Java String Exercises: Sort in ascending and descending order by length of the given array of strings
Java String: Exercise-104 with Solution
Write a Java program to sort in ascending and descending order by length of the given array of strings.
Sample Solution:
Java Code:
import java.util.Arrays;
public class Main {
private static String[] strs = {"Green", "White", "Black", "Pink", "Orange", "Blue", "Champagne", "Indigo", "Ivory"};
public enum sort_asc_dsc{
ASC, DESC
}
public static void main(String[] args) {
System.out.println("\nOriginal unsorted colors: " + Arrays.toString(strs));
sort_array_by_length(strs, sort_asc_dsc.DESC);
System.out.println("\nSorted color (descending order): " + Arrays.toString(strs));
sort_array_by_length(strs, sort_asc_dsc.ASC);
System.out.println("\nSorted color (ascending order): " + Arrays.toString(strs));
}
public static void sort_array_by_length(String[] strs, sort_asc_dsc direction) {
if (strs == null || direction == null || strs.length == 0) {
return;
}
if (direction.equals(sort_asc_dsc.ASC)) {
Arrays.sort(strs, (String str1, String str2)
-> Integer.compare(str1.length(), str2.length()));
} else if (direction.equals(sort_asc_dsc.DESC)) {
Arrays.sort(strs, (String str1, String str2)
-> (-1) * Integer.compare(str1.length(), str2.length()));
}
}
}
Sample Output:
Original unsorted colors: [Green, White, Black, Pink, Orange, Blue, Champagne, Indigo, Ivory] Sorted color (descending order): [Champagne, Orange, Indigo, Green, White, Black, Ivory, Pink, Blue] Sorted color (ascending order): [Pink, Blue, Green, White, Black, Ivory, Orange, Indigo, Champagne]

How to sort an ArrayList?
Collections.sort(testList); Collections.reverse(testList);
That will do what you want. Remember to import Collections though!
