parse
```
public static Object parse(String string,
                           Class clazz)
```
Takes a String (e.g. a user-entered one) and parses it into an object of the specified class

Parameters:

string -

clazz -

Returns:

Object of type clazz with the data from string

collectionContains
```
public static boolean collectionContains(Collection<?> objects,
                                         Object obj)
```
Loops over the collection to check to see if the given object is in that collection. This method only uses the .equals() method for comparison. This should be used in the patient/person objects on their collections. Their collections are SortedSets which use the compareTo method for equality as well. The compareTo method is currently optimized for sorting, not for equality. A null obj will return false

Parameters:

objects - collection to loop over

obj - Object to look for in the objects

Returns:

true/false whether the given object is found Should use equals method for comparison instead of compareTo given List collection Should use equals method for comparison instead of compareTo given SortedSet collection

getOutFile

```
Gets an out File object. If date is not provided, the current timestamp is used. If user is not provided, the user id is not put into the filename. Assumes dir is already created

Parameters:

dir - directory to make the random filename in

date - optional Date object used for the name

user - optional User creating this file object

Returns:

file new file that is able to be written to

generateUid
```
public static String generateUid(Integer size)
```

```
Convenience method to replace Properties.store(), which isn't UTF-8 compliant
NOTE: In Java 6, you will be able to pass the load() and store() methods a UTF-8 Reader/Writer object as an argument, making this method unnecessary.

Parameters:

properties -

file -

comment -

storeProperties
```
public static void storeProperties(Properties properties,
                                   OutputStream outStream,
                                   String comment)
```
Convenience method to replace Properties.store(), which isn't UTF-8 compliant NOTE: In Java 6, you will be able to pass the load() and store() methods a UTF-8 Reader/Writer object as an argument.

Parameters:

properties -

loadProperties
```
public static void loadProperties(Properties props,

NOTE: In Java 6, you will be able to pass the load() and store() methods a UTF-8 Reader/Writer object as an argument, making this method unnecessary.

Parameters:

props - the properties object to write into

inputStream - the input stream to read from

loadProperties
```
public static void loadProperties(Properties props,
                                  File propertyFile)

Parameters:

props - the properties object to be loaded into

propertyFile - the properties file to read
