int[] intArray =newint[]{1,34,5,-9}; Arrays.sort(intArray); System.out.println(Arrays.toString(intArray)); 2.一维数组逆序 Java的Arrays.sort()仅支持对引用数据类型进行自定义排序,如果是基本数据类型(如int类型),将无法使用Comparator进行自定义排序。 可以先正序再reverse int[] nums =newint[]{...
https://www.geeksforgeeks.org/arrays-sort-in-java-with-examples/Array class is a class containing static methods that are used with arrays in order to search, sort, compare, insert elements, or return a string representation of an array. So let us specify the functions first and later ...
Calling reverse() on the array reverses the order to 5, 4, 3, 2, 1. The sort() method puts the items in ascending order. The sort() method calls the String() casting function on every item and then compares the strings to determine the correct order. ...
Sorting an Array Thesort()method sorts an array alphabetically: Example constfruits = ["Banana","Orange","Apple","Mango"]; fruits.sort(); Try it Yourself » Reversing an Array Thereverse()method reverses the elements in an array:
