unrechable statement

So im trying to solve this exercise and I keep getting the eror that my "returnd fieldName" is unrechable.

TeacherAssistant.java 
public class TeacherAssistant {

  public static String validatedFieldName(String fieldName) {
    // These things should be verified:
    // 1.  Member fields must start with an 'm'
    // 2.  The second letter in the field name must be uppercased to ensure camel-casing
    // NOTE:  To check if something is not equal use the != symbol. eg: 3 != 4
    if (fieldName.charAt(0) != 'm' && !Character.isUpperCase(fieldName.charAt(1)));{
    } throw new IllegalArgumentException (" Wrong style of the member");
    return fieldName;
  }

}

Hey Martis,

Just a few small things to fix in this, the first thing is that your conditional statements that you're looking for are spot on and correct, but instead we want the or operand || so that if one of these conditions are wrong the illegal Argument Exception is thrown.

Also, after your if statement you have a semicolon, this is what is causing Java to get hung-up. Remove the semicolon, and put the IllegalArgument Exception in your if block, so that it's thrown if any of the conditions are not met.

Other than that, this looks good.
