Java Collection, LinkedList Exercises: Exercise-12 with Solution

Write a Java program to remove a specified element from a linked list.

Sample Solution:-

Java Code:

import java.util.*;

public class Exercise12 {
 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
  l_list.add("Red");
  l_list.add("Green");
  l_list.add("Black");
  l_list.add("Pink");
  l_list.add("orange");

  // print the list
  System.out.println("The Original linked list: " + l_list);

  // Remove the element in third position from the said linked list
  l_list.remove(2);
  System.out.println("The New linked list: " + l_list);
 }
}

Sample Output:

The Original linked list: [Red, Green, Black, Pink, orange]

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.
