke it directly using the class name. It is a static method that parses an array as a parameter and does not return anything. It uses Dual-Pivot Quicksort algorithm for sorting. In addition, it's possible to sort only a specific portion of an array (passing start and end indices to the method). In Java, Arrays is the class defined in the java.util package that provides sort () method to sort an array in ascending order.

Generic arrays: which are sorted according to a given Comparator.

Object arrays (those Object must implement the Comparable interface): which are sorted according to the natural order (relying on the compareTo method from Comparable).

Primitive type arrays: which are sorted in ascending order.

The Arrays class provides us with the sort method. A bit like the stream method, sort has a lot of overloadings.

Let's now see how to sort an array, that is rearranging its elements in a certain order.
