Why can't I throw an exception while using the ternary operator

Question

This doesn\'t compile and gives the following error : Illegal start of expression. Why?

public static AppConfig getInstance() {
        return mConf         


        

Answer 1

You may write an utility method

public class Util
{
  /** Always throws {@link RuntimeException} with the given message */
  public static  T throwException(String msg)
  {
      throw new RuntimeException(msg);
  }
}

And use it like this:

public static AppConfig getInstance() 
{
    return mConfig != null ? mConfig : Util. throwException("error");
}
