/**
 * Validate the "initial fish count" {@link EditText}. The text is already provided as a parameter.
 *
 * If the text is valid the "initial shark count" {@link EditText} is validated as well to eventually remove an
 * error that previously existed (e.g., number of initial fish was reduced so that the number of shark are now valid).
 *
 * Note that the "initial shark count" {@link EditText} is not validated if the text is invalid to not add
 * an error message to the "initial shark count" {@link EditText} if this text value is invalid.
 *
 * @param s         text of the "initial fish count" {@link EditText}
 * @param worldSize size of the world//from w  w w.j  a v  a 2 s  . co  m
