----------------------------------------------------------------
[~geertjan] it actually still doesn't work when trying with other projects so
there's still an issue with Netbeans. I have this simple vowel counter class
and when I run the project in Netbeans it doesn't give me the initial output
"Enter a word:" I have to type something first and then it prints everything in
the end so it's skipping an output. Very weird. In Eclipse the project works
perfectly.
{code:java}
import java.util.Scanner;
public class Vowels {
public static void main(String[] args) {
int count = 0;
Scanner scan = new Scanner(System.in);
System.out.print("Enter a word: ");
String word = scan.nextLine();
for (char c : word.toLowerCase().toCharArray()) {
if (isVowel(c)) {
count++;
}
}
System.out.println("Total Vowels : " + count);
scan.close();
}
private static boolean isVowel(char c) {
return (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u' || c
== 'y');
}
}
{code}

> Key: NETBEANS-4099
> URL: https://issues.apache.org/jira/browse/NETBEANS-4099
> Project: NetBeans
> Issue Type: Bug
> Affects Versions: 11.0, 11.2, 11.3
> Environment: I've tried on both Macbook Pro with macOS Catalina and
> Windows 10 and get the same issue even though the Netbeans IDE and Java SE
> Development Kit are compatible. When I try the code on Eclipse, it works
> perfect which shows that there is not an issue with the code, the issue is
> with Netbeans. Must be some configuration not allowing input from the user in
> a console.

> When using the scanner class, Netbeans 11.0, 11.2 and 11.3 still does not
> allow user input in the console like the scanner class should normally do.
> Here is a link to a similar issue and it has not been resolved
> https://issues.apache.org/jira/browse/NETBEANS-3073
> I get the following error.
