This is my code

String [] name = { };

System.out.println (Arrays.toString(name) + " => Nobody likes this post");

}

public static void onelikes(){
String[] name = {"Ikko"};

System.out.println (Arrays.toString(name) + " => " + name[0] + " likes this post");
}

public static void threelikes(){
String[] name = {"Danielle", "Liza", "Sue"};

System.out.println (Arrays.toString(name) + " => " + name[0] + ", " + name[1] + " and " + name[2] + " likes this post");
}

public static void fourlikes(){
String[] name = {"Ken", "James", "John", "Seb"};

System.out.println(Arrays.toString(name) + " =>" + name[0] + ", " + name[1] + " and 2 others like this post");
}

public static void main(String x[])
{
empty();
onelikes();

It says it's wrong idk what's wrong but it runs. This is how it said:

LikedItSampleTest.java:7: error: cannot find symbol LikedIt likedIt = new LikedIt(); ^ symbol: class LikedIt location: class LikedItSampleTest LikedItSampleTest.java:7: error: cannot find symbol LikedIt likedIt = new LikedIt(); ^ symbol: class LikedIt location: class LikedItSampleTest LikedItSampleTest.java:13: error: cannot find symbol LikedIt likedIt = new LikedIt(); ^ symbol: class LikedIt location: class LikedItSampleTest LikedItSampleTest.java:13: error: cannot find symbol LikedIt likedIt = new LikedIt(); ^ symbol: class LikedIt location: class LikedItSampleTest LikedItSampleTest.java:19: error: cannot find symbol LikedIt likedIt = new LikedIt(); ^ symbol: class LikedIt location: class LikedItSampleTest LikedItSampleTest.java:19: error: cannot find symbol LikedIt likedIt = new LikedIt(); ^ symbol: class LikedIt location: class LikedItSampleTest 6 errors Error: Could not find or load main class MainTest Caused by: java.lang.ClassNotFou

Answer 7

I try the other one but still it's wrong

import java.util.Arrays;
public class Mod_12
{
public static void main(String x[])
{
String [] one = { };
String[] two = {"Ikko"};
String[] three = {"Danielle", "Liza", "Sue"};
String[] four = {"Ken", "James", "John", "Seb"};

System.out.println (Arrays.toString(one) + " => Nobody likes this post");
System.out.println (Arrays.toString(two) + " => " + two[0] + " likes this post");

System.out.println (Arrays.toString(three) + " => " + three[0] + ", " + three[1] + " and " + three[2] + " likes this post");

System.out.println(Arrays.toString(four) + " =>" + four[0] + ", " + four[1] + " and 2 others like this post");

}}

There's no input in instructions. I don't know how to put this Assertion in java it's new to me. It's about Assertion and arrays with in each 3 public voids
