Java Collection, LinkedList Exercises: Exercise-14 with Solution

Write a Java program to remove all the elements from a linked list.

Sample Solution:-

Java Code:

import java.util.*;
  public class Exercise14 {
  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("The Original linked list: " + l_list);

  // Removing all the elements from the linked list
    System.out.println("The New linked list: " + l_list);

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.
