testJavadoc(week01.JUnitJavadocValidation)
- message:

Could you please create that class and give me an explanation on why I got these errors.
bellow is the package for testing
Thank you.

Explanation / Answer
You need to Create HelloWorld.java
I have Created HelloWorld.java and added display() method. Added JavaDoc.
Use this class and let me know if it works fine for you
IMPORTANT
Change below line as well
boolean helloWorldTest = executeTest(HelloWorld.class);
///****************************HelloWorld**************/
//
package week01;
/**
* File: HelloWorld.java
* @author Dina
*/
public class HelloWorld
{
/**
* Default constructor
*/
public HelloWorld()
{
}
/**
* Display method just
*returns the String "Hello World from"
*/
public String display() {
return "Hello World from";
}
@Test
public void runTest()
{
boolean result = true;
HelloWorld hello = new HelloWorld();
String msg = hello.display();
// trace("Results from executing display() method: ");
// trace(" ");
if(msg.length() > 1 && msg.contains("Hello World from"))
{
result = true;
}
else
{
result = false;
//trace("Message doesn't match requirements - expected Hello World from ");
}
assertTrue("Message doesn't match requirements - expected Hello World from ", result);
}
static private void trace(String msg)
{
System.out.println(msg);
}
}
