Java Collection, LinkedList Exercises: Exercise-5 with Solution

Write a Java program to insert the specified element at the specified position in the linked list.

Sample Solution:-

Java Code:

import java.util.LinkedList;
public class Exercise5 {
	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("White");
		l_list.add("Pink");
		System.out.println("Original linked list: ");
		System.out.println("Let add the Yellow color after the Red Color: " + l_list);
		l_list.add(1, "Yellow");
		// print the list
		System.out.println("The linked list:" + l_list);
	}
}

Sample Output:

Original linked list:                                                  
Let add the Yellow color after the Red Color: [Red, Green, Black, White
, Pink]                                                                
The linked list:[Red, Yellow, Green, Black, White, Pink]

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.
