Errors On Compiling But Not Showing In Eclipse?

I am watching BrandonioProductions on youtube. His videos are pretty good, but he doesn't seem to get errors where I get them. Here is an example.

public class compareUnequal {
public static void main(String[] args){
compareTwo();
}
public static void compareTwo(){
String x = "david";
String y = "Notdavid";
if (!x.equals(y)){
System.out.println("Not equal");
}
}
}

It runs ok, but asked me to proceed when there is an error, but I can`t figure out where the error is!
