Sample Output

This is what i manage to do now:
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();
words.add(word);
}

}
}
I tried to use the word.length(), but it gave me that it can;t find the symbol

Answer 1

Why not try it after gone to home..? I think that all code is given in question itself. If you not understand anything then you can ask .. or about any silly try or mistake,still post it undoubtedly..

I meant only saying 'without try you can't understand it' or "giving code will not help you..

ShadowRise it's up to you..
Anyways : you can code like these 2 ways:
In while:

while(words.size()<5){
String word = scanner.nextLine();
words.add(word);
if(word.length()>=5)
System.out.println(word);
}

Or in separate loop like:

for(String s: words)
if(s.length()>4)
System.out.println(s);

both works same.

Answer 2

Where you using word.length() ?
Upto now It's correct. But it is incomplete. just Add code for printing words which have length more than 4.
hope it helps..

Answer 3

Thank you, my problem was that i was printing out words instead of word, that;s my fault, sorry

Answer 4

@ShadowRice Oh. you found it. Task completed ..
You're welcome..

Answer 5

i don't know where to put it, in the while? i tried outside, but it won;t find my word.

Answer 6

You can put in while or also outside in other loop. Can you post that your try..?

Answer 7

I'm not home, can you solve it for me please?

Answer 8

you are declare word variable inside while so outside word doesn't exist

Answer 9

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

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

for (int i = 0; i < 5; i++) {
int input = scanner.nextInt();
numbers.add(input);
}

int sum = 0;
for (int number : numbers) {
sum += number;
}

System.out.println(sum);
}
}
