Need help with two problems In JAVA please! there very short! Thank you! public static double sumReals(Scanner input)

This method takes an already open Scanner and reads input words from it. If any input word happens to represent a valid real number, it is added to a running total.

When no input remains in the Scanner, this running total is returned. If no words are valid real numbers then 0.0 should be returned. Some example uses in DrJava's interactive loop are shown below.

Problem : public static double sumReals(String parseString)

Instead of taking an already opened Scanner this method takes a String to parse. It should create a Scanner object that reads from the parameter String and then perform the same computation as sumReals(Scanner).

Note that this illustrates that Java methods may have the same name so long as they have different argument types or different numbers of arguments.
