I'm using an online Java compiler for my project, and I'm encountering unexpected behavior in the execution of my code. Here's a simplified snippet:

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<String> fruits = new ArrayList<>();
        fruits.add("Apple");
        fruits.add("Banana");
        fruits.add("Orange");

        for (String fruit : fruits) {
            System.out.println(fruit.length());
        }
    }
}

Despite the seemingly straightforward code, I'm not getting the expected output. What could be causing this issue with the online Java compiler, and how can I rectify it to ensure proper code execution and output?

.. try using different Java online compiler.. ?

 

I tried this:

https://www.programiz.com/java-programming/online-compiler/

And it showed:

java -cp /tmp/gCdTYn4aQ5 Main
5
66

But this 66 is simply a lack of EOL....

After changing the code to:

System.out.println(""+fruit.length());

all is fine..

java -cp /tmp/gCdTYn4aQ5 Main
5
6
6

 

ps. Report the problem to the developers who created the online compiler, along with a code snippet, and it will be fixed.
