How do I sort LinkedList elements?
Category: java.util, viewed: 1426 time(s).
To sort the elements of LinkedList we can use the Collections.sort(List list) static methods. The default order of the sorting is a descending order.
package org.kodejava.example.util;
import java.util.LinkedList;
import java.util.Collections;
public class LinkedListSort {
public static void main(String[] args) {
LinkedList<String> grades = new LinkedList<String>();
grades.add("E");
grades.add("C");
grades.add("A");
grades.add("F");
grades.add("B");
grades.add("D");
System.out.println("Before sorting:");
System.out.println("===============");
for (String grade : grades) {
System.out.println("Grade = " + grade);
}
//
// Sort the elements of linked list based on its data
// natural order.
//
Collections.sort(grades);
System.out.println("After sorting:");
System.out.println("===============");
for (String grade : grades) {
System.out.println("Grade = " + grade);
}
}
}
The result of the program are:
Before sorting:
===============
Grade = E
Grade = C
Grade = A
Grade = F
Grade = B
Grade = D
After sorting:
===============
Grade = A
Grade = B
Grade = C
Grade = D
Grade = E
Grade = F
