Practice Makes Perfect java practice

Question

I keep getting the “Cannot find symbol” error. Any and all assistance in figuring out what’s missing or wrong with my code is appreciated. Thanks!

Code will be in the next comment.

Answer 1

import java.util.LinkedList;
import java.util.Scanner;

public class Main {
public static void main(String[ ] args) {
Scanner scanner = new Scanner(System.in);

LinkedList<String> words = new LinkedList<String>();

while(words.size()<5){
String word = scanner.nextLine();
//add the word to LinkedList
words.add(word);}

//your code goes here
for(String s:words)
if(s.length()==4) System.out.println(s);
}
}

Answer 2

The program you are given declares LinkedList "words".
Write a program to take words as input and add them to LinkedList untill its size isn't equal to 5, then output only those words whose length is more than 4 characters.

import java.util.LinkedList;
import java.util.Scanner;

public class Main {
public static void main(String[ ] args) {
Scanner scanner = new Scanner(System.in);

LinkedList<String> words = new LinkedList<String>();

while(words.size()<5){
String word = scanner.nextLine();
//add the word to LinkedList
words.add(word);}

//your code goes here
if(words.length(word)>4){
System.out.println(word);}
}
}

Answer 3

word is not defined in the scope. It's a local variable in the while block

the length method is not defined in LinkedList class

Answer 4

I thought it might have something to do with the for loop but didn’t get the code right earlier. It’s good now. Thanks for the assist, Ciro! Have a good day!
