    Post Having problems with basics

    Hello, I started learning Java and I ran in to some troubles with the basics while I was trying to figure out some arrays.
    I wrote 2 for loops and I tried to make them identical as possible but the error on last line in the second loop says "n cannot be resolved to a variable"
    what seems to be the problem?

    public class apps {
    public static void main(String[] args) {

    String[] words = new String[3];
    words[0] = "Hello ";
    words[1] = "to ";
    words[2] = "you ";

    for(int i=0; i<3; i++)
    System.out.print(words[i]);


    String[] bestSinger = new String[4];
    bestSinger[0] = "Billie ";
    bestSinger[1] = "Eilish ";
    bestSinger[2] = "kicks ";
    bestSinger[3] = "ass! ";


    for(int n=0; n<4; n++);
    System.out.print(bestSinger[n]);


    }
    }

    The print statement is outside of the for loop, so its control variable is not defined.
    The for statement (and most statements) ends with the ; that is after the )
    Remove the ; to include the print statement inside of the for loop
    It is better to Wrap the contents of the for loop with {}s
    If you don't understand my answer, don't ignore it, ask a question.
