Array sort----arrays.sort () method

Arrays.sort () is able to sort the array.

Default from small to large, if you want to adjust the order, you need to implement the comparator interface and call

Arrays.sort () can sort data types such as int[], double[], char[], long[], byte[], short[], as illustrated by the most common example of int[] arrays.

Arrays.sort (int[] values)

This way you can sort the array elements of basic types such as int[], double[], long[], by default from small to large

Arrays.sort (int[] A, int fromIndex, int toindex)

This function sorts the data from FromIndex to toIndex-1 for the base type array, as shown below.

Arrays.sort (object[] oj1,new sortcomparator ())

This way you can sort an array of reference types by using the Compare method declared in comparator

Arrays.sort (object[] oj1, int fromIndex, int toindex, new sortcomparator)
