Java Collection, LinkedList Exercises: Exercise-16 with Solution

Write a Java program to shuffle the elements in a linked list.

Sample Solution:-

Java Code:

import java.util.*;

public class Exercise16 {
 public static void main(String[] args) {
  // create an empty linked list
  LinkedList <String> l_list = new LinkedList <String> ();
  // use add() method to add values in the linked list
  // print the list
  System.out.println("Linked list before shuffling:\n" + l_list);  
  System.out.println("Linked list after shuffling:\n" + l_list); 

Sample Output:

Linked list before shuffling:                                          
[Red, Green, Black, Pink, orange]                                      
Linked list after shuffling:                                           
[orange, Pink, Red, Black, Green]

Java: Tips of the Day

Choice between Float and Double:

Data type Bytes used Significant figures (decimal)
Float 4 7
Double 8 15

Double is often preferred over float in software where precision is important because of the following reasons:
Most processors take nearly the same amount of processing time to perform operations on Float and Double. Double offers far more precision in the same amount of computation time.
