CSCI 1100 REVIEW

• Q: What is a method header and what is a method definition? A: The method header or declaration is the signature of a method and includes the visibility modifier, return type, method name, parameter list and throws clause for exceptions. For example:

  public int fibonacci(int n) throws Exception 

  The definition of a method on the other hand, is the signature of a method plus its "body", that is the actual implementation of the method. For example:

  public int fibonacci(int n) throws Exception
  {
      if(n < 0) throw new Exception("n may not be smaller then 0!");
      else if (n <= 1) return n;
      else return fibonacci(n-1) + fibonacci(n-2);
  }
